Florida recorded the highest concentration of tornadoes in the United States between 1950 and 2010, according to a Weather Channel expert.

Greg Forbes calculated a Top 10 list by counting the number of tornadoes between 10,000 square miles in each state.

Here is what he had to say about what makes Florida such a tornado magnet:

"Several things contribute to there being a lot of tornadoes in Florida. ... It's surrounded by water so they can get tornadoes any month. Also, Florida is the thunderstorm capital of the United States. It has the most thunderstorms per square mile and some of those storms produce tornadoes.

"Florida is also a frequent target for hurricanes. Hurricanes often spawn tornadoes once they move inland. So the combination of spring tornado season and summer and fall hurricane season creates an almost year-round tornado threat for Florida."

States rounding out the list, in order, from second to 10th are: Kansas; Maryland; Illinois; Mississippi; Iowa; Oklahoma; South Carolina; Alabama; and Louisiana.
