Winter storms can bring extreme cold, heavy snowfall, strong winds, and icy conditions. When a winter storm warning is issued, it means hazardous weather is expected or already occurring. Understanding these warnings, how to prepare, and how to stay safe is crucial. This guide will explain everything you need to know about winter storm warnings, their impact, and safety measures.
What is a Winter Storm Warning?
Definition and Meaning
A winter storm warning is an alert issued by the National Weather Service (NWS) when severe winter weather conditions, such as heavy snow, ice accumulation, or strong winds, are imminent or already happening. Unlike a winter storm watch, which signals the possibility of severe conditions, a warning means dangerous weather is actively affecting an area.
When is a Winter Storm Warning Issued?
Meteorologists issue a winter storm warning when specific criteria are met, such as:
- Snowfall of 6 inches or more within 12 hours
- Ice accumulation of at least 0.25 inches
- Sustained winds over 35 mph, creating blizzard-like conditions
Types of Winter Storm Warnings
Blizzard Warning
A blizzard warning is issued when winds exceed 35 mph and visibility is reduced to less than 1/4 mile due to blowing snow for at least three hours.
Ice Storm Warning
An ice storm warning means significant ice accumulation is expected, making roads and sidewalks extremely dangerous.
Snow Squall Warning
A snow squall warning is for intense but short bursts of heavy snowfall combined with strong winds, creating sudden whiteout conditions.
