[FEB. 13, 2007]  From the National Weather Service, Lincoln:

Hazardous winter weather impacts
  • On average, 44 people in the United States lose their lives each year due to winter storms. This ranks No. 4 on the list of storm-related fatalities, behind flooding, at 84; tornadoes, 57; and lightning, 49.

  • Bitterly cold weather has annually resulted in 24 fatalities, on average, in the United States.

  • About 70 percent of the people who are killed or injured due to winter storms are in automobiles. About 25 percent of the people who are killed or injured in winter storms are caught out in the storm with no place to take shelter.

  • Many deaths and injuries are indirectly related to winter weather occurrences that are not classified as winter storms. These include:

  1. Traffic accidents on hazardous roads

  2. Heart attacks from shoveling snow or other outdoor activities

  3. Hypothermia from prolonged exposure to cold

  4. Frostbite

  5. Avalanches

Illinois winter weather facts

  • Since 1998, 88 percent of all winter weather storms -- those with heavy snow and significant icing -- in central and southeast Illinois have had advance warning by the National Weather Service in Lincoln, with an average lead time of 16.3 hours.

  • There has not been a winter in Illinois without a severe winter storm in the past century.

  • Illinois experiences five severe winter storms each year, on average.

Interesting winter weather facts

  • In the Midwestern United States, Marquette, Mich., is the snowiest city, with an average annual snow accumulation of nearly 130 inches! In central Illinois, the town of Minonk, in northeast Woodford County, has the highest average annual snowfall, with 27.1 inches.

  • The biggest snowstorm to affect central Illinois occurred Dec. 18-20, 1973, when 14 to 22 inches of snow was measured along and just south of Interstate 72. The highest total was in Paris, in Edgar County, which had 21.5 inches of snow.

  • In the Midwest, it usually takes about 13 inches of snow to yield 1 inch of water. This ratio can change from storm to storm. "Dry" snow that is accompanied by very cold temperatures may take as much as 25 inches of snow to yield an inch of water, while "wet" snow from weather systems that originate near the Gulf of Mexico can produce 4 inches of snow for every inch of water.

  • The coldest temperature to be recorded in the state occurred in the central Illinois town of Congerville, in Woodford County, when the mercury dipped to 36 below zero on Jan. 5, 1999.

  • The coldest temperature ever recorded in the continental U.S. was 70 below in Rogers Pass, Mont. Alaska's coldest reading was 80 below at Prospect Creek. The world-record coldest temperature was 129 below at the South Pole.

Economic impacts of weather forecasts and warnings

  • 33 percent of the U.S. gross national product is affected by National Weather Service forecasts.

  • Economists have estimated that improved El Nino forecasts have resulted in annual savings of nearly $300 million for U.S. agriculture by altering planting decisions.

  • A 1-degree improvement in temperature forecasts could decrease the annual cost of electricity by at least $1 billion.
