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 curfew from 10 p.m. to 5 a.m. 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.
