With dry, desiccating offshore winds developing in the San Francisco Bay Area during a severe early-autumn heat wave, officials warned Friday that the risk of wildfire sparks and spread is high. The National Weather Service issued a red flag warning just before 11 a.

More than 200 October record highs have been set and extreme temperatures are poised to persist for several more days.

An excessive heat warning has been extended for much of the Bay Area through late Friday night, as a late season heat wave continues to bring hot temperatures to the region, some of which have been record-breaking.

An unprecedented October heat wave has enveloped the West, with record-setting temperatures from California to Colorado.

The end of this early autumn San Francisco Bay Area heat wave keeps getting pushed back. When the scorching weather first arrived Monday, forecasts indicated temperatures would drop by the end of the week, but the latest forecast shows Saturday and Sunday will still be hot, especially across inland areas, with widespread temperatures in the 90s.

“All of the heat warnings and advisories — they’ve all been extended,” NWS meteorologist Nicole Sarment said. “We’ve got a tiny disturbance (Friday), and the main threat from that will be an increase in winds, and there’s some degree of moisture. But this isn’t over yet.”
