The CPHC forecast noted that Tropical storm conditions are still expected in and near outer rain bands that will affect Oahu, Maui County and the Big Island today. NASA’s Aqua satellite provided valuable temperature data on Tropical Storm Norman in the Eastern Pacific Ocean. The Integrated Multi-satellitE Retrievals for GPM (the Global Precipitation Measurement mission) or IMERG is used to estimate precipitation from a combination of passive microwave sensors, including GPM’s GMI microwave sensor and geostationary IR (infrared) data. At 5 a.m. EDT on Sept. 7 (11 p.m. HST on Sept. 6) the center of Hurricane Norman was located near latitude 22.5 North, longitude 151.7 degrees west. On Aug. 24 at 5 a.m. EDT (0900 UTC) the Joint Typhoon Warning Center issued the final bulletin on Extratropical Storm Cimaron. August 9, 2018 - NOAA lowers its 2018 forecast to a 30% chance for an above-normal season, with a total of nine to 13 named storms, including zero to two major hurricanes. NOAA’s CPHC said “Lane’s outer rain bands will produce excessive rainfall this weekend, which could lead to additional flash flooding and landslides. Hurricane Miriam heading northwestward across the Central Pacific and is expected to remain far away from land. Coldest cloud tops were near minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius). Water vapor releases latent heat as it condenses into liquid. A decrease in forward speed is expected tonight as Lane makes a turn toward the northwest. There are no coastal watches or warnings in effect as Norman is far from land. Jebi contributed much of the rainfall over Shikoku and most of the rainfall over the south central coastal regions of Honshu where it made landfall before adding to the rainfall amounts across central Honshu. Stronger thunderstorms circled Norman’s center in a thicker ring on Sept. 6 when NASA’s Terra satellite passed over the hurricane. On the latest forecast track, the center of Lane will move dangerously close to portions of the central Hawaiian Islands later today, Aug. 24 and tonight. At least one fatality was blamed on Hurricane Lane. Tropical Depression 25W is moving toward the north-northwest at 10 mph. CPHC said those were located from 50 nautical miles northwest to over 100 nautical miles northeast and east of the center. Tropical Storm Jebi is moving toward the northwest at 10 mph. On the forecast track, Miriam will approach the central Pacific basin late Wednesday or Wednesday night. Miriam is moving toward the west near 14 mph (22 kph), and this general motion is expected to continue for the next couple of days. A few of these powerful storms were found by the satellite to reach heights above 13.4 km (8.3 miles). Atlantic May Spawn Four to Seven Hurricanes in 2018 Storm Season By . NASA’s Aqua satellite passed over Lane on Aug. 27 at 8:17 a.m. EDT (1217 UTC). There was one preliminary report of more than 52 inches of rain. Maximum sustained winds have increased to near 60 mph (95 kph) with higher gusts. Even if the center of Lane remains offshore, severe impacts could still be realized as they extend well away from the center. 818-354-4269 It is expected to make a turn toward the northwest with little change in forward speed during the next 24 hours. The Joint Typhoon Warning Center (JTWC) expects Jebi to start weakening but it is forecast to make landfall between Kyoto and Tokyo, Japan on Sept. 4. 2018 … Infrared satellite data at 4:25 a.m. EDT (0825 UTC) on Sept. 6, from the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA’s Terra satellite showed coldest cloud top temperatures in Norman completely circled the eye in a very wide band. You will need red-blue glasses to view the anaglyph (with the red lens placed over your left eye). There is no eye evident in satellite imagery, which is likely a result of these hostile conditions.”