Torrential rain is inundating southeastern Texas, forcing schools to cancel classes and closing numerous highways around Houston.

Numerous Southeast Texas counties remained under a Flood Watch — meaning flooding was possible — through Friday evening. At best, the rainfall would slow exiting floodwater, the weather service said. At worst, it would cause more flooding.

A line of storms continues to move across Cypress, the Woodlands, and Beaumont Thursday morning as some neighborhoods brace for flash flooding.
