The peak of severe storm season is from April to July, but severe storms can hit at anytime during the year. These tornadoes have wind gusts from 73-112 mph and can peel surfaces off roofs, overturn or move mobile homes off foundations, push moving automobiles off the road and destroy attached garages. Fifteen tornadoes have hit Delaware County since 1953, two of which were F4 in scale. They are capable of leveling well-constructed houses, blowing structures off weak foundations, throwing cars and turning other objects into large missiles. Indiana is ranked third in the country for deaths per 10,000 miles, third in annual tornadoes per 10,000 square miles, and eighth in number of killer tornadoes.
Tornadoes never strike big cities.
Opening windows to equalize air pressure will save a roof, or even a home, from destruction by a tornado. Highway overpasses are a safe place to seek shelter for those people who are on the road when they see a tornado coming.
