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!
