Impacts: Dangerous conditions for exposed skin. Frostbite can
occur on unprotected skin in as little as 10 to 15 minutes, and
there is risk of hypothermia if proper precautions are not taken.
Precautionary, preparedness actions: 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, gloves and scarf and minimize as
much exposed skin as possible. Bring pets indoors.
