Overview

  • A red flag warning remains in effect through 8 p.m. Monday across Northern California, from Redding to Modesto, due to gusty winds and low humidity.
  • Wind gusts are forecast to reach 35–45 mph in valleys, up to 55 mph in higher elevations, and gale-force along the coastline, heightening wildfire risks.
  • PG&E has stated it does not currently plan preemptive power shutoffs, though residents are urged to monitor updates and practice fire safety measures.
  • Forecasters anticipate a warming and drying trend midweek, with inland temperatures rising 5–10°F, potentially reaching the 90s in areas like Concord and Fairfield.
  • Coastal regions will remain cooler due to lingering onshore flows, while grass-dominated areas in the North Bay, East Bay, and Sacramento Valley face heightened fire vulnerability.