. Just so you know, hurricanes hit Orlando in 2017, 2004, and 1960. A brief slowing in forward motion is expected Monday night as Lane makes a turn toward the northwest. It takes approximately seven minutes for all the cameras to observe the same location, and the motion of the clouds during that time is used to compute the wind speed at the cloudtops. Water vapor analysis of tropical cyclones tells forecasters how much potential a storm has to develop. Tropical Activity on Record Pace in Northeast Pacific. Northeast Pacific hurricanes and tropical storms in August 2018 had produced 116.2 ACE units through Aug. 29, topping the previous monthly record … A Hurricane Warning is in effect for Oahu, Maui County…including the islands of Maui, Lanai, Molokai and Kahoolawe. The East Pacific activity was about average in August with three tropical storms and two hurricanes. month begins. GPM’s radar data (DPR Ku Band) was used here to show a simulated 3D view of tropical storm Jebi’s radar reflectivity values. When NASA’s Aqua satellite passed over Tropical Storm Jebi on Sept. 4 at 12:17 a.m. EDT (417 UTC) it had made landfall in southeastern Japan. Aqua observed fragmented bands of thunderstorms circling a low-level center of circulation and some stronger storms within them. For updates on Norman, visit:  http://www.prh.noaa.gov/cphc, By Rob Gutro   Fortunately, that heavy rain is falling over open ocean waters. When NASA’s Aqua satellite passed over Tropical Storm Miriam Aug. 27 and infrared data showed slight improvement from the day before. Maximum sustained winds were near 35 mph (55 kph) with higher gusts. That’s about 1,485 miles (2,385 km) west-southwest of the southern tip of Baja California, Mexico. Over 30 inches of rain has already fallen at a couple locations on the windward side of the Big Island.”. That’s 290 miles (470 km) northeast of Hilo, Hawaii. At 11 a.m. EDT (1500 UTC) on Sept. 4, the Joint Typhoon Warning Center issued the final warning on Jebi. That’s 480 miles (775 km) east of Hilo, Hawaii. That’s about 630 miles (1,015 km) west-southwest of the southern tip of Baja California, Mexico. Norman was moving toward the west near 10 mph (17 kph). Cimaron was moving northeast and has become extra-tropical and asymmetric. The storms also whipped up winds across the state. NASA research has shown that storms with cloud top temperatures that cold (that are very high in the troposphere) have the capability to generate heavy rain. Norman was moving toward the west near 8 mph (13 kph), and this motion is expected to continue today. That’s about 1,165 miles (1,875 km) east-southeast of Hilo, Hawaii. When NASA’s Terra satellite analyzed water vapor within Tropical Storm Jebi in the Northwestern Pacific Ocean on Aug. 28 found the storm had taken on the classic comma-shape of an organized storm. The depression is moving toward the west near 7 mph (11 kph). Super Typhoon Jebi began as an area of low pressure that formed in the vicinity of Enewetak Atoll in the far western Marshall Islands. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA. Although the official forecast does not explicitly indicate Lane’s center making landfall over any of the islands, this remains a very real possibility. NASA’s Aqua satellite found two areas where cloud top temperatures were coldest and as cold as minus 50 degrees Fahrenheit (minus 45.5 degrees Celsius). The National Hurricane Center (NHC) noted at 11 a.m. EDT (1500 UTC), the eye of Hurricane Norman was located near latitude 16.7 degrees north and longitude 120.8 degrees west. NASA’s Aqua satellite passed over Typhoon Jebi in the Northwestern Pacific Ocean and saw a well-organized typhoon with a small eye. August is not typically the height of hurricane season but Charley and Frances did hit in 2004. Ahead of and during the season, several national meteorological services and scientific agencies forecast how many named storms, hurricanes, and major hurricanes will form during a season or how many tropical cyclones will affect a particular country. A Tropical Storm Warning is in effect for Oahu, Maui County…including the islands of Maui, Lanai, Molokai and Kahoolawe and Hawaii County A Tropical Storm Watch is in effect for Kauai County…including the islands of Kauai and Niihau. By Steve Lang Some strengthening is possible during the next day or two, but Miriam is expected to begin weakening by Friday. Jebi was moving toward the west near 14 mph (12 knots/22kph). It is expected to make a turn toward the west with a slight increase in forward speed over the next 24 hours. NASA’s Goddard Space Flight Center, For earlier information on Lane go to:  https://www.nasa.gov/feature/goddard/2018/lane/, Aug. 24, 2018 – NASA Tracks Tropical Storm Soulik into the Sea of Japan. Slight