Feeder bands from Hurricane Alex began producing tropical storm force wind gusts during the late morning and early afternoon of June 30th in Coastal Kenedy County. Outer feeder bands well ahead of the center of Alex produced sustained winds of 36 mph at Rincon del San Jose Texas Coastal Ocean Observing Network (TCOON) platform shortly after noon, with a peak gust of 47 mph at 5 PM CST (along the Laguna Madre). Stronger winds reached the Baffin Bay TCOON platform (3 to 4 miles north of the Kenedy County shoreline) by late afternoon, with sustained winds reaching 41 mph with a gust to 64 mph a little after 4 PM. Sustained winds were below tropical storm strength over inland Kenedy County, interpolated from the nearby Kingsville Naval Air Station in Kleberg County, just 20 miles north.

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. Although no heavy rains were occurring at the time, wet pavement from earlier heavy rains contributed to the hydroplaning of a vehicle on U.S. Highway 84 near Post around 23:30 CST. The vehicle reportedly came to rest 60 feet off of the highway in a canyon area along the Caprock escarpment. No significant injuries were reported. The Texas Tech University West Texas Mesonet measured storm rainfall totals that included: 9.78 inches at Post, 9.08 inches at Graham, and 5.88 inches at Lake Alan Henry. Local newspapers reported unofficial amounts between 10.00 and 12.00 inches in western Garza County.

Three to five inches of water was reported running over Highway 41, 3 miles east of Delphos. Also 120th road was under approximately 5 inches of water running out of nearby fields.

Ottawa, Kansas · Flood · Jul 4, 18:17 UTC

Law enforcement reported that numerous county roads were closed across the northwest portions of the county. Sandbagging occurred in Colwich and two residents reported two feet of water in the basement. Rainfall amounts ranged from 5 to 7 inches across the area. Street flooding also occurred in Andale, Valley Center and Sedgwick.

A best track is the record a warning agency settles on after the storm, not what it said at the time: position, maximum sustained wind and central pressure every six hours, revised against every observation that came in later. Category is the Saffir-Simpson scale, which runs from Category 1 at 64 kt to Category 5 at 137 kt and reads wind only, so it says nothing about surge or rain. Accumulated cyclone energy adds up the square of the wind through the storm's life, so it counts strength and duration together.
