Hurricane Amanda underwent explosive development after it formed well off the Mexican coast, soon reaching Category-4 force.
With maximum sustained winds of 155 mph on May 25, Amanda became the most powerful May Pacific storm on record.
That beat out Hurricane Adolph of 2001, which generated winds of 145 mph on May 29 of that year.
Amanda was predicted to spin out over open waters of the Pacific without threatening any land areas.
