The National Weather Service in Dallas has completed its preliminary assessment of a tornado outbreak in Texas. Six tornadoes were confirmed by the survey teams. You can see the location and tracks of these tornadoes in the graphic to the left.
Four of the twisters were rated EF-0, the weakest rating on the Enhanced Fujita Scale. One tornado was rated an EF-1, and the tornado that struck parts of Dallas was ranked an EF-2, with estimated winds of 115mph. This represents the strongest tornado to hit Dallas since an F2 hit portions of the town in April 1974.
The winds in the Dallas tornado were strong enough to collapse a part of an industrial roof and take down a load bearing wall. Fortunately no injuries were reported with this tornado.
This small outbreak of tornadoes was produced by the remnants of Tropical Storm Hermine. It serves as a reminder that although the peak tornado season is well behind us, there remains a threat for tornadoes at any time of the year if the conditions are right. Many here in Iowa recall the killer tornado that struck Woodward Iowa on November 12th, 2005.
