I can never remember the difference between a tornado warning and a tornado watch. Which one is worse and when should I seek shelter?
This is an excellent question!
A tornado watch means that conditions are favorable for severe thunderstorms that are capable of producing tornadoes. This does not mean any tornadoes have been sighted yet and can cover large areas, even multiple states at a time. You can go about life as you normally do, just being more aware of the weather. This would be an excellent time to get your emergency supplies, such as candles, flashlights, radios, etc. nearby so that you have them in case it turns from a watch to a warning.
A tornado warning means that a tornado is occurring or imminent and you should seek shelter as soon as possible. Warnings usually cover only one or two counties at a time.
There is a third option that is rarely used called a tornado emergency. A tornado emergency is like an upgraded tornado warning. When you hear tornado emergency, you should expect a violent tornado that will cause severe destruction.
An easy way to remember is that during a tornado watch, they are just watching for the possibility of a tornado, but during a tornado warning, they are warning you that one may be headed towards you and to seek shelter immediately, preferably in your Tornado Alley Armor Storm Shelter. =)
