No hurricanes struck the Texas coast in either 1990 or 1992. The largest 

 storms in the Gulf of Mexico those two years were: Hurricane Diana, a 

 minimal storm, which crossed Yucatan and struck the Mexican mainland on 

 August 8, 1990; Tropical Storm Marco, which skirted the west coast of Florida 

 and made landfall on October 12, 1990; and Hurricane Andrew, a major storm, 

 which struck the Louisiana coast (about 500 km east-northeast of Colorado 

 River, TX) on August 26, 1992. The wave data show long-period (14-1- sec)
