Almost immediately, strong convection fired up near Lauraâs core, lowering the central pressure, and by 7:15 a.m. CDT on Tuesday August 25th, Laura was a Category 1 hurricane. A Storm Surge Warning means there is a danger of life-threatening inundation, from rising water moving inland from the coastline, during the next 36 hours in the indicated locations. NASAâs Earth Observing System Data and Information System (EOSDIS) Worldview application provides the capability to interactively browse over 700 global, full-resolution satellite imagery layers and then download the underlying data. However, as Laura neared and crossed western Cuba on the evening of the 24th, it was already showing signs of becoming better organized though it remained at tropical storm intensity. Maysak is moving to the west-southwest and has maximum sustained winds near 35 knots (40 mph). By the weekend, Hernan is expected to absorb nearby Tropical Storm Iselle. Aug. 28, 2020 – NASA’s captures powerful Hurricane Laura over Louisiana. Aug. 03, 2020 – NASA Finds an Eye and a Giant “Tail” in Typhoon Hagupit NASA-NOAA’s Suomi NPP satellite provided forecasters with a visible image of Typhoon Hagupit in the Northwestern Pacific Ocean that showed the development of an eye as it quickly intensified. NASAâs IMERG surface rainfall accumulations were calculated for the period 22 to 27 August 2020 for both Hurricanes Marco and Laura. NASA brings together technology, science, and unique global Earth observations to provide societal benefits and strengthen our nation. NASA research has determined that cloud top temperatures as cold as or colder than minus 63 degrees Fahrenheit (minus 52.7 degrees Celsius) has the capability to generate heavy rainfall. A turn to the west is forecast this weekend. A Texas Coastal Ocean Observing Network site at Sabine Pass on the Texas/Louisiana border reported sustained winds of 74 mph (119 kph) with a gust to 90 mph (145 kph). The photos showed the extent of this large hurricane. 9 signal (the second highest storm warning) for the first time since Typhoon "Mangkhut" in … Reports from NHC showed that maximum sustained winds increased from 75 to 150 mph over this period, taking Laura from Category 1 to a Category 4 hurricane. Satellite imagery, photographs from the International Space Station, and a computer program that produces animations of imagery are all things that NASA used to analyze the storm. This near-real time rain estimate comes from the NASA’s IMERG algorithm, which combines observations from a fleet of satellites, in near-real time, to provide near-global estimates of precipitation every 30 minutes. The estimated minimum central pressure is 1001 millibars. Month: August 2020 Maysak – Northwestern Pacific Ocean Aug. 31, 2020 – NASA Finds Typhoon Maysak Moving Near Okinawa, Japan Typhoon Maysak continued to move through the Northwestern Pacific and was closing in on Japan’s Okinawa Island when NASA’s Terra satellite obtained a visible image of the storm. Accumulations include the effects from both Laura and Marco. A gradual turn toward the north-northwest and north is expected later today and tonight. Rainfall totals near the mouth of the Mississippi where the center made landfall are much lower and reflects the stormâs asymmetric structure due to the strong wind shear where most of the thunderstorms and associated rainfall occurred well northeast of the center. After passing very near the southwest coast of Puerto Rico, Laura crossed directly over the island of Hispaniola on the night of the 22nd; however, despite being over land, Laura continued to generate deep convection and emerged off the west coast of Haiti with sustained winds reported at 50 mph by NHC on the morning of the 23rd. Typhoon Bavi approaching Fishing boats take shelter at Hallim Port on South Korea's southern Jeju Island on Aug. 25, 2020, as Typhoon Bavi moves north toward the Korean Peninsula, (Yonhap) (END) General 10:02 August 25, 2020 Hurricane Laura began as a tropical depression on August 21st near the U.S. Virgin Islands, and over the next several