weakening is forecast during the next 48 hours. Isolated tornados are possible through this morning across parts of the Big Island, Maui County and Oahu. Miriam was moving toward the west near 13 mph (20 kph). For updated forecasts, visit: www.nhc.noaa.gov. In the Aug. 22 image, a prominent eye is also visible. GPM found in an intense feeder band of thunderstorms south of Jebi’s center where precipitation was falling at a rate of over 87 mm (3.4 inches) per hour. On Sept. 4 at 7:24 p.m. EDT (2324 UTC) the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA’s Suomi NPP satellite captured a visible image of Hurricane Norman. The higher the cloud tops, the colder and the stronger they are. Ranging from a pair of destructive Atlantic hurricanes to storms that produced hail the size of baseballs, 2018 was another year where numerous … Might as well start this section before the (busiest?) GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA. In … On the forecast track, the center of Lane will move very close to or over the main Hawaiian Islands later today through Friday (Aug. 24).”. Temperature is important when trying to understand how strong storms can be. Norman is expected to remain a hurricane through Thursday, Sept. 6. 2019: Hurricane Dorian (Aug. 24-Sept. 7) 2018 : Hurricane Florence (Aug. … Soulik is speeding to the northeast at 36 knots (41 mph/67 kph) and maximum sustained winds are near 35 knots (40 mph/62 kph) with higher gusts. That happens when a new eyewall or ring of thunderstorms within the outer rain bands forms further out from the storm’s center, outside of the original eye wall. Temperature is important when trying to understand how strong storms can be. A turn toward the west is anticipated on Saturday, with an increase in forward speed. Lane then took a more westward turn, away from the islands and dissipated by the 29th. On Sept 4, the MODIS instrument aboard NASA’s Aqua satellite showed a band of strong storms that circled the center was much thinner. The second smaller area was located over east central Japan. Aqua took a look at the storm in infrared light that provided temperature data to reveal the location of the most powerful thunderstorms that make up the tropical cyclone. The tropical storm was about 185 nautical miles west-southwest of Misawa, Japan. Working in tandem, the two instruments make simultaneous observations all the way down to Earth’s surface, even in the presence of heavy clouds. Maximum sustained winds have increased to near 150 mph (240 kph) with higher gusts. Anonymous 2.0 (talk) 16:52, July 31, 2018 (UTC) And Tropical Tidbits spots another invest, also in the open Pacific. A Typhoon Watch means destructive winds of 74 mph or more are possible within the next 48 hours. MODIS saw coldest cloud top temperatures were as cold as minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius) in three areas around the center of circulation. Despite the drop in strength, the heavy rains persist over the Hawaiian Islands. The List of Florida hurricanes encompasses approximately 500 tropical or subtropical cyclones that affected the state of Florida.More storms hit Florida than any other U.S. state, and since 1851 only eighteen hurricane seasons passed without a known storm impacting the state. Some additional strengthening is forecast during the next 12 to 24 hours. Warm ocean temperatures and low vertical wind shear are providing a favorable environment for Jebi’s intensification. Computer forecast models show that Soulik and Cimaron would remain two separate systems. The National Hurricane Center (NHC) noted today, Aug. 29 that Norman is forecast to rapidly intensify and become a hurricane later today. No eye is visible on the Aug. 23 image, either because it was too small for AIRS to detect or it was covered by high, cold clouds. In a couple of days, Lane may develop into a gale force extratropical low as it passes over portions of the Northwestern Hawaiian Islands. On Tuesday, August 28, 2018, the National Hurricane Center (NHC) noted that Miriam’s cloud pattern had still not improved very much from Aug. 27. So far, the storm is being blamed for 11 fatalities and as many as 300 injuries in Japan. Norman is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. This is above the 1981-2010 average of 