Key Factors
- 01 Continuous rain from morning through night with precipitation probabilities peaking at 96-97% (9am-10am and 7pm)
- 02 Slight chance of thunderstorms after 5pm which could bring locally heavy downpours
- 03 100% relative humidity all day increases the risk of misted windows and wet-road spray
- 04 Overnight north wind gusts up to 22 mph could cause minor crosswinds
- 05 No fog, ice, snow, or active weather alerts; temperatures stay in the 60s, so no freezing risk
- 06 Visibility data is not provided, adding some uncertainty

Recommendation
Drive with headlights on, increase following distance, and slow down on wet roads all day. If possible, favor lighter-rain windows: mid-day around 1pm (chance of light rain, ~35%) in the morning/afternoon, and late evening after 11pm (~27%). Avoid the heaviest periods around 9-10am and 6-8pm, and watch for thunderstorms after 5pm.
