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. Maysak is forecast to move northwest and pass just to the west of Okinawa Island on Aug. 31 as it tracks north. ByÂ Rob Gutro At NASAâs Goddard Space Flight Center in Greenbelt, Md. Maximum sustained winds were near 30 mph (45 kph) with higher gusts. However, the warm waters were offset by the effects of southwesterly wind shear, which were to become a major inhibiting factor as Marco moved through the Gulf of Mexico. 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. Visible image from NASA’s Terra satellite of Typhoon Maysak on August 31, 2020, after the storm had moved past Japan’s Ryukyu Islands (outlined). It is important to note that cyclones can become extratropical and still retain winds of hurricane or tropical storm force. Kyle is the eleventh tropical storm of the Atlantic Ocean hurricane Season. NHC warned about dangerous storm surge, heavy rainfall, hurricane-force winds and isolated tornadoes. ISSUED: August 25, 2020 10:20 AM ET. For updated forecasts, visit: www.nhc.noaa.gov, ByÂ Rob GutroÂ 8) – July 9, 2018; Alert: Typhoon Cimaron (Typhoon No. 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. Tropical Depression Lauraâs Status on Aug. 28. Additional weakening is forecast, and Hernan is expected to degenerate to a remnant low-pressure area tonight.Â The remnants are expected to dissipate on Saturday. 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. Sea Rim State Park, TX to Johnson Bayou, LA including Sabine Lake is between 10 and 15 feet. NHC noted late on Aug. 27, that Hernan appeared poorly organized, and despite a burst of strength, the storm weakened to a depression. NASAâs Goddard Space Flight Center. NASA-NOAA’s Suomi NPP satellite provided a night-time image of the development of Tropical Storm Kyle off the coast of New England. Infrared instruments enable satellites to gather imagery on storms at night because they read temperature. On Aug. 28 at 2:40 a.m. EDT (0640 UTC), the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASAâs Terra satellite captured an infrared image of cloud top temperatures in Iselle. Issued On: DL 006 Ticket Stock. 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). At the time, it was located near latitude 41.6 degrees north and longitude 125.8 degrees east, about 249 nautical miles north of Inchon, South Korea. 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 1006 millibars. The estimated minimum central pressure is 997 millibars. NASA satellites keep a watchful eye over the Earth day and night to help scientists and forecasters. 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. That is about 20 miles (30 km) north of Fort Polk, Louisiana. Typhoon Higos was the first No.8 to be signalled this year by Hong Kong in August. 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. NASAâs Terra satellite is one in a fleet of NASA satellites that provide data for hurricane research. Laura made landfall as strong category 4 hurricane near Cameron, Louisiana shortly after midnight on August 27, 2020, bringing extreme rainfall, storm surge, and winds up to 150 mph. The Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA’s Terra satellite captured a visible image of Tropical Storm Bavi on Aug. 27. Marco originated from a tropical easterly wave that was moving from the central to the western Caribbean. NHC said, âThe combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline.Â The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide. By Saturday, 1 to 3 inches of rain is forecast from the central and southern Appalachians to the Mid-Atlantic States. On Aug. 25, NOAAâs National Hurricane Center (NHC) posted several watches and warnings on major Hurricane Laura. 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. Marco remained over warm open water as it passed through the Yucatan Straight and into the Gulf of Mexico on the afternoon of the 22nd. The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard Suomi NPP provided days of infrared nighttime imagery of the now former hurricane Laura. All of those areas were generating heavy rain, but within a couple of hours, they diminished. Major Disaster Declaration declared on December 9, 2020. 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. The tropical depression northeast of extreme Northern Luzon entered the Philippine Area of Responsibility (PAR) at 4 am on Thursday, August 13. The estimated minimum central pressure is 1001 millibars. Little change in strength is expected today, but a gradual weakening trend should begin tonight. Incident Period: August 23, 2020 - August 27, 2020. A new animation of nighttime imagery from NASA-NOAAâs Suomi NPP satellite followed the path of former Hurricane Laura from its landfall in southwestern Louisiana to its movement over the Mississippi Valley. Iselle is far from land at about 560 miles (900 km) southwest of the southern tip of Baja California, Mexico. As it approached Puerto Rico on the 22nd, Laura was still unorganized, and although the