Definitions for "1990 Pacific hurricane season"
The 1990 Pacific hurricane season officially started on May 15, 1990 in the eastern Pacific, and on June 1, 1990 in the central Pacific, and lasted until November 30, 1990. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. However, it exceeded these bounds slightly as the tropical depression that eventually became Hurricane Alma formed May 12.
