The interactive map above shows the coronavirus restriction level of all California counties as of Nov. 16. Those in the purple tier will be subject to a 10 p.m. to 5 a.m. curfew starting Saturday Nov. 21 under a new limited curfew order issued on Thursday Nov. 19 and running until Dec. 21 unless modified.

The order, which is designed to combat a surge in COVID-19 cases, requires all non-essential work, movement and gatherings stop during the curfew period. It will be in effect in all Bay Area counties except San Francisco, San Mateo and Marin.
