Recommendation
Avoid non-essential travel today, especially 10 AM through late night when flooding and severe storms are most likely. Safer windows: early morning 7–9 AM before heavy rain arrives; evening driving is not recommended, but if unavoidable, wait for a lull after midnight as storms wind down before 3 AM. Never drive through flooded roadways.
