Tag: Winter Storms/Extreme Cold
Winter storms have the capability to completely immobilize large areas of a state, and possibly several states simultaneously. Thus, winter weather warnings, watches, and advisories are issued by the National Weather Service (NWS) for relatively large geographic areas, rather than for one specific county or a small group of counties.
Planning and preparing can help you manage the impact of a winter storm and keep you and your family safe.
To assess your vulnerability to the threat of a Winter Storm or Extreme Cold event to your family and property, perform an assessment to determine if you have knowledge of, are prepared and/or have a plan by answering certain questions.
Winter storms can range from a normal snow over a few hours to a blizzard with blinding, wind-driven snow that lasts for several days. Many winter storms bring dangerously low temperatures and, sometimes, strong winds, icing, sleet, and freezing rain. Moreover, serious health problems can result from prolonged exposure to the cold such as hypothermia and frostbite.
Extreme Cold Notifications issued by the National Weather Service include frost advisories, freeze, and hard freeze watches and warnings. Wind chill notifications are also used, but are only defined for temperatures at or below 50°F and wind speeds above 3 mph.
A winter storm is an event in which varieties of precipitation are formed that only occur at low temperatures, such as snow or sleet, or a rainstorm where ground temperatures are low enough to allow ice to form (i.e. freezing rain).
