With a blast of cold weather about to hit York County starting tonight, the York Rescue Mission said it's ready to take in additional homeless people if needed.

But not all homeless people like to spend time in a shelter because they feel confined and, instead, take their chances on the streets, said Rescue Mission spokeswoman Dianne Smeigh.

The mission saw only a slight increase in the number of homeless seeking shelter when temperatures dipped below freezing last week. There was a greater increase in the number of people who went to the mission for a meal, she said.

The mission operates a shelter that is always open and allows people to stay between one to five days.

"If (the shelter) gets overflowed, we'll put mattresses down in the chapel," she said. "We don't want anyone on the street."

Leslie Brengle, spokeswoman for the York/Adams chapter of the Red Cross, said there are no plans at this time to open warming shelters.

Extreme cold: Severe sub-freezing temperatures will start tonight when the thermometer is expected to drop to 0 but a wind chill will make it feel like 17 below, according to the National Weather Service.

Tuesday and Wednesday won't be much better. The high on Tuesday will be 12 with a nighttime low of 3. The temperature will increase on Wednesday, when a high of 24 and low of 18 is expected, the weather service says.
