When NASA’s Aqua satellite passed over tropical cyclone Lane on Aug. 27 it had just regained tropical storm status and showed powerful thunderstorms around east of its center of circulation. Colorado State earlier this month lowered its forecast for the 2018 season, predicting nine storms would form in August or later. Maximum sustained winds are near 65 mph (100 kph) with higher gusts. Lane is then expected to accelerate northwestward by Tuesday as it transitions to an extratropical low. 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). Jet Propulsion Laboratory, Pasadena, Calif. By Rob Gutro NOAA’s Central Pacific Hurricane Center or CPHC said a westward motion with a decrease in forward speed is expected to continue through tonight, followed by a turn to the west-northwest on Wednesday, Sept. 5 and to the northwest on Wednesday night. Maximum sustained winds are near 85 mph (140 kph) with higher gusts. The higher the cloud tops, the colder and the stronger they are. Answer 1 of 10: My fiance and I are trying to determine where to go on our honeymoon next August, and Bermuda is a possibility; however, we're worried about the chance of a hurricane in August. That’s about 940 miles (1,510 km) east-southeast of Hilo, Hawaii. Wherever cloud top temperatures are as cold as or colder than minus 63 degrees Fahrenheit (minus 53 degrees Celsius), those storms have the potential to drop heavy rain. The low pressure area previously known as System 94W strengthened and consolidated enough to be re-classified as a depression. Some strengthening is forecast during the next 48 hours, and Miriam is expected to become a hurricane later today or tonight. Norman was moving toward the west near 8 mph (13 kph), and this motion is expected to continue today. On August 28, 2018 there were no coastal watches or warnings in effect because TD16E formed far from land. It is not close enough to the islands to generate any watches or warnings, however, a large swell generated by Norman peaked across the main Hawaiian Islands overnight on Sept. 6, causing large and potentially dangerous surf along east facing shores. Jebi then reached its peak intensity with sustained winds estimated at 175 mph by the Joint Typhoon Warning Center as it made its way into the Philippine Sea. The estimated minimum central pressure is 999 millibars. Despite the wind shear, Lane strengthened back into a tropical storm on Aug. 27. Jebi then crossed the southern coast of the main island of Honshu near Kobe, bringing heavy rains and high winds to the region. Cloud top temperatures that cold indicate strong storms that have the capability to create heavy rain. These agencies include the Tropical Storm Risk (TSR) Consortium of University College London, the National Oceanic and Atmospheric Administration (NOAA) and Colorado State University(CSU). At 5 a.m. EDT (0900 UTC) on Aug. 28 (11 p.m. HST, Aug. 27) the center of Tropical Depression Lane was located near latitude 18.4 degrees north and longitude 167.4 degrees west. 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. On Aug. 26, there were no coastal watches or warnings in effect. A turn back toward the west is expected on Saturday. Maximum sustained winds have increased to near 60 mph (95 kph) with higher gusts. The Atmospheric Infrared Sounder or AIRS instrument analyzed the storm in infrared light which provides temperature information.

