More than six inches of rain fell in the San Antonio region overnight, surpassing the city’s average rainfall for June and July combined.

The abrupt closure comes after the city experienced record-breaking rainfall in the morning hours on Thursday. Between 3 and 8 inches of rain occurred in Bexar County, according to the National Weather Service. The heavy rains blanketed the region, causing power outages, high-water rescues and at least four fatalities.

Ongoing storms and downpours moving east across the South will increase the flood threat for major cities across Louisiana and Arkansas on Friday and into Saturday.

At least four people are dead, and several others were rescued after heavy rainfall and flash flooding inundated San Antonio, Texas.
