The National Weather Service on Saturday morning added areas in the North Bay to a Red Flag Warning originally issued for just for parts of the East Bay this weekend.
There will be critical fire conditions Saturday night through early Monday morning for the North Bay coast and the East Bay hills and interior valleys, according to the National Weather Service.
The Red Flag Warning will be in effect from 9 p.m. Saturday to 9 p.m. Monday.
Hot and dry temperatures will produce critical fire conditions and will increase heat-related risks, according to the National Weather Service.
