As of Tuesday, Dec. 8, California only has one of its 58 counties in the orange (moderate tier) and three counties in the red (substantial tier) according to the state’s four-tier coronavirus tracking system.

The state is no longer doing a weekly update and tier assignments may occur any day of the week and may occur more than once a week, officials have said.
