Key Factors
- 01 Areas of fog reported from 7am–10am, continuing as patchy fog from 11am–12pm (07:00–12:00 local time), with very high relative humidity (93%).
- 02 Temperatures are cool in the morning (43–47°F), which can worsen fog persistence and visibility.
- 03 Wind picks up during the day (SW 8–12 mph around 1pm–5pm), which can add some difficulty for smaller or high-profile vehicles, though not a major risk driver by itself.
- 04 Evening/night: slight chance of rain showers from 8pm–2am (hourly probability peaks around 15%), and daily forecast adds patchy fog after 2am—both can reduce tire traction and sightlines.

Recommendation
Safer to drive in the morning before the densest fog begins to spread and before mid-morning patchiness: 12:00–1:00pm. For the evening, avoid the wet/fog-prone period: 6:00–7:00pm (before 8:00pm when rain-showers begin).
