I am pleased to announce that 2009 tornado data has been added to the database. 1,156 tornadoes were added this year, bringing the total number of tornadoes in the database to 53,253. Just visit the front page to get started.
Note that, at the time of writing, the SPC has not assigned sequential national or state tornado numbers. However, they are using temporary non-sequential tornado numbers for the national number, which has been carried over here. Once the SPC officially sequences the tornadoes, our data will be updated.
