Teeth chattering, bone chilling — people like Benita were waiting for the bus, all bundled up.

“I have everything prepared,” she said. “I make sure I have my gloves, my coat, sweater, whatever I need. I have on about three layers.”

How about that 70 degree weather in recent weeks?

“I don’t know, it just throws you off,” Benita said. “It’s finally winter. I’m not going to complain.”

Others said they were willing to deal with the freezing temps as long as Old Man Winter didn’t bring any snow.

“I put my earmuffs on and my gloves on, but we’ll survive,” said Judy. “It’s been a mild winter. So far, so good. No snow anyway.”

The Code Blue was declared until 3 p.m. in Philadelphia.

City officials were urging residents to check on elderly neighbors.

The Project Home hotline (215-232-1984) was open to report any homeless person out in the cold and get them inside.
