Tornadoes - March 2013
NCDC transitioned to the nClimDiv dataset on Thursday, March 13, 2014. This was coincident with the release of the February 2014 monthly monitoring report. For details on this transition, please visit our public FTP site and our U.S. Climate Divisional Database site.
According to data from the Storm Prediction Center, during March, there were 18 preliminary tornado reports. This is well below the 1991-2010 average of 80 for the month, and marks one of the ten slowest Marches on record in terms of reported tornadoes. The last March with less than 20 tornadoes occurred in 1978, when 17 tornadoes were confirmed. March marks the beginning of the more active time of year, with tornado activity typically peaking in May and June. The most active tornado day during March was the 18th when a storm system moved through the Southeast, spawning 10 weak tornadoes in Tennessee, Alabama, and Georgia, causing only minor damage. The above-average tornado activity in January and February, combined with the slow March, led to a near-average preliminary tornado count of 138 for the year-to-date period.
