While no heat or fire weather advisories are currently in effect, the National Weather Service (NWS) is monitoring conditions that could impact the Bay Area and Sonoma Valley later this week.
- Heat Risk: Temperatures are expected to remain above normal through Wednesday, with widespread Moderate HeatRisk. This means heat-related illness is possible, especially for older adults, infants, outdoor workers, and people with chronic health conditions. Even well-acclimated individuals may feel uncomfortable during peak heating hours.
- Fire Weather: The NWS notes the potential for dry thunderstorms on Thursday and Friday, which could produce lightning with little rainfall. If this risk increases, a Fire Weather Watch or Red Flag Warning may be issued as soon as Tuesday. Gusty outflow winds combined with dry fuels could cause new or existing fires to spread quickly.
Preparedness Tips
Since September is National Preparedness Month, now is a great time to take simple steps to stay safe in the event of extreme heat, wildfires, or unplanned power outages:
- Make a plan: Review your household emergency plan and talk about evacuation routes.
- Pack a go-kit: Include essentials like water, medications, important documents, flashlights, and chargers.
- Stay informed: Sign up for local alerts and check the National Weather Service website for the latest forecasts.
- Be power ready: Unplanned outages can happen during extreme weather. Keep backup batteries charged and know how to safely store perishable food.
