Understanding Snow Squalls and Blizzards: Key Differences and Safety Tips

Blizzards are defined by sustained winds of at least 35 mph and visibility of a quarter-mile or less for at least three hours.

Snow squalls are fast-moving, short-duration bursts of heavy snow and strong winds, often leading to whiteout conditions.

Snow Squall Warnings were first implemented by the National Weather Service in 2018, similar to severe thunderstorm or tornado warnings.

Travel is highly discouraged during both blizzards and snow squalls due to the increased risk of accidents and pileups.

Stopping distances on snowy or icy roads can be significantly longer; a car traveling at 40 mph may require nearly five times the stopping distance on ice compared to a dry road.

Snow squalls can cause flash freeze conditions on roadways, exacerbating the hazard. Why this matters: Knowing the specific risks associated with each type of storm allows individuals to make informed decisions about travel and safety.

Monitor weather forecasts and warnings.

If travel is necessary, ensure your vehicle is properly equipped for winter conditions.
