Hurricane Alex made its final landfall at 9pm, Wednesday June 30th, along the northern Mexican coast around 110 miles south of Brownsville as a Category 2 storm with maximum sustained winds of 105 mph. Alex was the first Hurricane in June for the Altantic Basin since 1995, and the strongest in the month of June since Hurricane Alma in 1966. Alex was a very large hurricane with tropical storm force winds extending over 200 miles from the center. Although Alex passed over 200 miles south of Corpus Christi, tropical storm force wind gusts were measured as far north as Port O'Connor, George West, and Cotulla. The strongest winds were observed on the barrier island from Port Aransas to Baffin Bay where peak wind gusts exceeded 60 mph.||Overall, the impacts to the Middle Texas coast were minimal. Storm tides peaked just below 4 feet mean sea level at tide stations along the coast producing flooding along area beaches. About a half dozen tornadoes occurred within the outer rain bands from Alex. These tornadoes caused mostly minor tree damage. Radar indicated the possibility of several more tornadoes, however NWS survey teams were unable to locate any additional damage. Heavy rainfall and flooding proved to be the biggest impact. Rainfall totals of 3 to 6 inches with isolated amounts near 10 inches were observed across South Texas. This resulted in flooding of many roads and farm fields from Alice to Sinton.||Less than $10 thousand in damages occurred from the 6 tornadoes. However, nearly $5.5 million in damages resulted from flooding associated with the heavy rainfall, of which $5.25 million was observed in Webb County from flooding along the Rio Grande. Nearly $1 million in crop damage, mostly to grain and sorghum was observed. In addition, flooding resulted in two fatalities.

Tornado reported on ground over open country 9 miles NW of Kingsville by a spotter. Location is an estimate. This tornado occurred in the outer rainbands of Hurricane Alex.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:55 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
