A meteorologist says Bexar County has the most number of deaths from flash flooding in the nation.

SAN ANTONIO — New video shows the devastation of the deadly flash floods in San Antonio that took the lives of 13 people on June 12.

KENS 5 obtained video that shows cars being swept away at Beitel Creek.

A meteorologist says Bexar County has the most number of deaths from flash flooding in the nation. 

Over the last 28 years, South Central Texas has had 147 flash flood fatalities, with 47 of those deaths happening in Bexar County.

On June 12, 15 vehicles were washed away by rushing flood water near Beitel Creek and 410 after heavy rainfall.

“It’s pretty heavy rainfall over a very metropolitan area, very densely populated area,” said Jason Runyen, forecaster with the National Weather Service out of Austin, San Antonio. 

Runyen says the intense rainfall rates set records here in San Antonio and contributed to the deadly flash flooding.

“San Antonio recorded their highest one hour rainfall on record, dating back to the 1930s. At the international airport, we saw 3.9 inches of rainfall that occurred in only one hour and 6.11 inches of rain that occurred for the whole day,” said Runyen.

Video shows the dangerous conditions drivers faced as they were being carried away by the flood waters.

“Any type of flowing water like that is very dangerous, especially if you’re caught in a vehicle,” said Runyen.

Besides the heavy rainfall, Runyen says other conditions that impact flash flooding is the location where the rains fell.

“So this kind of set up again on the north side of San Antonio, northwest all the way to the northeast side of San Antonio where it’s a little bit more hilly, we have some low water crossings. We have a lot of creeks and storm drainage areas to that area,” said Runyen.

Runyen says for the drivers caught in the flash flooding, it’s too early in the investigations to determine what went wrong.

A total of 13 fatalities occurred on June 12.

Runyen recommends not traveling during days of heavy rain.

“We did have flash flood warnings ongoing for Bear County in that area through much of the night and into the early morning hours,” said Runyen.