12.1 named storms, 6.4 hurricanes, and 2.7 major hurricanes. However, the early part of the season was unusually inactive, so most measures of seasonal activity remain in the bottom third of the last 40 years. Temperature is important when trying to understand how strong storms can be. On Sept. 6, Major Hurricane Norman was east of the Hawaiian Islands and tracking toward the west-northwest. The Season had a Semi-Late Start, with Tropical Storm Alberto forming on June 30th.. When NASA’s Aqua satellite passed over Hurricane Norman on Aug. 30 infrared data showed very cold storm tops around a 20 nautical-mile-wide eye. There is also some drier air working its way into the circulation. Banding continues to increase, with the convective canopy expanding in nearly all quadrants.”. The National Weather Service (NWS) in Tiyan, Guam noted at 11 a.m. EDT (1 a.m. CHST local time/1500 UTC) on Aug. 27, the center of Tropical Depression 25W was located near Latitude 14.5 degrees North and Longitude 158.4 degrees East. Aqua data showed Norman was quickly intensifying. Some strengthening is forecast during the next 48 hours, and Miriam is expected to become a hurricane later today or tonight. A turn toward the west-northwest with a decrease in forward speed is expected by tonight, followed by a turn toward the northwest and north through Friday night. Overnight, Norman remained generally steady but had some recent development of new deep convection very close to the estimated low-level circulation center. There are no watches or warnings in effect. Lane will pass dangerously close to the main Hawaiian Islands as a hurricane on Friday, and is expected to bring damaging winds. Some additional intensification is expected today, followed by fairly rapid weakening Friday through Saturday night, Sept. 1. The environment remains favorable for continued intensification with warm sea surface temperatures, low vertical wind shear, and radial outflow.”. NASA research has shown that storms with cloud top temperatures that cold (that are very high in the troposphere) have the capability to generate heavy rain. Miriam is expected to become a post-tropical remnant low pressure area on Sunday, Sept. 2. AIRS saw coldest cloud top temperatures being pushed slightly east of center by light vertical wind shear. Norman is forecast to continue to move toward the northwest on Friday and Saturday, and along the forecast track, the center of Norman is expected to pass 200 to 300 miles to the northeast of the main Hawaiian Islands. On Aug. 30 at 11 a.m. EDT (5 a.m. HST/1500 UTC) NOAA’s Central Pacific Hurricane Center or CPHC noted the center of Hurricane Miriam was located near latitude 15.3 degrees north and longitude 141.6 degrees west. The GPM was coupled with an infrared image from NOAA’s GOES-West satellite to show the clouds of the tropical storm and form and entire picture. At least 90 people had to be rescued off the shores of Oahu due to dangerous swells generated by the cyclone. CPHC said, “Some weakening is forecast during the next day or so, with more significant weakening thereafter. Infrared satellite imagery shows scientists where the coldest cloud tops are located in a tropical cyclone and can give a clear picture of wind shear’s effects. Maximum sustained winds have increased to 35 mph. On Aug. 29 at 4:45 a.m. EDT (0845 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA’s Aqua satellite found the coldest temperatures of the strongest thunderstorms in Tropical Storm Norman were north and south of the center and were as cold as or colder than minus 80 degrees Fahrenheit (minus 62.2 Celsius). NOAA’s Central Pacific Hurricane Center or CPHC noted that a Hurricane Warning is in effect for Oahu, Maui County including the islands of Maui, Lanai, Molokai and Kahoolawe and Hawaii County. A turn toward the north is expected later today, with this motion continuing through Friday night. By Rob Gutro Lane is expected to produce total rain accumulations of 10 to 20 inches in some areas. Excessive rainfall associated with this slow moving hurricane will continue to impact the Hawaiian Islands into the weekend, leading to catastrophic and life-threatening flash flooding and landslides. