Tornados are one of nature’s most violent storms. Spawned from powerful thunderstorms, tornadoes can uproot trees and buildings and turn harmless objects into deadly missiles. They can devastate a neighborhood in seconds. Tornadoes appear as rotating, funnel shaped clouds that extend to the ground with swirling winds that can reach 300 miles per hour. Damage paths can be in excess of one mile wide and 50 miles long. Every state is at some risk from tornado hazards.
A tornado is possible. Remain alert for approaching storms. Watch the sky and stay tuned to weather radio, commercial radio, or television for information.
