Tropical Storm Imelda brings extreme rainfall to Texas •

Last update: September 22nd, 2020 at 12:00 pm

Today’s Image of the Day from NASA Earth Observatory maps the extreme rainfall in southeast Texas from Tropical Storm Imelda.

The system pulled in heat and moisture from the Gulf of Mexico before moving very slowly over Houston and Beaumont, causing damaging flash floods.

The brightest areas on the map represent the highest rainfall amounts, with some places receiving as much as 30 inches from September 17 to September 20, 2019. 

The data comes from the Integrated Multi-Satellite Retrievals for the Global Precipitation Measurement (GPM) mission.