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 90 miles (150 km). At 11 a.m. EDT (5 a.m. HST/1500 UTC), the center of Tropical Depression Lane was located near latitude 19.1 North, longitude 162.2 West. On Aug. 28, NOAA’s Central Pacific Hurricane Center or CPHC noted that there were no coastal watches or warnings in effect. Those cloud top temperatures were as cold as minus 63 degrees Fahrenheit (minus 53 degrees Celsius). CPHC said, “Hurricane Lane is beginning to show some signs of slow weakening due to wind shear of over 20 knots from the southwest according to the SHIPS and UW-CIMSS analyses. That liquid becomes clouds and thunderstorms that make up a tropical cyclone. The National Hurricane Center's Tropical Cyclone Reports contain comprehensive information on each tropical cyclone, including synoptic history, meteorological statistics, casualties and damages, and the post-analysis best track (six-hourly positions and intensities). Maximum sustained winds have increased to 45 mph. For updated forecasts on Norman, visit:  http://www.prh.noaa.gov/cphc. The Atmospheric Infrared Sounder or AIRS instrument analyzed the storm in infrared light which provides temperature information. On Aug. 31 at 7:15 a.m. EDT (1150 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA’s Aqua satellite found the coldest temperatures of the strongest thunderstorms Hurricane Miriam were southwest of the center and were as cold as or colder than minus 80 degrees Fahrenheit (minus 62.2 Celsius). On Tuesday, August 28, 2018, the National Hurricane Center (NHC) noted that Miriam’s cloud pattern had still not improved very much from Aug. 27. NASA Goddard Space Flight Center. August 9, 2018 US forecasts even fewer hurricanes in Atlantic for 2018 ... NOAA had anticipated a "near-normal" year with 10 to 16 named storms, including five to nine of hurricanes in 2018. A turn toward the northwest and north-northwest is expected Thursday, Aug. 30 and Friday, Aug. 31. The state has been dealing with moderate drought for several months and the winds caused a wildfire to burn out of control on Maui destroying 20 homes. The higher the cloud tops, the colder and the stronger they are. CPHC noted that “large swells generated by Norman will continue to build across the Hawaiian Islands through Thursday. GPM found heavy rainfall occurring in a band of thunderstorms wrapping into the low-level center from the western quadrant where rain was falling at a rate of over 10 inches (263.3 mm/hour). Maximum sustained winds are near 90 mph (150 kph) with higher gusts. There is a wave entering the Eastern Caribbean, but it will be fighting some wind sheer. Then, that outer ring of thunderstorms chokes off the original eye wall, starving it of moisture and momentum. NOAA’s Central Pacific Hurricane Center or CPHC said at 8 a.m. EDT (2 a.m. HST) today, Saturday, August 25, 2018, “Lane’s outer rain bands producing severe flooding across parts of the Hawaiian Islands.”. However, CPHC cautioned that interests in the Northwestern Hawaiian Islands should continue to monitor the progress of Lane. AIRS saw coldest cloud top temperatures around the center and in a large band of thunderstorms extending east and south of the center. NASA’s Goddard Space Flight Center. Maximum sustained winds are near 65 mph (100 kph) with higher gusts. August 9, 2018, 11:17 AM EDT 2:37. On Aug. 31 at 6:10 a.m. EDT (1010 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA’s Aqua satellite found the coldest temperatures of the strongest thunderstorms in Hurricane Norman were southeast of the center and were as cold as or colder than minus 80 degrees Fahrenheit (minus 62.2 Celsius). A turn toward the northwest is expected Thursday and Thursday night. A Hurricane Watch is in effect for Kauai County…including the islands of Kauai and Niihau. That’s about 161 nautical miles north-northeast of Saipan. Maximum sustained winds have decreased to near 130 mph (215 kph) with higher gusts. The Atmospheric Infrared Sounder or AIRS instrument analyzed the storm in infrared light which provides temperature information. The storm’s intensity can fluctuate over this period, initially weakening as the inner eye wall fades before again strengthening as the outer eye wall contracts. Author Lynn Jenner Posted on December 21, 2018 Categories Earth, Earth Hazards, Hurricanes Tags Cilida 2018 Cilida (Southwestern Indian Ocean) December 