What to look for:
Although tornadoes occur in many parts of the world, these destructive forces of nature are found most frequently in the United States east of the Rocky Mountains during the spring and summer months. In an average year, 800 tornadoes are reported nationwide, resulting in 80 deaths and over 1,500 injuries. A tornado is defined as a violently rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of 250 miles per hour or more. Damage paths can be in excess of one mile wide and 50 miles long.
Tornadoes can occur at anytime of day, at anytime of the year. The average tornado moves from the wouthwest to the northeast, but tornadoes have been known to move in any direction. The average forward speed is 30 MPH, but may vary from nearly stationary to 70 MPH.
Tornadoes are classified by the severity of damage that they cause. This is rated on a scale of 1 to 5 known as the FUJITA SCALE. Tornadoes that are rated as an F-3 or higher are said to be Violent Tornadoes. The earlier mentioned Bullitt County tornado was mainly an F-3, but did reach F-4 status briefly.
