Tornadoes in the winter and early spring are associated with strong frontal systems that form in Texas and Oklahoma and move eastward toward Caddo-Bossier area. Occasionally, large outbreaks of tornadoes occur with this type of weather pattern. Several states may be affected by numerous severe thunderstorms and tornadoes. Tornado-producing thunderstorms may form as the dryline moves east during the afternoon hours. If other favorable conditions exist, these thunderstorms can produce tornadoes.
Small tornadoes can even accompany tropical storms and hurricanes that move over land.
Tornadoes are most common to the right and ahead of the path of the storm center as it comes onshore. Tornadoes are most likely to occur between 3 and 9 p.m. but have been known to occur at all hours of the day or night. The average tornado moves from southwest to northwest, 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. Remain alert for approaching storms.
