A tornado emergency is a stronger wording of tornado warnings used by the National Weather Service in the United States. It is used when a large, powerful tornado is in an area with a lot of people. It means that a very large amount of damage and a high possibility of a lot of deaths are expected.
The term was first used on May 3, 1999 when an F5 tornado hit just south of Oklahoma City in Moore. Between 5:30 and 6:00 PM, a large, powerful tornado was heading for Oklahoma City, leading to the first tornado emergency.
