Recommendation
If you must drive, the safest morning window is early, around 7:00-8:00 AM EDT, before storms intensify and before the Flood Watch begins at 10 AM. In the evening, conditions remain hazardous with likely thunderstorms; the least-bad window is later, around 11:00 PM-midnight EDT as precipitation probability drops toward 55%. Avoid driving during the 10 AM-10 PM heavy-rain and flooding period; never drive through flooded roadways.
