Winter is coming: Freeze warning in effect throughout Bay Area counties

A freeze warning is in effect throughout the Bay Area from Sunday night to Wednesday morning, according to the National Weather Service.

Sonoma County issued a county freeze warning over the upcoming weather conditions and ask its residents to limit their outdoor time due to the increasing risks of hypothermia and frostbite. The county also asks unhoused people to seek warming shelters as soon as possible, as they are on a first-come, first-served basis.
