Key Factors
- 01 Rain is forecast essentially all day (hourly shows rain/rain likely from 8am through at least 10pm, with high PoP 70–97% much of the time), leading to slick roads and longer stopping distances.
- 02 Very high humidity (near 100% all day) suggests a higher chance of poor visibility in heavier rain and spray, though visibility data is not provided.
- 03 Slight chance of thunderstorms after about 5pm (daily forecast) through before 1am; storms can cause sudden heavier downpours and localized hazards.
- 04 Night period includes north wind gusts up to 22 mph (daily), which can make driving less stable especially during heavier rain, though sustained winds are modest.

Recommendation
If you must drive, allow extra following distance and reduce speed. Morning: safest window is 07:00–08:00 (lowest listed PoP at 28%, though light rain is still possible); avoid 08:00–12:00 when PoP is 79–97% with steady rain. Evening: safest window is 22:00–00:00 (PoP drops to ~57% then 27% by 23:00); avoid roughly 17:00–21:00 due to steady rain and the forecast slight thunderstorm chance after ~17:00.
