Wind chill advisory: what it means, and its new name
“Wind Chill Advisories are issued when low wind chill temperatures are expected but will not reach local warning criteria. Extremely cold air and strong winds will combine to generate low wind chill readings. If you must venture outdoors, take precautions against frostbite and hypothermia.”

What to do now
- Close off rooms you do not need, stay together in one, and stuff towels into cracks under doors to keep heat in.
- Wear layers: wool, silk or polypropylene underneath, insulation in the middle, a wind-resistant outer layer. Stay dry.
- Never heat your home with a gas stove or oven. Never run generators, grills or camp stoves indoors.
- Hypothermia signs include shivering, confusion, slurred speech and drowsiness. Seek medical attention; a body temperature below 95 degrees is an emergency.

Watch, warning or advisory?
Each in the National Weather Service's own words.
Wind Chill Advisory
“Wind Chill Advisories are issued when low wind chill temperatures are expected but will not reach local warning criteria. Extremely cold air and strong winds will combine to generate low wind chill readings. If you must venture outdoors, take precautions against frostbite and hypothermia.”
Wind Chill Warning
“Wind Chill Warnings are issued for a combination of very cold air and strong winds that will create dangerously low wind chill values. This level of wind chill will result in frostbite and lead to hypothermia if precautions are not taken. Avoid going outdoors and wear warm protective clothing if you must venture outside.”
Wind Chill Watch
“Wind Chill Watches are issued when there is the potential for a combination of extremely cold air and strong winds to create dangerously low wind chill values.”
NWS no longer issues Wind Chill Advisories. On October 1, 2024 it renamed them Cold Weather Advisories (and Wind Chill Warnings became Extreme Cold Warnings), because cold can be dangerous with or without wind. The definitions above are still on weather.gov's winter page; the live box shows today's alerts under the new names.
