The United States has an average of one hundred snowstorms every year. These storms usually produce snow for two to five days.(4)It has snowed in almost every part of the country at one time or another, although it is much less common in the southern states.In the far northern part of the country, Americans have battled deep snow and powerful winds. Such things are common in the states of South and North Dakota. Minnesota also got hit. Temperatures were far below freezing. And the wind has made the snow blow so hard and fast that it was sometimes impossible to see. In the northeastern United States, people are facing another kind of winter problem. Last week, the New England states were hit by a terrible ice storm.(5)Hundreds of thousands of people were forced to leave their homes because of power outages.
    Around the nation, there are reports of at least ten weather related deaths. And winter is just beginning. Snow and other winter weather cause hundreds of deaths in the United States every year. Traffic accidents on snowy or icy roads cause many of them. Other deaths are the result of severe cold or heart attacks from extreme physical activity like clearing snow. Winter storms can be dangerous.(6)People should stay in their homes during snow storms. They should take short rests while clearing snow. And people should have supplies like extra blankets, water, food and special power devices before a storm hits.
