Recommendation
If you must drive, the safest window in the morning is before 8:00 AM EDT when precipitation chance is only 19%. There is no safe evening window today — precipitation probability remains above 50% from late afternoon through midnight. Avoid driving after 5 PM EDT when storms intensify significantly. Stay away from low-lying roads and underpasses where water may accumulate.