wind shear abated, Laura was now inhibited by its close proximity to land. A Storm Surge Warning is in effect for High Island, Texas to the mouth of the Mississippi River. California BOND FIRE (FM-5383-CA) Incident Period: December 3, 2020 and continuing. The latest minimum central pressure estimated from reconnaissance aircraft data is 952 millibars. Rockefeller Wildlife Refuge to Intracoastal City, LA between 10 and 15 feet. Laura is moving toward the northwest near 16 mph (26 kph). Nighttime imagery from NASA-NOAAâs Suomi NPP satellite revealed the Eastern Pacific Oceanâs Tropical Storm Hernan along the coast of western Mexico. Reports from an Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds have increased to near 140 mph (220 kph) with higher gusts.Â Laura is an extremely dangerous category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale.Â Some additional strengthening is possible this afternoon, and Laura is forecast to remain a category 4 hurricane through landfall tonight.Â Rapid weakening is expected after Laura makes over land. NASA-NOAAâs Suomi NPP satellite also caught a nighttime image of Laura just after landfall. The storm is expected to make landfall in southern South Korea and will start to become extra-tropical. 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. For much more on this story, click this link:Â Â GPM Flies Over Cat. 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. This rainfall will cause widespread flash and urban flooding, small streams and creeks to overflow their banks, and minor to moderate freshwater river flooding. By this time, Laura was very near to the coast of western Louisiana where it then made landfall near Cameron, Louisiana at 1:00 a.m. CDT at the same 150 mph intensity. Astronaut Chris Cassidy aboard the International Space Station took several photos of Hurricane Laura as it neared the Gulf coast on Aug. 26, 2020 at 3:27 p.m. EDT. As Laura tracks across the eastern U.S., it is generating heavy rain and has triggered watches. Tropical Depression 06W (Gener) JMA Warning and Weather Summary (WWJP27): 2020-08-09 00Z, 06Z, 12Z, 18Z ... Typhoon Bavi (09W, Igme) JMA Warning and Weather Summary (WWJP27): A Tropical Storm Warning is in effect from Sargent, Texas to San Luis Pass and for areas east of Intracoastal City, Louisiana to the mouth of the Mississippi River. In general, wind shear is a measure of how the speed and direction of winds change with altitude. Kyle is forecast to become post-tropical on Sunday. 2. 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. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km).Â An observing site in Alexandria, Louisiana, recently reported a wind gust to 74 mph (119 kph).The estimated minimum central pressure is 970 millibars. NASA infrared imagery shows wind shear continued to batter Tropical Storm Iselle in the Eastern Pacific Ocean for the second day. 8) – July 9, 2018; Alert: Typhoon Cimaron (Typhoon No. The depression was moving toward the east-northeast near 20 mph (31 km/h) and this motion is expected to continue as Laura tracks along and south of the Ohio Valley through tonight. At 1.30 am on 19 August 2020, the Hong Kong Observatory raised the typhoon no. 5, also … The National Hurricane Center (NHC) noted at 5 a.m. EDT (0900 UTC), the center of Tropical Storm Kyle was located near latitude 38.7 degrees north and longitude 68.0 degrees west. On the forecast track, Laura will move northward across western and northern Louisiana through this afternoon. That is because infrared data provides temperature information, and the strongest thunderstorms that reach highest into the atmosphere have the coldest cloud top temperatures. Tropical Depression 14E formed in the Eastern Pacific Ocean on Aug. 26 by 11 a.m. EDT (1500 UTC). By Steve Lang NASA infrared imagery shows that newly formed Tropical Storm Iselle is already battling for its life under wind shear. That is about 619 miles south of Kadena Air Base, Okinawa Island, Japan. Typhoon Higos roundup As Typhoon Higos is moving away from Hong Kong, the Hong Kong Observatory issued the Strong Wind Signal No. 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. It is estimated that Laura maintained hurricane intensity for the next 10 hours as it moved northward into northern Louisiana. Each level needs to be stacked on top each other vertically in order for the storm to maintain strength or intensify. 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. Despite this, northerly wind shear, drier air and some land interaction initially weakened the storm slightly as it paralleled the south coast of Cuba. Animating Hurricane Lauraâs Path to Landfall. The estimated minimum central pressure is 1001 millibars. It was moving to the north-northeast. 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). Surrounding that area were cloud top temperatures were as cold as minus 70 degrees Fahrenheit (minus 56.6. degrees Celsius). However, there was a hint of a small vortex well to the northeast. On Aug. 3 at 1:41 p.m. EDT (1741 UTC) NASA’s Aqua satellite analyzed Typhoon Hagupit less than 2 hours before landfall in China. Typhoon Maysak continued to move through the Northwestern Pacific and was closing in on Japanâs Okinawa Island when NASAâs Terra satellite obtained a visible image of the storm. The center of Laura is forecast to move over Arkansas tonight, the mid-Mississippi Valley on Friday, and the Mid-Atlantic States on Saturday. NASA brings together technology, science, and unique global Earth observations to provide societal benefits and strengthen our nation. Using the Worldview Application at NASAâs Goddard Space Flight Center, Greenbelt, Md.

