Winter storms can bring snow, sleet, and freezing rain across the entire United States and its territories. Thousands of people are injured or killed every year in traffic accidents related to slippery roads from winter storms. Winter storms create a higher risk of car accidents, hypothermia, frostbite, carbon monoxide poisoning, and heart attacks from overexertion.
Sleet: Rain that turns to into pellets before reaching the ground. Sleet also causes moisture on roads to freeze and become slippery.
Freezing Rain: Rain that freezes when it hits the ground, creating a coating of ice on roads, walkways, trees, and powerlines.
Black Ice: Patchy ice on roadways that cannot be easily seen. It is often clear (not white) with the black road surface visible underneath. It is most prevalent during the early morning hours, especially after snow has melted & had a chance to refreeze over night.
Avalanche: A rapid flow of snow down a hill or mountainside.
