The upgrade to Orange means that Yolo County can further relax some guidelines on indoor businesses. Places like places of worship, theaters and restaurants can open to 50 percent capacity in the Orange tier.

County leaders still stressed caution as the region reopens further.

“We run the risk of undoing our hard-earned progress if we let down our guard now,” said Yolo County Health Officer Dr. Aimee Sisson in a statement on the move into the Orange tier.

One of the biggest changes when a county reaches the Orange tier is arguably to professional sports. According to state guidelines, outdoor sports venues can reopen to 20 percent capacity.

Restrictions on outdoor live events will also be relaxed after April 1, per state guidelines announced earlier in the month.

Yolo was also joined by Lassen, Marin, San Francisco, Santa Clara and Trinity counties in moving to the Orange tier. Nevada and Stanislaus counties, which have been lingering in the most-restrictive Purple tier, were upgraded to the less-restrictive Red (substantial) COVID-19 alert tier on Tuesday.

One eight counties remain in the Purple tier.
