With chilly, wet weather expected to stick around this week and bring near-freezing temperatures to the Bay Area, Santa Clara County is opening warming centers at public libraries to give people a respite from the cold.

Several of the centers opened today, Jan. 9, with more slated to open tomorrow. The warming centers include four in Palo Alto and two in Los Altos.

Light rain is expected into Wednesday, with more substantial precipitation this weekend. Temperatures are forecast to dip into the 30s at night, according to a county press release.

Cold weather raises the risk of hypothermia and frostbite, with older people, young children, those with chronic medical conditions and unsheltered people at higher risk, according to the county.

Hypothermia is a medical emergency and its symptoms include confusion, dizziness, exhaustion, severe shivering, clumsiness and lack of coordination, slurred speech and mumbling, the county said. If someone is observed exhibiting signs of hypothermia, call 911.
