Episode Narrative A plume of middle and upper tropospheric subtropical moisture streamed northward over west Texas during the first few days of July. Scattered showers and thunderstorms produced locally heavy rainfall each afternoon and evening starting on the 1st and persisting through the 3rd. Although little to no adverse public impacts were observed from the rains through the first three days of the month, the remnants of former Atlantic Hurricane Alex spread northward within the persistent tropical moisture plume and began to impact the west Texas South Plains during the late evening hours of the 3rd.

The remnants of Hurricane Alex brought the onset of widespread tropical rains to the South Plains region, with rainfall rates measured to exceed 4.00 inches per hour in some locations. The heaviest rainfall occurred along several convective bands that spanned southwest to northeast over the southern and central South Plains. Thus the most adverse impacts were experienced over portions of Terry, Lubbock, Lynn, and Garza Counties, where isolated locations received more than one foot of rain through the early morning hours of Independence Day.

The Fourth of July flash floods and floods brought extensive damages and economic loss to the area. Local and state officials estimated these losses to approach $16.5 million. The State of Texas declared several South Plains counties a Disaster Area, and federal assistence was requested. In spite of the dramatic agricultural and property damages, no serious injuries were reported.

Remnant flooding, generally near swollen playa lakes, persisted and resulted in prolonged closures of several roadways and highways until the 10th.
Event Narrative Local law enforcement officials initially reported flash flooding along U.S. Highway 82 between Lorenzo and Ralls, where several cars were reportedly stalled in flowing flood waters and high-water rescues were underway. Portions of that highway remained impassable through at least 02:35 CST. Additional motorists were stranded in flowing flood waters along Texas Highway 207 near Ralls.

Flash flooding in Blanco Canyon resulted in dramatic run-off and swelling of the White River. This run-off and associated river rises caused unusually high water flows at Silver Falls along the Caprock escarpment near U.S. Highway 82 east of Crosbyton, which persisted well into the daylight hours of the 4th.

No injuries were reported.
