Tropical Storm Harvey continued to hit southeastern Texas on Sunday with “catastrophic flooding” in Houston, forcing residents to flee to their roofs and higher ground as officials respond to thousands of 911 calls for rescues in the “unprecedented” event. Several hundred people arrived at the George R. Brown Convention Center in downtown Houston, which officials are using as a shelter as flood waters have inundated much of the city.

The Red Cross is prepared to manage 1,000 people at the convention center.
