Tree and Fence Damage the result of an EF-0 tornado

May 19, 2021

The National Weather Service Office (NWS) in Forth Worth has determined that Sunday's tree and fence damage in Williams, Goar and Caruth Parks was the result of an EF-0 tornado with a maximum wind speed of 75 miles per hour.

Thankfully, the very short-lived tornado did not damage any homes or result in injuries. The NWS says a second tornado formed minutes later with winds up to 90 miles per hour near Northhaven Road, west of U.S. 75. Classified as an EF-1 tornado, that activity prompted a Tornado Warning for Northern Dallas County.

Captured by a park security camera, here is what the storm looked like as it came across Williams Park just seconds after 2 p.m.

Other details about the EF 0 tornado:

Path Length:  0.27 miles
Width:  30 yards

This EF 0 tornado, with maximum winds of 75 miles-an-hour traveled 475 yards with a duration of approximately 30 to 45 seconds.  Moments after the storm passed through Goar Park, wind conditions at City Hall registered 6 miles-an-hour. 

On Tuesday, May 18, after the EF 0 determined had been made, the NWS office in Fort Worth reported that a precautionay Tornado Watch had not been issued for the area prior to the tornado because observed atmospheric conditions in North Texas were not favorable for the formation of tornadoes.

Storm Siren Activation

At 2:08 p.m., eight minutes after University Park’s EF 0 tornado, the NWS issued a Tornado Warning for locations primarily north of Northwest Highway.  That Warning included a small section of University Park.  However, since potential tornadic activity was already out of University Park and headed north, storm sirens in University Park, including the siren on the SMU campus were not activated.  Because dangerous conditions were now present in portions of North Dallas, Richardson and Addison, storm sirens were activated for those locations.  An EF 1 tornado, with maximum winds of 90 miles-an-hour touched down briefly on North Haven Road at 2:12 p.m.  That tornado heavily damaged a home and did substantial damage to a business across the street.

CodeRed Watches and Warnings

CodeRed Watches and Warnings are directly tied to the issuance of Watches and Warnings generated by the NWS. Because the NWS did not issue a Warning for the EF 0 tornado, subscribers were not notified. Immediately after the NWS issued a Tornado Warning for portions of North Dallas, Richardson and Addison, about 250 University Park addressed included in the Warning area did receive a call because, as the polygon drawn below shows, they fell within the NWS warned area.
