Weather Tidbits: Winter Weather Alerts

Today’s weather tidbits topic is about winter weather alerts. There is a winter storm watch, a winter storm warning, and a winter weather advisory, but there is also a blizzard warning that we will discuss as well. A winter storm warning means you need to take action as a winter storm is imminent or occurring. A winter storm watch means that a winter storm is possible and that you need to be prepared for wintry conditions. A winter weather advisory means that some wintry weather is expected, but it’s not going to be as severe. A blizzard warning means that winds are sustained at 35+ mph or there are frequent wind gusts of 35+ mph and there is reduced visibility down to ¼ mile due to falling snow or blowing snow. A winter storm warning is issued for northern Delmarva when 5 or more inches of snow is expected in a 12 hour period or if  ¼ inch of ice is expected. The criteria is slightly different for southern Delmarva. A winter storm warning is issued for southern Delmarva (including Salisbury) if 4 or more inches of snow is expected in a 12 hour period or if  ¼ inch of ice is expected. And a winter weather advisory is issued when at least 1-2 inches of snow is expected or if a glaze of ice is expected on the sidewalks or roads.
