King the Preparedness Dog

Winter Storm

  • Snow forms when water vapor in the atmosphere freezes into ice crystals.
  • Snow is a form of precipitation; other forms of precipitation are rain, hail and sleet.
  • Light and fluffy snow is often called ‘powder’.
  • Heavy snowfalls are often called ‘snowstorms’.
  • Snowstorms with high winds are often called ‘blizzards’.
  • Snow reflects a high level of ultraviolet radiation and can cause snow blindness (photokeratitis). Sunglasses, goggles and other eye protection help absorb/reflect the ultraviolet rays.
  • A number of winter sports rely on snow, including skiing and snowboarding.
  • Recreational activities such as snowball fights, tobogganing and making snowmen are also popular in the snow.
  • Skis, sleds and snowmobiles are useful transport options through snow.
  • Snow can lower visibility, making driving conditions dangerous.
  • The highest snowfall ever recorded in a one year period was 31.1 meters (1224 inches) in Mount Rainier, Washington State, United States, between February 19, 1971 and February 18, 1972.
  • The lowest temperature in the United States was -79.8°F (-62.1C) at Prospect Creek Camp in the Endicott Mountains of northern Alaska on January 23, 1971.
  • Outside from Alaska, the coldest U.S. temperature was -69.7°F (56.5°C) in Rogers Pass, Montana, January 20, 1954.
  • One storm, from February 13-19, 1959, dumped 189 inches of snow at Mt. Shasta Ski Bowl, California.
  • The greatest snowfall in 24 hours in the United States was at Silver Lake, Colorado, on April 14-15, 1921: 75.8 inches.
  • The most snow in the United States in one month—390 inches (32.5 feet) fell at Tamarack, California, in January 1911.
  • In the winter of 1971-72, 93.5 feet (1,122 inches) of snow fell at the Rainier Paradise Ranger Station in the state of Washington.
  • In the Antarctic, there is a 30-30-30 rule. When the temperature is 30 below, and the wind is 30 miles per hour, a person can live only 30 minutes outside.
  • During the winter, you often hear the term “wind chill.” Wind combined with cold air makes your body feel even colder than the actual temperature. You get that feeling when you get out of the pool or ocean in the summer. In winter, wind chill can be dangerous.
  • When the outside temperature is zero degrees and the wind speed is 20 miles per hour; the wind chill makes it feel like 22 degrees below zero. Exposed skin will freeze in less than 30 minutes.
