Rare tornado emergencies issued in Mississippi on Wednesday. How rare are they?
The National Weather Service issued two tornado emergency alerts in Mississippi on Wednesday night, marking the third and fourth of the year. Tornado warnings and watches are more common, but emergencies represent a rare third category, signifying the most severe type of tornado alert. A tornado emergency is issued when a violent tornado has touched down in the watch area, and there is a threat to human life and property, according to the National Weather Service. There have been 318 tornado emergencies issued since May 1999, according to data from the Iowa Environmental Mesonet. The Iowa Environmental Mesonet collects and archives information related to weather from a variety of sources. Tornado warnings have the highest frequency of the three types of alerts issued. Since 2005, an average of 2,800 tornado warnings have been issued annually in the United States. For emergencies, it’s about an average of 13 annually. Before Wednesday, two tornado emergencies had occurred in the U.S. this year – one in Oklahoma and one that was issued in March for Knox, Indiana.
