ACROSS TEXAS — A large stretch from southwest to northeast Texas, which includes San Antonio, Austin and Dallas, is under a flash flood watch as Tropical Storm Pamela makes landfall in Mexico.

The flash flood watch lasts through Thursday evening for most counties affected, with the biggest threat occurring Wednesday night along the Interstate 35 corridor. There is some risk beginning as early as midday Wednesday, and rainfall totals are expected to be between 2 and 5 inches, with 5 to 7 inches possible in some isolated areas, according to the National Weather Service.

The area of heaviest rainfall follows a "plume of moisture" from a low pressure system in the Upper Midwest United States to Tropical Storm Pamela in Mexico, according to NWS.
