Understanding cold weather alerts
Warning of cold weather: Exercise caution. When seasonably cold air temperatures or wind chill values—but not exceptionally severe ones—are anticipated or happening, a cold weather advisory is issued. When you and your loved ones go outside, make sure you cover any exposed skin and wear suitable clothing.
Warning: Extreme cold: Act now! When dangerously low air temperatures or wind chill values are predicted or already occurring, an extreme cold warning is issued. Avoid venturing outside if there is an extreme cold warning in effect. Make sure at least one other person is aware of your whereabouts, wear layers if you must go outside, and cover any exposed skin. When you reach your destination safely, update them.
Be ready for extreme cold watch. When extremely low air temperatures or wind chill values are possible, an extreme cold watch is issued. As with a warning, change your plans so that you don’t spend the coldest hours of the day outside. Update your winter survival gear and make sure your car has at least half a tank of gas left.
