Overview
- Strong offshore winds reaching up to 80 mph on Mount St. Helena over the weekend have eased, with gusts dropping below advisory levels by Tuesday morning.
- Temperatures surged into the 70s and 80s across the Bay Area on Monday, with inland valleys experiencing unseasonably warm conditions.
- Despite low humidity levels of 15–25%, fire danger remains below critical thresholds due to lingering moisture in vegetation from winter rains.
- April rainfall was only 25–30% of average, accelerating vegetation drying and signaling an early shift toward fire season in the North Bay and East Bay regions.
- The return of onshore flow and a marine layer is expected to cool coastal areas, but the Bay Area will remain in a dry, stable weather pattern under high pressure through midweek.
