What happened
Toward the latter part of August plentiful rains were at last falling over all of the area. This pattern was started by the tropical plume that brought Hurricane Dolly westward through the Bay of Campeche to near Tampico, Mexico, across the Central America to where she dissipated in the eastern North Pacific. Although Dolly was over 1000 miles south of the area, this same plume of deep, tropical moisture locked over Southwest Texas and rained over much of the area on a daily basis through the end of the month.Since a drought is a very loosely defined phenomenon, there is no explicit beginning or end, but for the purposes of Storm Data there is no room for flexibility--only qualifications that can be made in this narrative. The effects in West Texas and Southeastern New Mexico were mainly in the form of crop damage due to the dry weather. Those farms that were able to plant crops late in the season were able to grow crops successfully. With the threat to crops ending in August and the Eastern Pacific cold phase waning, it was felt that a definite trend away from the drought had begun.

Countywide, Glasscock County
$400K damage
What happened
Glasscock County was probably the most affected county in the region by the flooding. Almost the entire county received in excess of 2 inches of rain with the northwest half (about 400 square miles) of the county getting inundated with around 6 inches of rain. Much of this rainfall collected in Mustang Draw that flowed northward into Howard County where the vehicle fatalities occurred. Highway 137 in the northwest part of the county was closed for many days before flood waters receded. The high, swift flows took out fence lines over much of the area.
