A rare “high risk” warning for flash flooding has been issued in Texas and Louisiana as the states brace for up to 9 inches of rain in the next 24 hours.

“The high risk area has seen over 600% of their normal rainfall for the past two weeks alone,” the National Oceanic and Atmospheric Administration warned, and the flash flooding could be life-threatening.

“High risk” days account for just 4% of days, but they are responsible for more than one-third of flooding deaths, according to the Weather Prediction Center.
