Flash flood warnings, explained
The National Weather Service in Fort Worth issued a flash flood warning for counties along the I-20 corridor on Monday as North Texas experiences its first substantial rainfall of the summer.
Some areas in Tarrant and Dallas counties received 8-12 inches as of Monday morning, according to the National Weather Service.
What counts as a flash flood?
A flash flood can occur within minutes or a few hours of excessive rainfall and take generally less than six hours to develop. According to the weather service, flash floods are raging torrents after heavy rains that sweep everything before them.
What is ‘Turn Around Don’t Drown’?
During a flash flood, people walking or driving through flood waters should move immediately to higher ground.
Turn Around Don’t Drown was created as a safety initiative by the National Oceanic and Atmospheric Administration. Six inches of fast-moving flood water can knock over an adult and twelve inches of rushing water can carry away most cars. Trucks and SUVs can be carried away by two feet of rushing water.
How can I stay safe if I have to drive?
Rainfall can impact roadway visibility, pavement friction and lane obstruction, increasing the risk of accidents and delaying traffic.
Between Sunday evening to early Monday morning, MedStar responded to 23 crashes including one call about a vehicle in flooded water.
