24 hours after making landfall, Harvey’s rainfall prompts flash flood emergencies in Houston

One 24-hour period down, several more to go.

That will be the lasting impact of (formerly) Hurricane Harvey, which has since weakened to a tropical storm as it lashes the eastern half of Texas.

Though Harvey made landfall late Friday night as a major Category 4 hurricane (with sustained winds of 130 mph), the brutally strong winds are only half of the battle for the Lone Star State.

Between Friday and Saturday, over a foot of rain has fallen from Austin to Houston, and unfortunately, more is on the way.

Flash flood emergencies (a type of weather alert that is more dire than flash flood warnings) have been issued for the Houston area as numerous high water rescues are reported in the area. Below is a roundup of some of the local storm reports from throughout Texas due to Harvey.
