The path drawn at its surveyed width of 1,760 yards (1.00 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

This tornado was a continuation from Van Zandt County. This tornado began nearly as the last tornado dissipated to the south and west. The parent supercell cycled another tornado about a mile to the east and northeast of the previous storm. This tornado quickly grew to a large tornado, becoming slightly less than one mile wide at its widest point. The tornado was at the strongest near Interstate 20 and FM 17 just north of Canton. The survey crews found continuous damage between Canton and Fruitvale, and then additional damage as far north as Emory, and Lake Fork. Several homes, businesses, and farm buildings were damaged or destroyed in the 40 mile continuous damage path. This tornado occurred for over an hour, and spanned most of Van Zandt, and nearly all of Rains Counties during the 80 minute track.

The wider storm

A deep low pressure system near the Four corners continued to move east, causing early morning thunderstorms to develop along the Texas Panhandle and into Oklahoma. A cold front was moving southeast across the state and entered our northwestern

counties around sunrise. The strength of the cap was sufficient to hamper any development until mid afternoon. Deep forcing for ascent approached from from the west while remnant boundaries associated with convection over far East Texas and West Louisiana moved in from the east. By 3:30 PM, several parameters came together for the rapid development of severe storms east of Interstate 35/35E. Pre-frontal convection led to the development of supercells, producing numerous tornadoes over a relatively small area. Additional storm development quickly developed along the cold front with several reports of large hail, and eventually producing a brief EF-0 Quasi-Linear Convective System (QLCS) tornado (Tornado #7).

The survey crew teams determined yesterday that there was a nearly 55 mile damage swath, yet found evidence that there were two tornadoes which caused the damage. One tornado began in western Henderson County and moved into central Van Zandt County. This tornado occluded and dissipated, and a second, long track tornado began nearby. This second tornado was the EF-3 which produced damage on the east side of Canton, Fruitvale, Emory, and finally dissipating near Lake Fork. The first tornado had

a track of approximately 12 miles, while the other had a track of nearly 42 miles.

It is known that four people lost their lives due to these tornadoes, and 59 people were injured.

Began near Dunbar (32.7717, -95.7670).
