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
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.