Two days later on the 27th of August the system was upgraded to a tropical depression, which continued to intensify, becoming a named tropical storm, the 21st of the season, the following day. The center of Hurricane Norman was located near latitude 19.5 degrees north and longitude 147.7 degrees west. 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. Tropical Depression 25W is moving toward the north-northwest at 10 mph. 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. NWS said “Residents of the Northern Marianas Islands…including Agrihan, Pagan and Alamagan should carefully monitor the progress of Tropical Depression 25W.”. NOAA’s Central Pacific Hurricane Center or CPHC noted that interests in the Northwestern Hawaiian Islands should continue to monitor the progress of Lane. Reuters / Freitag, August 24, 2018 Hurricane Andrew, 1992: The fourth-most intense hurricane to ever make landfall, Andrew left a trail of destruction across Florida and 23 deaths in the U.S. Additional weakening is forecast through Sunday night. Author Lynn Jenner Posted on August 30, 2019 September 3, 2019 Categories Earth, Earth Hazards, Hurricanes Tags Dorian 2019 Dorian (Atlantic Ocean) Aug 30, 2019 – Update #1 – NOAA’s GOES-East and GOES-15 Capture Dorian’s Movement in the Atlantic The second smaller area was located over east central Japan. CPHC said “Rain bands will continue to overspread the Hawaiian Islands well ahead of Lane. 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).”. Key Messages and Cautions from NOAA’s CPHC. With more than 2,000 channels sensing different regions of the atmosphere, the system creates a global, three-dimensional map of atmospheric temperature and humidity, cloud amounts and heights, greenhouse gas concentrations, and many other atmospheric phenomena. August is not typically the height of hurricane season but Charley and Frances did hit in 2004. For updates on Norman, visit: http://www.prh.noaa.gov/cphc, By Rob Gutro At least 90 people had to be rescued off the shores of Oahu due to dangerous swells generated by the cyclone. 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. A few of these powerful storms were found by the satellite to reach heights above 13.4 km (8.3 miles). Purple shows very cold clouds high in the atmosphere above the center of the hurricane, while blue and green show the warmer temperatures of lower clouds surrounding the storm center. Lane is expected to remain a hurricane as it approaches the islands.”, By Rob Gutro However, CPHC cautioned that interests in the Northwestern Hawaiian Islands should continue to monitor the progress of Lane. 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. A recent microwave image showed a rather well-defined eye. This general motion is expected to continue today, with a gradual turn toward the north-northwest. NOAA’s CPHC said “Lane’s outer rain bands will produce excessive rainfall this weekend, which could lead to additional flash flooding and landslides. Lane is moving toward the west near 8 mph (13 km/h), and this motion is expected to continue today. Over 30 inches of rain has already fallen at a couple locations on the windward side of the Big Island.”. These hurricanes in the past three years all struck during the peak of the season. After initially moving northwest, Jebi took a more westward track and continued to steadily intensify as it approached the Northern Mariana Islands, becoming a typhoon on the 29th, a Category 3 typhoon on the 30th, and finally a super typhoon on the 31st of August (local time) just after it passed between the islands of Pagan and Alamagan in the Northern Marianas. 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. CPHC noted that “large swells generated by Norman will continue to build across the Hawaiian Islands through Thursday. 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. The slow movement of Lane also greatly increases the threat for prolonged heavy rainfall and extreme rainfall totals. Coldest cloud tops were near minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius), east of the center. Warm ocean temperatures and low vertical wind shear are providing a favorable environment for Jebi’s intensification.

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.. NASA’s Goddard Space Flight Center. 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. The depression is moving toward the west near 7 mph (11 kph). That’s about 1,480 miles (2,380 km) east-southeast of Hilo, Hawaii. The GPM satellite’s Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments collected data in a swath that was centered west of tropical storm Jebi’s center of circulation. Lane is expected to produce total rain accumulations of 10 to 20 inches, with localized amounts in excess of 30 inches over the Hawaiian Islands.”. Additional strengthening is forecast during the next 2 to 3 days, and Miriam is expected to become a hurricane tonight or early Tuesday, Aug. 28. Lane is moving toward the north near 5 mph (7 kph), and this general motion is expected to continue through tonight. NASA’s Goddard Space Flight Center. Weakening is forecast through Saturday. The latest satellite view shows a void or organized storms through the tropics. NASA research has found that cloud top temperatures that cold have the capability to generate heavy rainfall. Launched into Earth orbit in 2002, the AIRS and AMSU instruments fly onboard NASA’s Aqua spacecraft and are managed by JPL. Tropical Storm Jebi is forecast to intensify through Thursday, Aug. 30. Gradual weakening is forecast, but Norman is expected to remain a powerful hurricane through the early part of next week. 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. 