Recommendation
Avoid driving during the morning, especially before noon while the Flash Flood Warning (until 10 AM) and Flood Watch (until 12 PM) are active. If you must travel early, wait until after 12:00 PM when rain chances drop sharply and skies become partly sunny. Best morning window is roughly 11 AM-12 PM only if necessary; the safest evening window is 6:00-8:00 PM with clear skies, light winds, and 0% precipitation. Never drive through flooded roads—turn around, don't drown.
