With subfreezing temperatures expected for the next few days, the Detroit Rescue Mission plans to keep its shelters open so long as it remains this cold. Normally, their shelters are open from 5PM to 8PM. However, so long as temperatures remain below freezing, the shelters will not close.

Crain's Detroit Business: As of early afternoon, the nonprofit was at capacity at all three of its shelters, both those for men and a third for women and children in Detroit. But it has added additional floor mattresses and chairs at the shelters in anticipation of more people arriving, [Rescue Mission CEO Chad] Audi said.

Already, its Midtown Detroit shelter for men is 20 people above its capacity of 80. The extra guests will increase Detroit Rescue Mission's daily operating costs at the shelters by about a third, Audi said. That will equate to roughly $20 a day per person for food, showers and laundry facilities, up from about $15.

The mission says it stockpiles supplies in the event of extreme cold weather and will not turn away anyone seeking shelter.
