GREEN BAY, WI -- People throughout northeast Wisconsin are now preparing for sub-zero temperatures.
On Sunday, neighbors were busy staying on top of shoveling before all the fresh snow hardens in the anticipated deep freeze.
Ice and frostbite are now becoming an even bigger concern.
"Plenty of snowfalls like this," says Green Bay resident Ryan Beaumont, shovel in hand. "They come and go, and some years are worse than others."
Beaumont was spending part of his day helping shovel his neighbor's driveway, and walkway.
"Just to get the driveway cleaned off, and sidewalks cleared," explained Beaumont, "just so it doesn't freeze."
Having dealt with his share of Wisconsin winters, Beaumont says he knows to get to the snow before it's virtually impossible to move.
"The ends of the driveway usually are the ones that are the heaviest from the snowfall," explains Beaumont. "And, if those freeze, it's very difficult to move even with a snowblower. So, if you can get to it before it happens, all the better."
When it gets this cold, highway safety experts say pavement that seems clear can really be dangerous.
"The driving surfaces can change is just a matter of minutes," says Mark Kantola, of WisDOT.
With hypothermia and frostbite setting in faster in sub-zero temperatures, Kantola says staying warm is critical for drivers stuck in the ditch.
"Stay in your car. But, if you're low on gas, start the car intermittently," says Kantola, "every 5 or 10 minutes."
If you're stuck in the snow, experts say it's also important to avoid carbon monoxide poisoning by keeping it out of your tailpipe.
"You need to be aware of that," says Kantola. "Maybe check your pipe, and make sure your exhaust is coming out good."
