Turn around, don`t drown when encountering flooded roads. Most flood deaths occur in vehicles.
Be especially cautious at night when it is harder to recognize the dangers of flooding.
D.C., Arlington, Alexandria – we are many hours away from the end of the rain.
Probably until at least midnight. A whopping 140 miles more of downpours to go through.
This could bring flooding issues. 2 to 3 inches of rain possible, w/locally more not improbable. @FOX5DC pic.twitter.com/89kJvj6SS8
