NASA’s Aqua satellite observed Hurricane Lane in infrared light to those temperatures. 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. GPM is a joint satellite mission between NASA and the Japan Aerospace Exploration Agency, JAXA. Water vapor releases latent heat as it condenses into liquid. The Season collectively caused $19.6 billion in damage … It was located about 420 miles (675 km) south-southwest of the southern tip of Baja California, Mexico. Weakening is forecast through Saturday. Credit: NASA/NRL. At the time, Norman was a Category 1 hurricane on the Saffir-Simpson hurricane wind scale with maximum sustained winds near 80 mph (70 knots/129.6 kph). 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. 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. For updated forecasts from the CPHC, visit: http://www.prh.noaa.gov/cphc. Tropical Storm Jebi is moving toward the northwest at 10 mph. 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). Lane is expected to produce total rain accumulations of 10 to 20 inches, with localized amounts up to 40 inches possible over portions of the Hawaiian Islands. This view looking toward the southwest, reveals that downpours in the feeder band south of Jebi’s center were found by the satellite to reach heights above 13.4 km (8.3 miles). NOAAs National Hurricane Center said “Maximum sustained winds are near 35 mph (55 kph) with higher gusts. The higher the cloud tops, the colder and the stronger they are. That heavy rain was falling over open ocean waters. That’s about 345 miles northwest of Enetewak, and about 525 miles north of Pohnpei. The depression is moving toward the west-northwest near 10 mph (17 kph), and this motion is expected to continue for the next day or so with a gradual turn to the west thereafter. Maximum sustained winds are near 65 mph (100 kph) with higher gusts. Eventually, if the cycle is completed, the original eye wall of thunderstorms dissipates and the new outer eye wall of thunderstorms contracts and replace the old eye wall. As Norman intensified, the stronger storms expanded further out from the eye. Lane may strengthen as an extratropical low as it passes over portions of the Northwestern Hawaiian Islands from Tuesday night through Thursday, Aug. 30. The image shows the storm as viewed by the central, downward-looking camera. They were embedded in a large area of storms where cloud top temperatures were as cold as or colder than minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius). Miriam is moving toward the northwest near 8 mph (13 kph). On Aug. 28, wind shear was still affecting the storm. At 11 a.m. EDT (1500 UTC) on Sept. 4, the Joint Typhoon Warning Center issued the final warning on Jebi. Miriam was moving toward the west near 12 mph (19 kph), and the NHC said this motion is expected to continue through Wednesday. NASA’s Aqua satellite obtained a visible image of Hurricane Norman northeast of the Hawaiian Islands and found the storm weakening and battling wind shear. Tropical cyclones continue to regularly develop in the Eastern Pacific Ocean. 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. Norman is moving toward the northwest near 8 mph (13 km/h) and this motion is expected to continue through Saturday, remaining east of the main Hawaiian Islands. August 29 2018. Banding continues to increase, with the convective canopy expanding in nearly all quadrants.”. This will likely be followed by a turn toward the west with an increase in forward speed starting later today or tonight. Stronger thunderstorms circled Norman’s center in a thicker ring on Sept. 6 when NASA’s Terra satellite passed over the hurricane. There is a wave entering the Eastern Caribbean, but it will be fighting some wind sheer. That liquid becomes clouds and thunderstorms that make up a tropical cyclone. Maximum sustained winds are near 85 mph (140 kph) with higher gusts. For updated forecasts on Norman, visit: www.nhc.noaa.gov. The number of named storms ranked as a tie for the tenth most on record. Jebi was moving toward the west near 14 mph (12 knots/22kph). NASA’s Aqua satellite flew over Tropical Storm Soulik after it moved into the Sea of Japan and saw that wind shear was adversely affecting the storm. Some additional intensification is expected today, followed by fairly rapid weakening Friday through Saturday night, Sept. 1. By Rob Gutro 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. NASA’s Aqua satellite passed over Norman on Aug. 30 at 5:29 a.m. EDT (0929 UTC). 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. A brief slowing in forward motion is expected Monday night as Lane makes a turn toward the northwest. That’s about 349 nautical miles northeast of Yongsan. 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. August 22 2018 01:00 PM EDT weather.com. Since the AIRS overpass, however, cloud tops have been warming in the southeast. 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. On Aug. 29 at 11 a.m. EDT (1500 UTC), Jebi’s maximum sustained winds were near 80 mph (70 knots/129.6 kph). 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. They were embedded in a large area of storms that circled the eye where cloud top temperatures were as cold as or colder than minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius). 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. Maximum sustained winds were near 63 mph (55 knots/102 kph) with higher gusts. 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. Large and damaging surf can be expected along exposed shorelines, especially along south and west facing coasts, with localized storm surge exacerbating the impacts of a prolonged period of damaging surf. Maximum sustained winds are near 90 mph (150 kph) with higher gusts. Maximum sustained winds have increased to 45 mph. The 2018 Atlantic hurricane season was a Slightly Below Average to near normal hurricane season, primarily caused by Moderate El-Nino Conditions, this season spawned 12 Depressions, 10 Named Storms, 5 hurricanes and 1 Major.. NOAA’s CPHC said “Lane’s outer rain bands will produce excessive rainfall this weekend, which could lead to additional flash flooding and landslides. 