The Difference Between a Snowstorm and a Blizzard

The biggest snowstorm of the year is expected to blast the northeastern US on Tuesday. In New York City, on top of the significant snow totals that have been forecast, a blizzard warning is in effect.

Different than a typical winter storm, a blizzard is characterized more by wind speeds and reduced visibility than the amount of snow it produces. According to the NWS, the three main factors for blizzard conditions are:

  • Wind – Sustained winds or frequent gusts of 35mph or higher.
  • Visibility – Falling and/or blowing snow that reduces visibility to ¼ mile or less.
  • Time – High winds and reduced visibility must prevail for at least 3 hours.

These conditions heighten the risk of power outages and often produce whiteout conditions on roadways, making travel extremely dangerous.  Stay Safe!
