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.

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
