AUSTIN (KXAN) — Thursday night’s storm brought so much rainfall it became the second wettest day ever recorded at Austin-Bergstrom International Airport as 8.79 inches fell—most of that in two hours. The rain total obliterated the previous May 26th record of 2.86 inches in 1957.
In another sign of more frequent weather extremes, Thursday night’s rainfall came just seven months after the all-time daily rainfall record was set at ABIA. That was 12.49 inches last Oct. 30, in a storm that claimed several lives in flooding on Dry Creek south of the airport. Two people remain missing in the same area after Friday morning’s flood.
Thursday night’s rainfall is still being evaluated, but is expected to be considered an approximately 1-in-500 year event. The deluge last Oct. 30 was determined to be as much as a 1-in-1,700 year rain event on Dry Creek.
Airport records began during WWII with the establishment of Bergstrom Air Force Base in Del Valle in 1942.
