Recommendation
Safest morning window: 7–10 AM EDT, when it is sunny and precipitation chances are 2–5%; limit heat exposure and ensure the vehicle is prepared. Evening: no clearly safe evening driving window is forecast—avoid nonessential travel from 6 PM through midnight, especially 8–9 PM and 10 PM–midnight when thunderstorms are likely. If travel is unavoidable, delay until a break in storms, drive slowly, use headlights, and do not drive through flooded roadways.
