GPM Overpass of Hurricane Laura 8/27/20
After crossing western Cuba, Tropical Storm Laura emerged into the Gulf of Mexico where warm water, low wind shear and a moist environment made conditions ideal for intensification. As it made its way through the Gulf of Mexico Laura strengthened - from a category 1 hurricane with sustained winds of 75 mph on the morning of Tuesday August 25th, to a powerful category 4 storm, with sustained winds of 150 mph on the evening of Wednesday August 26th - an increase of 75 mph in just 36 hours. At this point Laura was nearing the coast of western Louisiana, and made landfall near Cameron, Louisiana
GPM Overpass of Hurricane Laura 8/26/20 10:00pm CT
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. 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 NASA / JAXA GPM Core Observatory satellite flew over Hurricane Laura shortly before it made landfall at 10:00pm CT on Wednesday, August 26th, then again at 7:42am CT on Thursday, August 27th
Hurricane Laura on August 27, 2020
Update on August 28, 2020: During its approach to Louisiana, Hurricane Laura dramatically intensified from Category 2 to 4 (105 mph to 150 mph) between at 1AM and 7PM Central Time (CDT) on August 26, 2020. In the updated movie below, the precipitation falling from Laura is shown through 10:30PM CDT, August 27, as estimated by NASA's IMERG algorithm.

On August 26, Laura became the first North Atlantic hurricane to reach "major hurricane" status this year, meaning that it reached category 3 on the Saffir-Simpson hurricane-intensity scale
Hurricane Isaias Impacts the US East Coast
From July 29 to August 5, 2020, NASA’s IMERG algorithm observed tropical storm Isaias’ rainfall over the Caribbean and large parts of the Eastern US. This animation shows the IMERG rain rates in green shading as Isaias tracked from the tropical Atlantic into the Caribbean, then northward along the Atlantic coast and into New England. The yellow line shows the location of Isaias' low-pressure center, as tracked by the National Hurricane Center and smoothed in time here for the animation.
IMERG Hurricane Hanna 7-27-20 cropped
Hanna formed from a westward propagating tropical easterly wave that entered the southeast corner of the Gulf of Mexico on Tuesday July 21st. The wave provided a focus for shower and thunderstorm activity, which then led to the formation of an area of low pressure over the central Gulf of Mexico. The National Hurricane Center (NHC) found that this low had developed a closed circulation by the evening of Wednesday July 22nd, making it Tropical Depression #8. Over the next 24 hours, the depression slowly organized and intensified over the central Gulf before reaching tropical storm intensity on
