Recommendation
Avoid driving during the flash flood warning and flood watch period, especially 7:00 AM to 12:00 PM. If travel is essential in the morning, avoid low-lying roads and underpasses, and never drive through flooded roadways. Safer driving windows are mid-afternoon to evening, particularly 1:00 PM to 6:00 PM when skies clear and roads should be drier, and again from 6:00 PM to 10:00 PM as conditions remain calm and dry with light winds.
