NWS Storm Survey: EF-3 damage in Murfreesboro, TN tornado - April 10, 2009

The NWS has conducted an initial aerial and ground survey and will be back on the ground Easter Sunday conducting additional surveys. Preliminary indications are that the Murfreesboro Good Friday tornado was at least an EF-3 with 150 mph winds, a path length of 15 miles over 22 minutes, and it was up to 1/2 mile wide at one point near I-24. There were also indications on amateur video and on the ground that the tornado could have had multiple vortices. The NWS survey results, including photos, can be found here.

12-15 homes were destroyed, dozens more had significant damage, the upper level of a 2-story office complex was removed, tractor trailers were laid on their sides, some homes were moved off their foundation, and trees were de-barked. The NWS indicates it is possible that the damage was greater than EF-3 once their survey is complete.
