Deadly flooding devastates San Antonio as more heavy rainfall impacts Indiana, Tennessee

San Antonio, Texas, is in recovery mode after being struck by historic and deadly flash flooding on Thursday. The torrential downpours led to widespread inundation, claiming at least 10 lives and necessitating numerous high-water rescues throughout the city.

LAFAYETTE, La. – Ongoing storms and downpours moving east across the South will increase the flood threat for major cities across Louisiana and Arkansas into the early weekend.

The rainfall comes after as much as 8" of precipitation led to flooding in the heart of the Lone Star State, with nearly a dozen fatalities reported.

San Antonio was especially hard hit, with at least 70 water rescues taking place on Thursday.

"Our hearts are with the families of those we’ve lost to this week’s flash floods and the families who continue searching for their loved ones," Mayor Ron Nirenberg said in a statement.

San Antonio recorded 6.11 inches of rain, making it the second-wettest June day on record in 12 years. The half-foot of rain also nearly doubles the previous daily record of 3.26 inches set back in 1973 and made Thursday the 10th-wettest day ever recorded at San Antonio International Airport. 

HOW TO WATCH FOX WEATHER

As storms shift to the east, the flooding risk moves with it into Louisiana, Arkansas and southwestern Tennessee into Saturday. A Level 2 out of 4 flash flood risk is present in these regions into the early weekend.

The wet weather played havoc with the annual Bonnaroo Music Festival held in Tennessee.

Event organizers reported a several-hour delay for ticketholders and encouraged everyone to seek shelter until the storms moved through.

The heaviest rainfall appeared to have occurred over southern Indiana, where Flash Flood Warnings and even a Flash Flood Emergency was issued.

First responders reported attending to several water rescues as 3-5" of rainfall covered some roadways.

Flood Watches also extended from parts of Louisiana back into Texas.

Severe storms will also continue to be possible as well, with the main threat being damaging wind gusts. However, a brief tornado cannot be ruled out.
