Tornadoes of 2005
This page documents the tornadoes and tornado outbreaks of 2005, primarily (but not entirely) in the United States. Most tornadoes form in the U.S., although some events may take place internationally, particularly in parts of neigboring southern Canada during the summer season.
Synopsis
The first half of 2005 was fairly slow when it comes to tornadoes. There were no major outbreaks in the first half of 2005, which is rather unusual. The inactivity in what is normally the peak months can be related to a stable low-pressure system that blocked the parade of storms from moving eastward.[1]
The third quarter of 2005 was dominated by the tropics, and many of the tornadoes were related to the many hurricanes and tropical storms of the 2005 Atlantic hurricane season. Several of the tornadoes were destructive.
November was clearly the most active month for tornado activity in the US, with four significant - and completely separate - tornado events, as the wind pattern shifted and the warm tropical Gulf of Mexico added fuel to the fire when cold fronts passed southward, initiating the development of tornado outbreaks. December was much quieter as colder Arctic air became entrenched and the cold fronts became far less active.