days rapidly intensified to a dangerous category 4 hurricane at it moved towards the U.S. Gulf Coast. The northern Gulf Coast, specifically Louisiana, saw two tropical cyclones make landfall in the same week just days apart. The Lake Charles, Louisiana airport reported a sustained wind of 85 mph (137 kph) with a gust to 128 mph (206 kph) around 2 a.m. CDT/3 a.m. EDT. The estimated minimum central pressure is 1001 millibars. Health Alert – December 22, 2020 The depression is moving toward the west-northwest near 21 mph (33 kph) and this motion is expected to continue through tonight. Maximum sustained winds have decreased to near 35 mph (55 kph) with higher gusts. Although the wind shear kept Marco from really intensifying, the warm Gulf waters supported enough convection for Marco to reach hurricane intensity around midday on Sunday the 23rd. NASAâs expertise in space and scientific exploration contributes to essential services provided to the American people by other federal agencies, such as hurricane weather forecasting. The imagery spanned from Aug. 20 to 26 and showed Tropical Storm Marco move from the Caribbean Sea to a landfall near the mouth of the Mississippi while Tropical Storm Laura moved from the east over Puerto Rico, Hispaniola and into the Gulf of Mexico, just before landfall in southwestern Louisiana. Applies for tickets issued on or before August 25, 2020. This asymmetric cloud pattern is due to a moderate amount of easterly wind shear. At 5 a.m. EDT (0900 UTC), the center of Tropical Storm Iselle was located near latitude 17.9 degrees north and longitude 115.0 degrees west. At this point, another key factor came into play. After 4 consecutive months of inactivity in the Western Pacific basin, a low-pressure area was first noted on May 9 by the JTWC near Micronesia and was given a medium chance of developing into a tropical cyclone. Tropical storm conditions will spread northward within the warning areas through the day. That is because infrared data provides temperature information, and the strongest thunderstorms that reach highest into the atmosphere have the coldest cloud top temperatures. Hurricanes/tropical cyclones are the most powerful weather events on Earth. The risk for a couple of tornadoes should redevelop Saturday afternoon and evening over parts of the mid-Atlantic from Virginia to North Carolina.”. NASAâs Visible Image Of Cat 4 Hurricane Laura on Aug. 26. It was moving to the north-northwest and had maximum sustained winds near 100 knots (115 mph/185 kph). Many of the available imagery layers are updated within three hours of observation, essentially showing the entire Earth as it looks âright now.â, Tropical Storm Kyle on Saturday, August 15, 2020.

On Aug. 28 at 1 a.m. EDT (0500 UTC), the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASAâs Terra satellite captured an infrared image of cloud top temperatures in Hernan that showed what appears to be its final burst of strength. NASAâs Goddard Space Flight Center, National Aeronautics and Space Administration, NASA Aids Disaster Response after Eta and Iota Hit Central America. On Aug. 28, Flash Flood Watches were posted for portions of northeast Arkansas, southeast Missouri, western Kentucky and Tennessee, northern of Mississippi, and northwest Alabama. At 11 a.m. EDT (1500 UTC), the Joint Typhoon Warning Center noted, âSatellite imagery depicts an elongated low level circulation center partially obscured by deep convection [wind] sheared slightly to the southwest. It is important to note that cyclones can become extratropical and still retain winds of hurricane or tropical storm force. an infrared image of Tropical Storm Kyle was captured by the VIIRS instrument aboard NASA-NOAAâs Suomi NPP satellite. A Storm Surge Warning is in effect for High Island, Texas to the mouth of the Mississippi River. Surrounding that area were cloud top temperatures were as cold as minus 70 degrees Fahrenheit (minus 56.6. degrees Celsius). Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. All of those areas were generating heavy rain, but within a couple of hours, they diminished. 