Winter Storm Watch vs Warning: Snow, Ice, Wind, and Travel Risk
What winter storm watches and warnings mean, how they differ from advisories, and why ice and wind can be more disruptive than snowfall totals alone.
The alert ladder
Winter weather advisories, watches, and warnings describe increasing confidence or impact. Local criteria vary because a disruptive snow amount in one region may be routine in another.
Read the details. The headline may be snow, ice, blowing snow, sleet, or a mix.
Why totals are not everything
Four inches of dry snow on a quiet Sunday is different from two inches of snow and ice during rush hour. Wind, timing, temperature, road treatment, and power line icing all matter.
Ice can create severe travel and power problems even when accumulation sounds small.
What to do during a watch
Check supplies, charge devices, prepare backup heat safely, refill prescriptions if needed, and adjust travel plans before roads worsen.
If you rely on electricity for medical equipment, review backup options before the storm.
What to do during a warning
Avoid unnecessary travel. If travel is unavoidable, carry warm clothing, water, food, phone power, scraper, shovel, and emergency supplies.
Keep generators outside and far from windows or doors. Carbon monoxide is a major winter storm danger.
