State-By-State Tornado Count for USA through June, 2013 via @NWSSPC

Here’s a very interesting map from the Storm Prediction Center of the state-by-state tornado count as of the end of June 2013. In spite of some brief active periods, especially the May mayhem in Oklahoma, this year has been below normal in the numbers of tornadoes. Currently, Oklahoma and Texas have the number one and two rankings respectively. It’s interesting to note that some states, such as Alabama, are currently at half the climatological normal number of tornadoes. Perhaps the most important factor a map like this can convey to us is that tornado occurrence across the USA varies a great deal from year to year. The long-term “big picture” climatology is ultimately the most important data to take into account when considering the true tornado risk.
