A tornado emergency is an unnofficial subcategory of a tornado warning. A tornado warning means that a thunderstorm may soon produce a tornado, or that a tornado or funnel has been spotted or detected.A tornado emergency means that a large and probably very strong tornado has been spotted and is likely capable of causing major damage. The text of a tornado emergency will usually contain the phrase "A large and extremely dangerous tornado..." and then give the tornado's relative location and movement. This warning was created to be more strongly worded than an ordinary tornado warning, which people often do not take seriously.
An F4 or higher tornado (the only higher rating being F5) is classified as violent.
Officially, it is a tornado warning, which means that a tornado has been detected or that the formation of a tornado may be imminent.Unofficially, it is a subcategory of tornado warning called a tornado emergency. A tornado emergency is issued when a large and intense tornado is threatening a populated area.
To be classified as a tornado, a funnel cloud must make contact with the ground. Once the funnel cloud touches the ground, it becomes a tornado and is classified based on its size, intensity, and associated damage.
A tornado watch is given out if general weather conditions favor the formation of tornadoes over the next few hours. A PDS (Particularly Dangerous Situation) tornado watch may be issued if conditions favor the formation of strong to violent tornadoes. A tornado watch usually covers an area at least the size of a state. A tornado warning is issued if a tornado has been spotted or detected or the threat of one is imminent. A tornado emergency is an informal variety of tornado warning meaning that a large tornado is approaching a populated area and is expected to cause major damage. A tornado warning usually covers an area about the size of a county.

The main positive effect of the May 3, 1999 F5 tornado was a new type of unofficial weather advisory: the tornado emergency. A tornado emergency is more urgent than an ordinary tornado warning. It means that a large and potentially very destructive tornado is threatening a populated area. One case of a tornado emergency's effectiveness was on May 4, 2007 when an EF5 tornado destroyed 95% of Greensburg, Kansas. Despite this the death toll was limited to 11. Countless more lives had been saved.
If there is a tornado, call emergency services or 911 for immediate assistance. It's important to seek shelter in a safe location and follow any instructions from local authorities or emergency management. It's also advisable to have a designated emergency contact and plan in place before a tornado occurs.
If there is a tornado emergency, you need to seek shelter immediately. Always seek shelter in a basement or other place low to the ground. Try to stay somewhere where there are no windows.
The Tri-State tornado was most likely an F5.
