While Alice left almost unprecedented flooding in its wake , the storm itself was not an unheard-of occurrence : a similar storm in 1921 , which followed a comparative track , caused significant flooding in Texas as well , albeit not in the same areas affected by the floods of 1954 . Following the devastation left by Alice , members of the U.S. Air Force , Navy , and Army flew 21 helicopters with over 81 tons of relief supplies to the affected people of Mexico and Texas , including food , water , medicine , and clothing . The disastrous flooding caused by Hurricane Alice along the Rio Grande accelerated the joint US – Mexico Amistad Dam project , a series of flood control dams designed to prevent similar catastrophes in the future . The project , in the planning stages for decades before the storm , was finally begun in 1960
