Hurricane Blas was a Category 1 hurricane that brought winds and flooding to several Mexican states in June 2022. The second named storm and second hurricane of the 2022 Pacific hurricane season, Blas developed from a low-pressure area off the coast of southwestern Mexico. It became a tropical depression on June 14. and strengthened into a tropical storm later that same day. Blas became a hurricane the next day, while paralleling the coast. The system reached its peak intensity on June 17, at 15:00 UTC, with maximum sustained winds of 80 knots and a central pressure of 976 mbar (28.82 inHg). Later, Blas turned to the west and weakened, becoming a tropical depression on June 20, before transitioning into a post-tropical cyclone on that same day.

The 2022 Pacific hurricane season was an above average hurricane season in the eastern North Pacific basin, with nineteen named storms, ten hurricanes, and four major hurricanes. Two of the storms crossed into the basin from the Atlantic. In the central North Pacific basin, no tropical cyclones formed. The season officially began on May 15 in the eastern Pacific, and on June 1 in the central; both ended on November 30. These dates historically describe the period each year when most tropical cyclogenesis occurs in these regions of the Pacific and are adopted by convention.
