Southeast Texas has been hit hard with severe rain as heavy storms continue to sweep through the area, with some areas reporting up to 10 inches of rainfall. Flash flood warnings are in effect across the region as emergency crews brace for additional severe weather.

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.

The situation turned dire overnight as a half-foot or more of rainfall led to fast-moving floodwaters in parts of San Antonio and neighboring communities.