20, 2018 – NASA-NOAA Satellite Catches the Eye of Rapidly Intensifying Tropical Cyclone Cilida . These hurricanes in the past three years all struck during the peak of the season. The once hurricane that dropped record-setting rainfall on the Hawaiian Islands has come to an end in the Central Pacific Ocean and NASA-NOAA’s Suomi NPP satellite captured a visible image of its final hours. Launched into Earth orbit in 2002, the AIRS and AMSU instruments fly onboard NASA’s Aqua spacecraft and are managed by JPL. Large and potentially dangerous surf is expected along east facing shores through at least Thursday night, Sept. 6.”, For updates on Norman, visit: http://www.prh.noaa.gov/cphc/. At 8 a.m. EDT (2 a.m. HST/1200 UTC) on Aug. 23, the eye of Hurricane Lane was located by satellite and radar near latitude 16.5 degrees north and longitude 157.3 degrees west. Credit: NASA/JAXA, Hal Pierce. The slow movement of Lane also greatly increases the threat for prolonged heavy rainfall and extreme rainfall totals. The Central Pacific Hurricane Center (CPHC) noted at 11 a.m. EDT (5 a.m. HST/1500 UTC), the center of Hurricane Miriam was located near latitude 18.3 degrees north and longitude 141.2 degrees west. Hurricane-force winds extend outward up to 40 miles (65 km) from the center and tropical-storm-force winds extend outward up to 140 miles (220 km). The JTWC predicts that the typhoon will have peak sustained winds of 115 knots (132 mph) as it moves over the northern Pacific Ocean toward Japan next week. That’s about 940 miles (1,510 km) east-southeast of Hilo, Hawaii. Jet Propulsion Laboratory, Pasadena, Calif. MISR, flying onboard NASA’s Terra satellite, carries nine cameras that observe Earth at different angles. Maximum sustained winds have increased to near 65 mph (100 kph) with higher gusts. Tropical Depression 25W is forecast to intensify through Wednesday possibly becoming a tropical storm. Over the central Philippine Sea, Jebi began to recurve toward the northwest before eventually turning northward under the influence of an upper-level trough as it neared Japan. Weakening is expected over the next couple of days. More information about MISR is available at these sites:  https://www-misr.jpl.nasa.gov/, https://eosweb.larc.nasa.gov/project/misr/misr_table, More information about AIRS is at: https://airs.jpl.nasa.gov/, Esprit Smith NASA’s IMERG surface rainfall accumulations were calculated for the period 22 to 27 August 2020 for both Hurricanes Marco and Laura. For updated forecasts, visit:  http://www.prh.noaa.gov/cphc. Rainfall is expected to be the biggest threat from Lane. (MORE: Atlantic Basin Could Have Zero Hurricanes in August 2018) The year with the fewest number of named storms, four, and the lowest ACE, 17 units, is … The Atmospheric Infrared Sounder or AIRS instrument analyzed the storm in infrared light which provides temperature information. Jebi was moving to the west-northwest at 14 mph (12 knots/22 kph). This should become Kristy as it tracks west even if it's taking its sweet time now. For local effects in the CNMI, visit: https://forecast.weather.gov/product.php?issuedby=PQ1&product=HLS&site=nws&format=txt, For updated forecasts from the National Weather Service in Tiyan, Guam: http://www.prh.noaa.gov/guam/cyclone.php. The Global Precipitation Measurement mission or GPM core observatory satellite passed above on August 28, 2018 at 2:16 p.m. EDT (1816 UTC) when Jebi was still a tropical storm. August 22 2018 01:00 PM EDT weather.com. NASA and the Japan Aerospace Exploration Agency’s Global Precipitation Measurement mission or GPM satellite measured rainfall rates at 12:46 a.m. EDT (0446 UTC) and found the southwestern tip of the Island of Hawaii and the west coast were receiving rainfall at a rate over 1.2 inches per hour. Jebi’s center crossed near Kyoto before it emerged into the Sea of Japan where it is getting caught up in the mid-latitude westerly jet stream. One larger area was located in west central Japan and moving into the Sea of Japan. Jebi is forecast to pass to the south and west of Iwo To island on the way to the big island of Japan. Despite the wind shear, Lane strengthened back into a tropical storm on Aug. 27. For updated forecasts, visit the National Hurricane Center website:   www.nhc.noaa.gov. This will likely