A blizzard warning is issued by meteorological agencies when severe winter weather is expected. This warning indicates that strong winds, heavy snowfall, and low visibility will occur, making travel dangerous. Typically, a blizzard is defined by sustained winds of 35 mph or more, along with significant snowfall and reduced visibility of less than a quarter mile for at least three hours. When a blizzard warning is in effect, it is important for individuals to stay informed through local weather updates and to prepare for potential disruptions. People are advised to avoid unnecessary travel, stock up on essential supplies, and have a plan in case of power outages during the storm.
