Imagine tuning in your favorite program and suddenly hearing this on TV:
“The National Weather Service has issued a tornado warning. Seek shelter immediately in a small closet or bathroom near the center of your house on the lowest floor. Storm spotters have sighted a tornado in progress on the southwest edge of town moving northeast at 20 miles per hour. Take shelter now!”
No doubt, you would do exactly as you were told, because tornado warnings are to be obeyed.
The National Weather Service issues both tornado watches and tornado warnings. A tornado watch means that in the watch area the possibility exists for storms that could contain tornadoes. A tornado warning means a tornado has been detected by radar or sighted. Here’s how the National Weather Service knows where and when tornadoes are forming.
