Impacts: Travel remains very hazardous. Roads remain snow-covered, and the blowing snow will cause reduced visibilities and deeper snowdrifts on untreated roads. Wednesday night and Thursday morning. Frostbite will be possible on exposed skin in only around 10 minutes, with hypothermia possible with extended time outdoors.

Precautionary, preparedness actions: A winter storm warning for heavy snow means severe winter weather conditions are expected or occurring. Significant amounts of snow are forecast that will make travel dangerous. If you must travel, keep an extra flashlight, food, water and cellphone in your vehicle in case of an emergency.

A wind chill advisory means that very cold air and strong winds will combine to generate low wind chills. This will result in frostbite and lead to hypothermia if precautions are not taken. If you must venture outdoors, make sure you wear a hat and gloves and minimize as much exposed skin as possible.
