SAN ANTONIO (AP) — Heavy rains in San Antonio rapidly flooded roads, swept away submerged cars and sent some people scrambling up trees to escape fast-rising waters Thursday while firefighters made dozens of rescues across the nation’s seventh-largest city. At least four people died and two were still missing, authorities said.

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

Months worth of rain on Wednesday night led to multiple water rescues in San Antonio, where at least four people were killed by floodwaters.