The JTWC then issued a Tropical Cyclone Formation Alert(TCFA) for the embryonic system just hours later while convection began to gradually o… Stronger gusts are possible within thunderstorms. Through Friday, forecasters expect Laura to produce the following rainfall totals: Across portions of Louisiana, Mississippi, across Arkansas: 6 to 12 inches with isolated totals of 18 inches. Maysakâs center is expected to pass just west of Okinawa within 24 hours. Maysakâs eye is not expected to go over the island, but pass just west of it. 4 Hurricane Laura Twice As It Makes Landfall in Louisiana, Text by Owen Kelley, Jacob Reed, Joe Munchak (NASA GSFC) Tropical cyclones are made up of hundreds of thunderstorms, and infrared data can show where the strongest storms are located. The photos also revealed a clear eye surrounded by powerful thunderstorms. IMERG satellite-based rain estimates can be compared to that from a National Weather Service ground radar.Â Such good detection of large rain features in real time would be impossible if the IMERG algorithm merely reported the precipitation observed by the periodic overflights of various agencies’ satellites.Â Instead, what the IMERG algorithm does is “morph” high-quality satellite observations along the direction of the steering winds to deliver information about rain at times and places where such satellite overflights did not occur.Â Information morphing is particularly important over the majority of the world’s surface that lacks ground-radar coverage. One to 2 inches, with isolated 4-inch totalsÂ are possible over southern parts of Louisiana, Mississippi, and Alabama. Wind shear was pushing the rest of the storms to the west. Typhoon Hagupit, known in the Philippines as Severe Tropical Storm Dindo, was a Category 1 typhoon that heavily impacted Eastern China and South Korea in August 2020. GPM overpass visualization by Alex Kekesi (NASA Goddard Scientific Visualization Studio) The heaviest rainfall totals due to Marco were just offshore and along the coast of the Florida Panhandle and reached up to 225 mm (~9 inches, shown in dark red) while a good portion of the Florida Panhandle is estimated to have received at least 75 to 100 mm (~3 to 4 inches, shown in bright green and yellow). Twelve hours later it strengthened to a tropical storm and was renamed Hernan. Heavy rain, dangerous storm surge, isolated tornadoes and hurricane-force sustained winds are expected. North Korean leader Kim Jong Un visited a western coastal area hit by Typhoon Bavi — which made landfall near Pyongyang on Thursday — and said the country was “fortunate” to … The storm was elongated and strong storms appeared to be pushed southwest of the center from vertical wind shear. Maysak is moving to the west-southwest and has maximum sustained winds near 35 knots (40 mph). NASA’s Goddard Space Flight Center. NOAA’s National Hurricane Center (NHC) noted, “The low-level center of Kyle continues to be exposed to the west of the deep convection, as strong westerly shear prevails. At 11 a.m. EDT (1500 UTC), the center of Tropical Depression Hernan was located near latitude 23.4 north, longitude 109.1 west, about 60 miles (100 km) northeast of the southern tip of Baja California, Mexico. In addition, tornadoes are possible today and tonight over parts of Louisiana, Arkansas, and western Mississippi.â. Moderate-to-strong easterly to northeasterly vertical wind shear will likely prevent Iselle from strengthening over the next couple of days. NASA-NOAAâs Suomi NPP satellite passed over Hurricane Laura soon after it made landfall in southwestern Louisiana around 2 a.m. EDT on Aug. 27. 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. Despite forming a day later, Marco was the first system to make landfall on the Gulf Coast. Cloud tops have cooled significantly over the past 6 hours as the convection has continued to consolidate.â. 