At around 3:30 p.m., radar showed thunderstorms producing heavy rain across the warned area, and flash flooding was ongoing or expected to begin shortly thereafter, the National Weather Service said.
Between 1.5-2 inches of rain had fallen by about 7 p.m. Law enforcement reported flash flooding across the area.
What to do in flooded roads
Turn around and don’t drown when encountering flooded roads, the NWS advised. They said most flood deaths happen in vehicles.
The rushing water also could cause hazards to be aware of. Rock slides or debris flows were expected across rural roads, along with flash flooding in small creeks, streams and ditches.
