A forecast calling for cold and rainy conditions over the next few days has prompted officials in Santa Cruz County to open emergency shelters in Santa Cruz and Watsonville.

The National Weather Service said a short period of rain will move through the entire Bay Area on Saturday.

At the same time, temperatures were expected to start falling overnight Friday and into Saturday, with the coldest period expected Sunday and Monday.

During that time, inland valleys can expect lows in the mid 20s to low 30s while coastal and San Francisco Bay temperatures will see lows from the upper 30s to mid 40s.

To help project vulnerable populations from the frigid temperatures, a shelter at the Depot Park at 119 Center St. in Santa Cruz will be open through Monday, a shelter at the Veterans Memorial Building at 846 Front St. in Santa Cruz will be open Sunday and Monday and a shelter at the Veterans Memorial Building at 215 E. Beach St. in Watsonville will be open through Monday.

All shelters will operate from 8 p.m. to 8 a.m. And people can start lining up at 7 p.m.

“Beds will be offered on a first-come, first-served basis, with preference for people with disabilities and those experiencing significant health/safety risk sleeping outdoors,” Santa Cruz County officials said in a news release.

People will be given cots, blankets and food, and pets are allowed if they are leashed and can be kept under voice control.

People who are unhoused and can’t make it to a shelter should sleep in tents or cars if they can and should wear multiple layers of clothing and use sleeping bags and blankets.