818-354-4269 The eye was covered by clouds which made the center difficult to locate. By Rob Gutro With a week to go in the month, there is a growing chance that August 2018 could finish with no hurricane activity. The estimated minimum central pressure is 999 millibars. It is expected to make a turn toward the northwest with little change in forward speed during the next 24 hours. Ryan 1000 12:51, August 6, 2018 (UTC) Wind shear has declined quite a bit in the basin. GPM’s radar data (DPR Ku Band) was used here to show a simulated 3D view of tropical storm Jebi’s radar reflectivity values. Soulik is located to the southwest of Cimaron, National Aeronautics and Space Administration, Jebi (was 25W – Northwestern Pacific Ocean) 2018, https://forecast.weather.gov/product.php?issuedby=PQ1&product=HLS&site=nws&format=txt, https://www.nasa.gov/feature/goddard/2018/lane/, https://www.nasa.gov/feature/goddard/2018/soulik-northwestern-pacific, Cimaron (Northwestern Pacific Ocean) 2018, NASA Aids Disaster Response after Eta and Iota Hit Central America. History tells us that August is the second most active month for tropical systems, and peaking in the first two weeks of September. A Hurricane Warning is in effect for Oahu, Maui County…including the islands of Maui, Lanai, Molokai and Kahoolawe. Nevertheless, Jebi was the strongest typhoon to make landfall in Japan in 25 years when it came ashore over the eastern end of Shikoku, the smallest of Japan’s four main islands, Tuesday, September 4th around noon (local time), where winds gusts of up to 129 mph were reported. The image has been rotated in such a way that north is at the bottom. AIRS saw coldest cloud top temperatures being pushed slightly east of center by light vertical wind shear. Gradual weakening is forecast, but Norman is expected to remain a powerful hurricane through the early part of next week. Storms with cloud top temperatures that cold have the capability to produce heavy rainfall. Cimaron was moving to the north-northeast and had maximum sustained winds near 45 knots (52 mph/83 kph). 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. Temperature is important when trying to understand how strong storms can be. NASA’s Aqua satellite observed Cimaron in infrared light that revealed cloud top temperatures on Aug. 24 at 12:40 a.m. EDT (4:40 UTC) were coldest (yellow) and as cold as minus 50 degrees Fahrenheit (minus 45.5 degrees Celsius) in west central Japan. A turn toward the west and west-northwest with an increase in forward speed is expected over the weekend and into next week. This general motion is expected to continue today, with a gradual turn toward the north-northwest. A satellite image that combines infrared data from NOAA’s GOES-West satellite to show clouds with rainfall data from NASA/JAXA’s GPM satellite. Cimaron has crossed the big island of Japan and became an extra-tropical cyclone. When NASA’s Aqua satellite passed over Tropical Storm Miriam Aug. 27 and infrared data showed slight improvement from the day before. For updated forecasts, visit: www.nhc.noaa.gov. An infrared look by NASA’s Terra satellite provided forecasters with temperature data in the Category 4 hurricane near Hawaii. Lane is moving toward the west near 8 mph (13 km/h), and this motion is expected to continue today. Hurricane Lane was a long-live tropical cyclone that tracked from the East Pacific basin into the Central Pacific basin between August 15th and 29th. A Tropical Storm Warning is in effect for Hawaii County. In both of those areas, cloud top temperatures were as cold as minus 63 degrees Fahrenheit (minus 53 degrees Celsius). Lane is moving toward the north near 5 mph (7 kph), and this general motion is expected to continue through tonight. For updated forecasts, visit: http://www.prh.noaa.gov/cphc. 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. NASA’s Aqua satellite passed over Lane on Aug. 27 at 8:17 a.m. EDT (1217 UTC). AIRS saw coldest cloud top temperatures being pushed east of center by strong vertical wind shear. Storms with cloud top temperatures that cold have the capability to produce heavy rainfall. By Rob Gutro Those cloud top temperatures were as cold as minus 63 degrees Fahrenheit (minus 53 degrees Celsius). Lane formed from a weak low pressure system off the southwest coast of Mexico, reaching tropical depression strength on the 15th. A turn back toward the west is expected on Saturday. 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/. Lane is now Category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale. 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. NASA-NOAA’s Suomi NPP satellite flew over Post-Tropical Cyclone Lane on Aug. 28 at 7:54 p.m. EDT (2354 UTC).The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA’s Suomi NPP satellite provided a visible image that showed wind shear has taken its toll on the storm and pushed all of the clouds northeast of the cloud-less center of circulation. 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. A turn toward the west-northwest is expected on Thursday. Because the storm has strengthened and is now threatening populated areas, a Typhoon Watch is in effect for Agrihan, Pagan and Alamagan in the in the CNMI. As Tropical Storm Miriam was developing, the GPM or Global Precipitation Measurement mission or GPM core satellite observed the rainfall happening within the storm. By Steve Lang Lane then took a more westward turn, away from the islands and dissipated by the 29th. This westward motion is forecast to continue through Sunday. By Rob Gutro 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). However, CPHC cautioned that interests in the Northwestern Hawaiian Islands should continue to monitor the progress of Lane.
