An upper level disturbance moved over the area, and a lingering frontal boundary was across the Permian Basin.  Upper level lift associated with an area of intense winds aloft moved over the region.  There was good wind shear, moisture, and instability across West Texas and southeast New Mexico.  Two other boundaries were moving toward the area and possibly collided with the initial boundary.  These conditions combined to create good lift in the atmosphere which resulted in widespread thunderstorms with large hail across southeast New Mexico and the Permian Basin.  The wind shear created spin in the atmosphere which allowed for tornadoes to develop in the Permian Basin and southeast New Mexico.  Deep moisture across the area resulted in flash flooding that developed in the Permian Basin.

Location: NOTREES
Tornado F-scale: EF1
Property damage: 30.00K
Reported by: Trained Spotter

A supercell thunderstorm developed over Andrews County during the evening hours of September 17th.  This storm encountered a stationary boundary and began moving southeast.  The storm began to form a hook echo at 6:30 pm CDT as it moved toward Highway 115 in southwest Andrews County.  Eyewitness reports from storm chasers and spotters in the area indicate that the initial tornado began at 7:13 pm CDT near the intersection of Andrews, Winkler and Ector Counties.  Videos taken of the tornado show it touching down and lifting several times before eventually staying on the ground for several minutes over far northwest portions of Ector County.  The tornado moved south southeastward across open fields of rural Ector County just west of FM 181.  The damage assessment team looked at several different indicators to determine tornado intensity.  The tornado snapped several electrical power poles and overturned a tank battery along its path.  These damage indicators suggest EF1 intensity with wind speeds estimated at 90 to 105 mph.  Near the end of the life cycle of the EF1 tornado, a weak anticyclonic circulation developed on the forward flank of the supercell around 7:25 pm CDT.  This circulation moved southwest to the west of FM 181 and dissipated around 7:35 pm CDT. Storm chasers and spotters identified this funnel looking north from Goldsmith around 7:30 pm CDT.  There was no evidence of damage or reports of the funnel cloud touching down.  The tornado path width was estimated and the cost of damage is a very rough estimate.
