December Tornado Information

 After our recent episode of severe weather on Monday, December 10, 2012 we’ve had several questions and comments on the frequency of tornadoes in December. As you can see by the above graph, December has the lowest frequency of tornadoes of any month for our forecast area of southeast Louisiana and south Mississippi. However, the historical record shows that tornadoes can and do occur in our region during December. Since December 2006, five of the last seven years at least one tornado occurred in our forecast area during the month of December. Fortunately, most tornadoes are weak (EF0 or EF1). Interestingly, and a note of caution, one of the strongest tornadoes recorded in Southeast Louisiana occurred at approximately 105AM, December 6, 1983 when an F4 rated violent tornado struck a subdivision near LaPlace, injuring at least 25 people and destroying or severely damaging at least 30 houses.

Note on graph above: The graph is based on parish/county tornado count, therefore a few longer track tornadoes crossing several parishes results in a slight over-count of total tornadoes. is the U.S. government's official web portal to all federal, state and local government web resources and services.
