Stay-at-home order issued for San Francisco Bay Area, ahead of state mandate - CNBC

San Francisco Bay Area health officials announced on Friday that they would implement California's new stay-at-home order early, even though they haven't reached the state's threshold triggering the new restrictions.

If the remaining ICU capacity in a region falls below 15%, it will trigger a three-week stay-at-home order, Newsom said.

While none of the regions met the ICU threshold to trigger the stay-at-home order on Thursday, Newsom warned that every area was projected to drop below 15% ICU capacity at some point in December.

Health officers for the counties of Alameda, Contra Costa, Marin, San Francisco and Santa Clara as well as the city of Berkeley made the joint announcement on Friday, saying they would implement the order early.

However, the announcement did not include some counties in the Bay Area region, as defined by the state's order, including Santa Cruz, Monterey, Napa, San Mateo, Solano, Sonoma.

Breed in a tweet after Newsom's announcement on Thursday said that while the order didn't apply to San Francisco yet, the county was "looking closely at local data and talking to our neighboring counties about next steps."
