Timeline of the 2012 Pacific hurricane season

The 2012 Pacific hurricane season was an above-average year in which seventeen named storms formed.[nb 1] The hurricane season officially began on May 15 with the formation of Tropical Storm Aletta in the East Pacific—defined as the region east of 140°W—and on June 1 in the central Pacific—defined as the region west of 140°W to the International Date Line—and ended on November 30 in both basins. These dates conventionally delimit the period during each year when most tropical cyclones form.[2] The final cyclone of the year, Tropical Storm Rosa, dissipated on November 3.

The season produced seventeen tropical storms; ten became hurricanes, and five further intensified into major hurricanes.[nb 2] 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.[4] 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.[5]

This timeline includes information that was not released in real time, meaning that data from post-storm reviews by the National Hurricane Center, such as a storm that was not operationally warned upon, has been included. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season.
