Summer is technically over, but you wouldn’t know it in the Bay Area.

A heat advisory from the National Weather Service (NWS) has been extended through 7 p.m. today, warning of triple-digit temperatures in parts of the Bay Area.

NWS says to expect coastal temperatures in the middle 80s to lower 90s “with widespread 90s across the interior and around the San Francisco Bay Shoreline.” Temperatures of 100 to 104 degrees will be possible “in the warmest valley and interior locations.”

The forecast includes temperatures ranging from 91 in San Francisco; 100 in Santa Rosa; and 101 in places like Concord, Walnut Creek, and San Jose.

This coincides with a red flag warning throughout much of the Bay Area due to wildfire risks, as well as an intentional PG&E blackout in some parts of the North Bay in hopes of mitigating fire risks.

On top of fire risks, heat itself can be dangerous. The Center For Disease Control (CDC) warns that “extreme heat often results in the highest number of annual deaths among all weather-related hazards,” with extreme heat defined as any two-day or longer period with high humidity and temperatures of more than 90 degrees.

The CDC further advises that on hot days, simple precautions may become critical, including “Find air conditioning, avoid strenuous activities, check on family members and neighbors, watch for heat cramps, heat exhaustion, and heat stroke, [and] never leave people or pets in a closed car.”
