As Harvey's rains push northwards into Kentucky and the nation's northeast corridor, new photos reveal the extent of flooding the record-breaking storm left behind in the Houston region.

Satellite images released by NASA and San Francisco-based startup Planet show once-green neighborhoods, farm areas and golf courses inundated by brown flood waters as Harvey's clouds finally dissipated Thursday.

Harvey — which made landfall in southern Texas as a category 4 storm on August 25 — dumped more than 30 inches of rain on portions of Houston and eastern Texas over a four-day period. Between the increased urban development and already saturated soils, the unprecedented waters had nowhere to go.

Texas authorities now say the 1-in-1000-year flood event damaged or destroyed more than 156,000 homes, drove thousands to local shelters, and left at least 39 people dead.
