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 Scattered showers and thunderstorms initially began to produce rainfall around midday on the 1st. This activity gradually evolved toward heavy tropical downpours, especially during the evening hours of the 3rd through the morning hours of the 4th.

The Texas Tech University West Texas Mesonet sites near Ralls and White River Lake recorded storm total rainfall amounts of 6.74 inches and 6.10 inches respectively.

Four-day storm total rainfall amounts measured by the Crosbyton National Weather Service cooperative observer shattered records for Crosbyton per reports from the Crosby County Reporter-Examiner. The official observer measured 9.43 inches, which exceeded the local record for total July rainfall of 8.40 inches set in 1900.

Local agricultural officials reported that the rains resulted in no adverse impacts for Crosby County crops. As a result of the heavy rain and subsequent run-off, however, White River Lake experienced a rise of nine feet which crested on the 12th.
