Winter Storms/Extreme Cold – Vulnerability Assessment

119

While the danger from winter weather varies across the U.S., most people are likely to face some type of severe winter weather at some point in their lives. That could mean snow or subfreezing temperatures, as well as strong winds or even ice or heavy rain storms. Winter storms, which often affect northern states, result in extreme cold, downed power lines and blocked roads and highways.

Each year, many people die due to exposure to cold. Add to that number, vehicle accidents and fatalities, fires due to dangerous use of heaters and other winter weather fatalities and you have a significant threat.[1]

  • Threats, such as hypothermia and frostbite, can lead to loss of fingers and toes or cause permanent kidney, pancreas and liver injury and even death. You must prepare properly to avoid these extreme dangers. You also need to know what to do if you see symptoms of these threats.
  • A major winter storm can last for several days and be accompanied by high winds, freezing rain or sleet, heavy snowfall and cold temperatures.
  • People can become trapped at home or in a car, without utilities or other assistance.
  • Attempting to walk for help in a winter storm can be a deadly decision.
  • The aftermath of a winter storm can have an impact on a community or region for days, weeks or even months.
  • Extremely cold temperatures, heavy snow and coastal flooding can cause hazardous conditions and hidden problems.
