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.

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.

Witnesses told police that they saw 4-5 vehicles being swept away by the high water. Crews are working to recover all the unaccounted-for vehicles.