26 Nov 2020 Originally published 26 Nov 2020. On the 24th, as it neared the northern Gulf Coast, Marco continued to weaken and slow down as high pressure to the east built westward, blocking Marcoâs path and forcing the cyclone to turn westward. At 8 a.m. EDT Monday, August 31 (3 p.m. Tuesday Korea Standard Time), Maysak was about 110 miles south-southwest of Kadena Air Force Base on the island of Okinawa, according to the U.S. Joint Typhoon Warning Center, JTWC, which reported that Maysak was packing 1-minute sustained winds of 125 mph, the equivalent of a Category 3 hurricane. Using the Worldview Application at NASAâs Goddard Space Flight Center, Greenbelt, Md. Typhoon Higos was the first No.8 to be signalled this year by Hong Kong in August. It is a marginal sea of the Pacific Ocean. The center of circulation just made landfall near the mouth of the Mississippi at 6:00 pm CDT on Monday the 24th with sustained winds reported at 40 mph by NHC before being shunted westward back over open water and weakening further. Moderate-to-strong easterly to northeasterly vertical wind shear will likely prevent Iselle from strengthening over the next couple of days. The estimated minimum central pressure is 1001 millibars. NASA infrared imagery shows wind shear continued to batter Tropical Storm Iselle in the Eastern Pacific Ocean for the second day. Lauraâs Status on Aug. 26, 2020 at 2 p.m. EDT Â. NOAAâs National Hurricane Center (NHC) reported at 2 p.m. EDT (1800 UTC), the eye of Hurricane Laura was located near latitude 27.3 degrees north and longitude 92.5 degrees west. That is about 200 miles (20 km) south-southeast of Lake Charles, Louisiana. NHC said, âShortly after the release of the previous advisory, microwave imagery from a WindSat overpass showed no indication of a well-defined center near Hernan’s estimated location. 21) Temporary Closure Message of U.S. Consulate General Osaka-Kobe, Japan; News. ISSUED: August 25, 2020 10:20 AM ET. Nearby Tropical Storm Iselle is expected to begin weakening on Friday, and the system is forecast to degenerate into a remnant low-pressure area on Saturday. Heavy rain, dangerous storm surge, isolated tornadoes and hurricane-force sustained winds are expected. Aug. 04, 2020 – NASA Infrared Imagery Shows Hagupit Nearing Landfall in China NASA’s Aqua satellite provided a look at Typhoon Hagupit as it was nearing landfall in southeastern China. Using the Worldview application at NASAâs Goddard Space Flight Center in Greenbelt, Md., an animation was created of Lauraâs track from Puerto Rico to Louisiana. A wind gust to 128 mph was reported at the Lake Charles Regional Airport. That is because infrared data provides temperature information, and the strongest thunderstorms that reach highest into the atmosphere have the coldest cloud top temperatures. Stronger gusts are possible within thunderstorms. At 11 a.m. EDT (1500 UTC) on Aug. 28, NOAAâs Weather Prediction Center (WPC) noted the center of Tropical Depression Laura was located near latitude 36.6 north, longitude 90.5 west. Despite this, northerly wind shear, drier air and some land interaction initially weakened the storm slightly as it paralleled the south coast of Cuba. Tropical Depression 14E formed in the Eastern Pacific Ocean on Aug. 26 by 11 a.m. EDT (1500 UTC). Wind shear occurs when winds at different levels of the atmosphere push against the rotating cylinder of winds, weakening the rotation by pushing it apart at different levels. Many NASA assets were used to provide forecasters with information to incorporate into their analysis of Hurricane Laura. Kyle is the eleventh tropical storm of the Atlantic Ocean hurricane Season. In addition, tornadoes are possible today and tonight over parts of Louisiana, Arkansas, and western Mississippi.â. Tropical cyclones are made up of hundreds of thunderstorms, and infrared data can show where the strongest storms are located. The latest minimum central pressure estimated from reconnaissance aircraft data is 952 millibars. 