Recommendation
If you must drive, the least unfavorable window is 7:00-8:00 AM, before heavier rain becomes established, and the best evening window is 6:00-7:00 PM, though rain is still likely. Avoid unnecessary travel during periods of steadier rain and be prepared for wet roads and lower visibility.
