Recommendation
Do not drive during peak thunderstorm periods. If travel is essential, restrict driving to early morning 6-7 AM (before rain intensifies) or very early next morning after midnight when activity decreases. Absolutely avoid driving 1 PM to 10 PM when thunderstorms and heaviest rainfall are most likely. Monitor local flood warnings and flash flood alerts before any trip.
