Staff at homeless shelters in the Twin Cities likely will be working round-the-clock shifts by this weekend, when temperatures in the Twin Cities will bottom out in the double digits below zero.
The worst will come Saturday, when the high temperature is forecast to be 6 below. Before that, though, there's a brief respite. Remember, warm is relative. Wednesday's high is expected to be 6 degrees above zero; Thursday's forecast called for 15 and Friday for 3. New Year's Eve and New Year's Day, well, 0 and 1 degree.
So, how do people who have to be outside, either by necessity or circumstance, deal with the cold?
Mail carriers will indeed deliver mail at temperatures of 15 below, said Darla Swanson, communications manager for the U.S. Postal Service. The carriers' employer reminds them regularly to dress properly, stay dry, keep extra clothing in the vehicle in case they become wet and know the signs and symptoms of cold stress.
The same "safety first" credo applies for workers who are out battling ice buildup on the roads or cutting brush in the extreme cold, said Kevin Gutknecht, communications director for the Minnesota Department of Transportation (MnDOT).
Crews were working in various locations for MnDOT on Tuesday, Gutknecht said.
Outdoor work in the winter takes longer. That's just the way it is, and MnDOT is OK with that, he said. Most outdoor work crews are experienced and know when it's time to take a break to warm up.
"We want to make sure whatever we do, we want to do it safely," Gutknecht said.
