Recommendation
Prefer driving in the morning, such as 8–11 AM EDT, before storms develop. Avoid unnecessary travel from noon through the evening, especially 2–8 PM; if you must drive then, never drive through standing or moving floodwater. No clearly safer evening slot is supported by this forecast; reassess conditions and alerts before traveling.
