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.

Thirteen vehicles were swept away early Thursday morning on the northeast side near Northeast Loop 410 and Beitel Creek. At least four people are dead and three are missing in San Antonio, Texas, after floodwaters swept 13 vehicles away early Thursday morning.