be followed by a turn toward the west with an increase in forward speed starting later today or tonight. The Season collectively caused $19.6 billion in damage … August 29 2018. The hurricane is expected to make a turn to the north in a few days as it moves into the central Pacific Ocean. At 5 a.m. EDT (0900 UTC) on Sept. 6 (11 p.m. HST on Sept. 5), the center of Hurricane Norman was located near latitude 20.3 degrees north and longitude 149.8 degrees west. They were as cold as or colder than minus 80 degrees Fahrenheit (minus 62.2 Celsius). By Aug. 25, Hurricane Lane had weakened to a tropical storm. Lane is then expected to accelerate northwestward by Tuesday as it transitions to an extratropical low. At 8:15 a.m. EDT (1215 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard Aqua measured cloud top temperatures in Lane when it was a depression. Storms with cloud top temperatures that cold have the capability to produce heavy rainfall. At 11 a.m. EDT (1500 UTC) on Aug. 24, the center of Tropical Storm Soulik was located near 41.0 degrees north latitude and 133.0 degrees east longitude. On Aug. 28, wind shear was still affecting the storm. Hurricane Lane’s cloud top temperatures were colder than that, meaning that the storm has a potential to drop even heavier rainfall. On Monday, August 27, 2018 there were no coastal watches or warnings in effect. Credit: NASA/JAXA, Hal Pierce. We are now in the prime time period for tropical storms and hurricanes in the Atlantic basin, yet all is quiet. GPM analyzed Typhoon Jebi as it was making its way toward Japan. So infrared light as that gathered by the MODIS instrument can identify the strongest sides of a tropical cyclone. Accumulated IMERG rainfall estimates over Japan and the surrounding region for the 1-week period from August 29 to Sept. 5, 2018 show rainfall amounts on the order of 100 mm (~4 inches, shown in red) or more covering much of the main island of Honshu and Shikoku in the south. Lane may strengthen as an extratropical low as it passes over portions of the Northwestern Hawaiian Islands from Tuesday night through Thursday, Aug. 30. CPHC said, “The cloud-filled eye continues to be surrounded by a solid ring of cold cloud tops, with lightning bursts persisting in the northern eye wall for the last several hours.”, CPHC also noted, “Excessive rainfall associated with Lane will impact the Hawaiian Islands into the weekend, leading to significant and life-threatening flash flooding and landslides. Lane is then expected to accelerate toward the northwest on Tuesday, Aug. 28 and Wednesday, Aug. 29. esprit.smith@jpl.nasa.gov. On Friday, a turn toward the north is anticipated as Lane’s forward motion slows even more. NWS said “Residents of the Northern Marianas Islands…including Agrihan, Pagan and Alamagan should carefully monitor the progress of Tropical Depression 25W.”. When Terra passed over Super Typhoon Jebi it appeared to be undergoing eyewall replacement. Little change in strength is forecast during the next 48 hours, with Norman forecast to remain a hurricane through Wednesday night. Lane is a powerful category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. NASA’s Multi-angle Imaging SpectroRadiometer (MISR) captured images of Lane on just before noon local time on Aug. 24. NASA’s Aqua satellite looked at Cimaron in infrared light and saw cloud tops were warming as the elongated storm weakened. Lane became a tropical storm later that day. When NASA’s Aqua satellite passed over Hurricane Miriam, it was moving to the northwest and was no threat to land areas in the Central Pacific Ocean. Mature, intense tropical cyclones can and often undergo an eyewall replacement cycle. Infrared satellite data at 7:25 a.m. EDT (1125 UTC) on Sept. 4, from the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA’s Aqua satellite showed coldest cloud top temperatures in Norman were around the eye and southwest of the eye. Large swells generated by Lane will impact the Hawaiian Islands. Some additional strengthening is forecast during the next 12 to 24 hours. MODIS saw coldest cloud top temperatures were as cold as minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius) around the center of circulation and in a thick band of thunderstorms spiraling into the center from the east and southeast.
