Alameda County sent out a red flag warning for East Bay hills and interior valleys in an AC Alert on Sunday.

The warning, issued by the National Weather Service, will be in effect from Sunday at 11 p.m. to Monday at 8 p.m., in response to low humidity and “anticipated gusty offshore winds.” Due to the weather conditions, there is an increased risk of fires spreading rapidly through the area, which includes the Berkeley Hills.

The report emphasizes that outdoor burning is discouraged and recommends signing up for AC Alert, which is the Alameda County emergency notification service, leaving phones turned on and reviewing evacuation zones.