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). That’s about 161 nautical miles north-northeast of Saipan. On Aug. 29, microwave data showed the low-level center still slightly displaced from the deep convection due to about 11.5 mph (10 knots/18.5 kph) of northwesterly wind shear. Working in tandem, the two instruments make simultaneous observations all the way down to Earth’s surface, even in the presence of heavy clouds. Ryan 1000 12:51, August 6, 2018 (UTC) Wind shear has declined quite a bit in the basin. For updated forecasts on Norman, visit: http://www.prh.noaa.gov/cphc. In a couple of days, Lane may develop into a gale force extratropical low as it passes over portions of the Northwestern Hawaiian Islands. However, NOAA’s Central Pacific Hurricane Center or CPHC said that interests in the Northwestern Hawaiian Islands should continue to monitor the progress of Lane. Jebi was moving toward the north-northeast at 45 mph (39 knots/72kph). 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. By Rob Gutro Tropical cyclones continue to regularly develop in the Eastern Pacific Ocean. On Aug. 24 at 12:40 a.m. EDT (0430 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard Aqua captured a visible light image of Soulik after it moved off the Korean Peninsula. At that time the center of Jebi was located near latitude 38.9 degrees north and longitude 137.7 degrees east. NASA’s Atmospheric Infrared Sounder (AIRS) captured Hurricane Lane when the Aqua satellite passed overhead on Aug. 22 and 23. (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 … Miriam was moving toward the west near 13 mph (20 kph). On Aug. 26 at 0223 UTC (Aug. 25 at 10:23 p.m. EDT) the GPM core observatory satellite revealed that extremely heavy rainfall was occurring within the organizing storm. Some fluctuations in intensity are possible today, followed by gradual weakening from tonight. Storms with cloud top temperatures that cold have the capability to produce heavy rainfall. Northeast Pacific hurricanes and tropical storms in August 2018 had produced 116.2 ACE units through Aug. 29, topping the previous monthly record … Miriam is expected to become a post-tropical remnant low pressure area on Sunday, Sept. 2. This is above the 1981-2010 average of 12.1 named storms, 6.4 hurricanes, and 2.7 major hurricanes. Some additional intensification is expected today, followed by fairly rapid weakening Friday through Saturday night, Sept. 1. Japan has been afflicted by several tropical cyclones and other extreme weather this summer. 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. Much of the band of rain oriented east-west across central Japan was due to a frontal system that brought rain to the area before Jebi made landfall. However, wind shear kicked back up and by 11 p.m. EDT that day, Lane had again weakened back to tropical depression status. In … Weakening is expected over the next couple of days. The environment remains favorable for continued intensification with warm sea surface temperatures, low vertical wind shear, and radial outflow.”. TD15E became better organized with increased banding later in the day and was upgraded by the National Hurricane Center (NHC) to tropical storm Miriam. The 2018 Atlantic hurricane season was the 4th most active season of the 2010s decade, and perhaps Sixth most active overall, spawning 17 Depressions, 15 Storms, 10 hurricanes and a near record 6 Major.The season started with Tropical Storm Alberto forming 2 Days after the official start of the season.Hurricane Beryl became the first Major hurricane of the season in Late-July, whilst co-existing with Hurricane ChrisGordo… The Atmospheric Infrared Sounder or AIRS instrument analyzed the storm in infrared light which provides temperature information. Some strengthening is forecast during the next 48 hours, and the depression is expected to become a tropical storm later today or on Wednesday, and a hurricane by Thursday (Aug. 30).”, For updated forecasts from the NHC, visit: http://www.nhc.noaa.gov. As Tropical Storm Miriam was developing, the GPM or Global Precipitation Measurement mission or GPM core satellite observed the rainfall happening within the storm. 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. Jebi is expected to strengthen and maintain that strength for one and one half days, before finally starting a weakening trend on Sept. 1. The surf is forecast to diminish on Friday, Sept. 7. At 5:40 a.m. EDT (0940 UTC) on Aug. 28 the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard Aqua used infrared data to measure cloud top temperatures in Tropical Depression 16E (TD16E) when it was forming. 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. Maximum sustained winds have increased to 35 mph. On Aug. 31 at 7:15 a.m. EDT (1150 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA’s Terra satellite found the coldest temperatures of the strongest thunderstorms around Jebi’s eye and west of the center. 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. That’s about 349 nautical miles northeast of Yongsan. 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. Miriam is then forecast to weaken back to tropical storm intensity on September 1, 2018. 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). Maximum sustained winds are near 65 mph (100 kph) with higher gusts. Tropical-storm-force winds extend outward up to 80 miles (130 km) from the center. Aqua observed fragmented bands of thunderstorms circling a low-level center of circulation and some stronger storms within them. 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. Terra found powerful storms around the 15 nautical-mile wide eye in this Category 5 storm. At 5 a.m. EDT (2 a.m. PDT/0900 UTC), the center of Tropical Storm Miriam was located near latitude 14.0 degrees north and longitude 133.5 degrees west. 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.
