Gov. Gavin Newsom and California Department of Public Health officials on Thursday announced a month-long overnight stay-at-home order that will apply to California counties with the state's highest rates of COVID-19 transmission.
Starting Saturday, Nov. 21, the limited stay-at-home order will be in effect between 10 p.m. and 5 a.m. for counties in the "purple" tier of the state's reopening guidelines, which indicates the most widespread coronavirus risk. The order mandates that nonessential work, movement and gatherings stop during these hours.
The order will remain in effect until 5 a.m. on Monday, Dec. 21. Currently, it will apply to the six Bay Area counties now in the purple tier:
- Alameda
- Contra Costa
- Solano
- Napa
- Santa Clara
- Sonoma
The only Bay Area counties not in the purple tier – Marin, San Francisco and San Mateo – are currently in the red tier, which represents the second-most widespread risk.
On Monday, Newsom announced that a whopping 41 counties – representing 94% of the state's population – would be designated under the purple tier, rollbacks he likened to "pulling the emergency brake" on reopenings amid a rapid uptick in COVID-19 cases and hospitalizations.