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. an infrared image of Tropical Storm Kyle was captured by the VIIRS instrument aboard NASA-NOAAâs Suomi NPP satellite. Imagery showed the eye of the storm appeared filled with high clouds, as powerful bands of thunderstorm circled it. Typhoon Bavi – Bulletin 1. For more than five decades, NASA has used the vantage point of space to understand and explore our home planet, improve lives and safeguard our future. The NASA / JAXA GPM Core Observatory satellite flew over Hurricane Laura shortly before it made landfall at 10:00pm CTÂ on Wednesday, August 26th, then again at 7:42am CT on Thursday, August 27th when it was over land, capturing data on precipitation within the storm. However, no fatalities had been reported. A Tropical Storm Warning is in effect for High Island, Texas to the mouth of the Mississippi River. Little change in strength is forecast during the next couple of days. Aspects of Japan’s geography, not least its position, make it susceptible to typhoons. Tropical Depression 10W formed during the early morning hours on Aug. 28 and quickly organized and strengthened into a tropical storm. For updated forecasts, visit: www.nhc.noaa.gov, By Rob Gutro Although the satellite appearance is not that impressive, the circulation is well intact as indicated by a recent ASCAT overpass that reveals that the initial intensity remains 40 knots (45 mph).”, The image was created using NASA’s Worldview application. Tropical-storm-force winds have reached the coast of Louisiana and an observing site at Eugene Island recently measured sustained winds of 39 mph (63 kph) and a gust to 64 mph (104 kph). 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.Â That is about 200 miles (20 km) south-southeast of Lake Charles, Louisiana. However, the rainfall due to Marco is evidenced by its north-south orientation and generally extends from the west-central Caribbean up through the Yucatan Strait and the eastern Gulf of Mexico and into the Florida Panhandle. Iselle continues to produce deep convection and strong thunderstorms near the center and on its west side. Hernan was moving toward the north-northwest near 5 mph (7 kph). an animation was created of nighttime imagery from Aug. 23 to 28, 2020 (0000 UTC) that showed the track of Hurricane Laura from the landfall and movement Â from southwestern Louisiana to the Mississippi Valley. For the entire story click this link:Â https://disasters.nasa.gov/hurricane-laura-2020/terra-misr-used-visualize-cloud-top-heights-hurricane-laura-3d. 20) August 22, 2018; Alert: Typhoon Jebi (Typhoon No. By the weekend, Hernan is expected to absorb nearby Tropical Storm Iselle. It brought strong winds and was raised to No.9, the second-highest tier in the weather system. According to the National Hurricane Center (NHC), TD #14 reached tropical storm intensity on the night of the 21st and named Marco. Typhoon Haiyan (Yolanda) Final Periodic Monitoring Report November 2013 to August 2014 Format Evaluation and Lessons Learned Source. Applicable to Travel On: Delta / Delta Connection A View from the International Space Station. Laura made landfall as a powerful Category 4 hurricane along the Louisiana coast. etzhar August 26, 2020 6:05 pm at 6:05 pm IMERG surface rainfall accumulations were compiled for the period 22 to 27 August 2020 for the southeastern U.S., Gulf of Mexico, the northwest Caribbean and adjacent regions. NOAAâs WPC provided a look at the hazards that Tropical Depression Laura is expected to bring along its path toward the Atlantic Ocean over the next 2 days:Â “Expect 1 to 3 inches, with isolated 5-inch totals from western and central Kentucky and Tennessee into northern Alabama and Mississippi. Infrared Data Provides a Temperature Check. IMERG rainfall visualization by Owen Kelley, Jason WestÂ (NASA Precipitation Processing System). 21) September 2, 2018; Alert: Typhoon Jebi (Typhoon No. However, as it neared the Leeward Isles on the 21st, it finally reached minimum tropical storm intensity and named Laura. The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard Suomi NPP provided a visible imagery of Laura from its birth in the Atlantic. Bands of thunderstorms from the south were spiraling into the low-level center. 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. Precipitation cloud-top heights from the DPR (highlighted in blue, indicating frozen precipitation) show Laura still had the overall structure of a powerful hurricane, as evidenced by both the symmetry of the outer rain bands that still wrap completely around the storm, as well as the residual structure of a strong core near the center containing elements of very heavy rain (shown in pink). The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard Suomi NPP captured a nighttime image. It was moving to the north-northwest and had maximum sustained winds near 100 knots (115 mph/185 kph). Hurricane-force winds and damaging wind gusts are also expected to spread well inland into portions of eastern Texas and western Louisiana this morning. At 5 a.m. EDT on Aug. 27, the National Hurricane Center noted, âAlthough Hernan is a sheared tropical cyclone, another strong burst of deep convection with cloud tops of minus 83 to minus 86 degrees Celsius has developed near and south through west of the center.â NASA research has shown that cloud tops that cold have the ability to generate heavy rainfall. Tropical Storm Sinlaku was a weak but deadly tropical cyclone that impacted Vietnam, Thailand and Laos in August 2020.
