7 Tornadoes Touched Down in DFW: NWS

Seagoville tornado was EF1



    The National Weather Service says seven tornadoes touched down in Dallas-Fort Worth Wednesday as the remnants of Tropical Storm Hermine continued their snail's pace push northward through the Metroplex.

    The twister that drew the most attention was the one that touched down west of downtown Dallas just after 6 p.m.  The NWS said that tornado was a low-level EF2 with a swath about a half-mile long and only 100 yards wide.

    Interestingly, even with the short swath, this tornado is the one that appeared to have done the most damage as it ripped through several warehouses inside an industrial park along the 400 block of Mockingbird Lane.

    Along with tearing holes in roofs, the tornado is said to have tossed a big-rig into a warehouse.  The truck was traveling south on Mockingbird when it was picked up, spun around and pushed into the building. Part of the warehouse then came crashing down around the truck. Several passers-by helped the driver escape from the mangled cab before he was transferred to an area hospital.  The driver's injuries were not serious and he was treated and released.

    In Seagoville, an EF1 ripped the roofs from several area homes and apartment buildings. The Seagoville swath is estimated to be 1 mile long and 1/4 mile wide, according to investigators.  

    In all, there were seven tornadoes reported to have touched down during Wednesday's storms that also brought flooding and  record-breaking rain to the Metroplex. The NWS has not issued EF ratings on the remaining five tornadoes.

    With an EF2 tornado, winds range from 110 to 137 mph while with an EF1 the winds range from 86-109 mph. The Enhanced Fujita Scale (EF Scale) is a set of wind estimates, not measurements, based on damage.  (Read more here).
