Homeless shelters around the Bay Area are pulling out their emergency beds with freeze warnings and frost advisories expected.

J. C. Orton runs the Berkeley Emergency Storm Shelter.  The facility has room for 50 people, but it can only afford to operate about 30 nights a year, including Wednesday night.  “We've got to pick the nights very carefully," Orton said Wednesday. "Tonight is going to be 34 degrees windchill factor -- that's cold enough to warrant us opening."

In downtown Berkeley, a homeless woman named Lauren said she has sometimes stayed at the emergency shelter but mostly sleeps in a doorway. “It’s hard, because the concrete is cold," she said. "Other than that, I can pretty much stand it. Cardboard blocks the wind really, really good though.”
 
Forecasters expect the frosty weather to continue through the beginning of  the week of January 14.
