SAN FRANCISCO (KGO) — A red flag warning was allowed to expire for the Bay Area and Central Coast after gusty offshore winds subsided, the National Weather Service said Saturday afternoon.

While wind speeds decreased, “near-critically dry conditions will remain in place through early next week,” the San Francisco Bay Area Weather Forecast Office said on social media.

Wind gusts in the North Bay Mountains and East Bay Mountains that reached 50 to 60 mph overnight had dropped to 20 to 25 mph by late afternoon, meteorologist Dylan Flynn said.

The red flag threat is determined by a combination of wind speed and humidity, he said.

“We lost one of them – we lost wind speed, that’s good,” Flynn said. “We no longer meet the Red Flag criteria, but we are still flirting with the Red Flag criteria.”

As of 6 p.m., humidity was 28% at San Francisco's official climate station, the San Francisco Mint, 11% in southern Santa Clara County at San Martin Airport and 22% at Napa County Airport, the weather service said.

Strong winds and low humidity continue to create dangerous fire conditions.
