None of the other Bay Area counties are included in the alert.
Meteorologists explain expected strong winds and very dry conditions this weekend is the concern, considering the unseasonably warm and dry conditions northern and central California experienced this week, meaning larger swaths of dry grasses in the Sacramento Valley region could support relatively large or rapid fire spread.
A three-alarm fire broke out in Solano County Saturday morning near the Carquinez Bridge in Vallejo. Fire crews say it has been contained.
