—and ended on November 30 in both regions. These dates conventionally delimit the period during each year when most tropical cyclones form in the northeastern Pacific Ocean. This year, the first storm of the season, Tropical Storm Aletta, formed on May 14, and the last, Tropical Storm Rosa, dissipated on November 3.
The season produced seventeen tropical storms; ten became hurricanes, and five further intensified into major hurricanes. Impact during the season was relatively minimal. In late May, Hurricane Bud paralleled the western Mexico coastline before dissipating, causing minor damage and but no reported fatalities. In mid-June, Hurricane Carlotta came ashore in Oaxaca at Category 2 hurricane intensity, making it the easternmost tropical cyclone in the basin to make landfall at hurricane intensity since 1966. The storm killed seven and caused $12.4 million (2012 USD) in damage.
