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.

Deadly flooding struck Texas on Wednesday night after more than a month's worth of rain fell in just hours, turning roads into rivers that submerged vehicles and made travel impossible.

At least four people were killed in San Antonio as heavy rain lashed Eastern Texas and sent flash floods sweeping through the city overnight, officials said on Thursday.
