A "Blizzard Warning" is issued by the National Weather Service when severe winter weather is expected. This warning indicates that strong winds of 35 mph or more, combined with heavy snowfall, will create dangerous conditions. Visibility may drop to less than a quarter mile, making travel extremely hazardous. During a blizzard, conditions can change rapidly, leading to life-threatening situations. It is important for individuals to stay indoors, keep warm, and avoid unnecessary travel. Those in affected areas should prepare by stocking up on essential supplies and staying informed through local weather updates and alerts from the National Weather Service.
