context_page_description: The 1990 Pacific hurricane season saw a then-record 16 hurricanes form. Throughout the year, 21 tropical cyclones became named storms in the eastern Pacific Ocean. Hurricane Alma formed on May 12, 1990, three days before the season's official start on May 15. The Central Pacific hurricane season began on June 1, covering tropical cyclone formation in the region between 140°W and International Dateline. Hurricane Trudy was the last storm to dissipate, doing so on November 1, nearly a month before the Pacific hurricane season officially ended on November 30.
  The season produced twenty-seven tropical depressions, of which twenty-one became named storms, and sixteen strengthened into hurricanes. Six out of the sixteen hurricanes strengthened into major hurricanes. Despite high levels of activity, Rachel was the only system to make landfall, bringing floods to Northwestern Mexico and the Southwestern United States. Thousands were left homeless, and there were 18 confirmed fatalities. Additionally, the remnants of Hurricane Boris brought light showers to California.
