Tracking the Facts on Tornado Safety

POSTED: 11:56 AM Mar 12 2013

WHAT CAUSES TORNADOES

Tornadoes are strong and violent rotating columns of air which extend from a thunderstorm to the ground. Tornadoes develop when warm, moist air rises and contacts a cold jet stream. Before the storms actually develop, change in wind direction and speed with increasing height creates a spinning effect. Within the thunderstorm, air then rises and tilts the rotating air to a vertical position and this forms a tornado.

WHEN ARE TORNADOES MOST LIKELY TO OCCUR?

Tornadoes are not restricted to any specific region or time, but most often occur in early Spring and develop in the Central Plains. In Texas, tornadoes occur most frequently in April, May, and June between 3:00 p.m. and 6:00 p.m. Typically a tornado will travel along the ground at 35 miles per hour for less than 15 miles. These storms are, however, the most destructive atmospheric phenomena. Clues that a tornado may be coming are dark, greenish skies, wall clouds, large hail, and a loud roar (similar to a freight train).