2. Maysakâs center is expected to pass just west of Okinawa within 24 hours. (Image credit: NASA Worldview) Iselle is expected to begin weakening late this weekend. At 2 a.m. EDT (0600 UTC) on Aug. 27, Doppler radar images indicated that the eye of Hurricane Laura made landfall at the coast near Cameron, Louisiana, near latitude 29.8 degrees north and longitude 93.3 degrees west. Manila, Philippines, August 3, 2012, 19:36 — The death toll from typhoon “Gener” (international codename: “Saola”) rose to 39 while the cost of damage to agriculture and infrastructure reached P240 million as of Friday morning [August 3], the National Disaster Risk Reduction and Management Council (NDRRMC) said. Little change in strength is forecast during the next couple of days. Laura is moving toward the north near 15 mph (24 kph) and this motion should continue through the day. Rockefeller Wildlife Refuge to Intracoastal City, LA between 10 and 15 feet. NASAâs Terra satellite captured visible imagery as Tropical Storm Bavi made landfall in northwestern North Korea and moved inland. By 11 a.m. EDT, first light visible satellite imagery reveals that Hernan remains a sheared tropical cyclone with most of the deep convection confined to the western semicircle. Tropical cyclones are like rotating cylinders of winds. 8) – July 9, 2018; Alert: Typhoon Cimaron (Typhoon No. to be held on 19 august 2020 Reference is made to the notice of the annual general meeting of Man King Holdings Limited (the "Company" ) dated 20 July 2020 in relation to the annual general meeting (the "AGM" ) scheduled to be convened at Unit D, 10/F, Skyline Tower, 18 Tong Mi Road, Mongkok, Kowloon, Hong Kong on 19 August 2020 at 11:00 a.m.. National Hurricane Center (NHC) Hurricane Specialist Andrew Latto noted in the 11 a.m. EDT discussion, âIselle consists of a rather ragged looking area of deep convection being sheared to the southwest of a partially exposed low-level center. This rainfall will cause widespread flash and urban flooding, small streams and creeks to overflow their banks, and minor to moderate freshwater river flooding. At the time of this GPM overpass, Lauraâs maximum sustained winds were still reported at 100 mph by the National Hurricane Center, the equivalent of a category 2 hurricane.GPM data is archived at https://pps.gsfc.nasa.gov/, Text by Steve Lang, Jacob Reed (NASA Goddard Space Flight Center) On Aug. 25 at 11:35 p.m. EDT (Aug. 26 at 0335 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA’s Aqua satellite revealed the most powerful thunderstorms were around Lauraâs center where cloud top temperatures were as cold as minus 80 degrees Fahrenheit (minus 62.2 Celsius). For updated forecasts, visit: www.nhc.noaa.gov, By Rob Gutro MODIS found the powerful thunderstorms that developed were as cold as or colder than minus 80 degrees Fahrenheit (minus 62.2 degrees Celsius) near Maysakâs center. Beginning as a tropical depression on July 31 in the South China Sea, Sinlaku was the fifth storm of the 2020 Pacific typhoon season. Surrounding that area were cloud top temperatures were as cold as minus 70 degrees Fahrenheit (minus 56.6. degrees Celsius). The estimated minimum central pressure is 1006 millibars. For the entire story click this link: https://disasters.nasa.gov/hurricane-laura-2020/terra-misr-used-visualize-cloud-top-heights-hurricane-laura-3d. Maximum sustained winds have increased to near 60 mph (95 kph) with higher gusts. Strong storms with cloud top temperatures as cold as minus 70 degrees Fahrenheit (minus 56.6. degrees Celsius) surrounded the center and were generating large amounts of rain. Hurricane-force winds extend outward up to 70 miles (110 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km). In general, wind shear is a measure of how the speed and direction of winds change with altitude. NASA-NOAAâs Suomi NPP satellite also caught a nighttime image of Laura just after landfall. Aug. 02, 2020 – NASA Catches Tropical Storm Sinlaku’s Vietnam Landfall NASA’s Aqua satellite passed over Tropical Storm Sinlaku shortly after it made landfall around 2 a.m. EDT (0600 UTC) on Aug. 2 in northern Vietnam.
