Recommendation
Avoid driving during the morning, especially in or near the warned area; never drive through floodwater. A safer morning slot is not supported by this forecast. If travel is necessary, consider 1:00–5:00 PM EDT, after the watch ends and rain chances drop. Evening travel around 6:00–9:00 PM EDT also looks favorable; check for lingering road closures or flooding first.
