SACRAMENTO, Calif. (KSEE/KGPE) — Gov. Gavin Newsom is expected to announce Thursday a new regional “stay-at-home” order for some California counties.

Sources tell’s Ashley Zavala that the regional stay-at-home order will be based on a region’s available hospital capacity.

While retail will still be allowed to operate, capacity will be reduced to 20%.

Those regions affected will have 48 hours to make the necessary adjustments.

Newsom warned Monday that he would have to impose new restrictions if the trends continue.

Wednesday, California reported more than 20,000 new cases. That’s the most ever for a single day.

Newsom is staying at home after three of his children were exposed to the virus. He has already imposed restrictions, including a nighttime curfew on 51 of the state’s 58 counties. That covers almost all of California’s nearly 40 million residents.
