Recommendation
Avoid nonessential travel during the wettest morning period, especially 8 AM–noon when rain chances are 79–97%. If driving is necessary, the relatively better morning slot is 7–8 AM, though light rain remains possible. For evening travel, the least unfavorable slot is 10–11 PM as rain chances fall to 57%, but roads may still be wet; avoid 5–10 PM when rain is more likely and thunderstorms are possible. Slow down, increase following distance, and use headlights and wipers.
