Recommendation
Drive early: the safest morning window is roughly 7:00-10:00 AM EDT when rain chances are only 11-19%. In the evening, conditions are poor throughout, but the least-bad slot is about 6:00-7:00 PM before storm coverage peaks at 85% after 8 PM; if possible, postpone evening travel. Never drive through flooded roadways, allow extra following distance, use headlights, and check for flash flood warnings before departing.
