Summary

Alex began as a strong tropical wave in the eastern Caribbean Sea on June 20th, 2010. Alex was officially designated as a Tropical Depression on Friday June 25th as it moved into the central Caribbean. Alex became the first Tropical Storm of the season on June 26th, and strengthened to a strong tropical storm with maximum sustained winds of 65 mph before making landfall in the country of Belize. Alex weakened to a tropical depression as it crossed the Yucatan Peninsula, but quickly regained strength in the warm waters of the Gulf of Mexico. For several days leading up to the final landfall, the National Hurricane Center predicted Alex could strengthen into a Category 2 hurricane and make landfall anywhere from the northeast Mexico coast to the Middle Texas coast.

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.
