The 2011 Pacific hurricane season consisted of the events that occurred in the annual cycle of tropical cyclone formation over the Pacific Ocean north of the equator and east of the International Date Line. The official bounds of each Pacific hurricane season are dates that conventionally delineate the period each year during which tropical cyclones tend to form in the basin according to the National Hurricane Center (NHC), beginning on May 15 in the Eastern Pacific proper (east of 140°W) and June 1 in the Central Pacific (140°W to the International Date Line), and ending on November 30 in both areas. However, tropical cyclogenesis is possible at any time of year. [1] The season generated eleven  tropical storms, which is below the 1991–2020 average of fifteen. [1] However, all but one became hurricanes and six further strengthened into major hurricanes, [nb 1] eclipsing the 1991–2020 averages of eight hurricanes and four major hurricanes. [1] There were also two tropical depressions that remained below tropical storm status. The first system, Hurricane Adrian, formed on June 7; the final, Hurricane Kenneth, was the latest in a calendar year to exist east of 140°W since 1983, dissipating on November 25. [2]

Several tropical cyclones impacted land during the 2011 season. The deadliest was Tropical Depression Twelve-E, which was part of a large area of torrential rains over Central America in mid-October. Widespread and destructive flooding and mudslides occurred in southeastern Mexico and Guatemala; at least thirty-six fatalities were directly attributed to the tropical depression itself, with many more in Central America being blamed on the overall weather system. [nb 2] On the same day that Twelve-E made landfall, Hurricane Jova came ashore further to the west, in the Mexican state of Jalisco, at Category 2 strength; high winds and heavy rains killed nine people [7] and caused at least MX$3.164 billion (US$254.3 million) in losses. [nb 3] Hurricane Beatriz in June claimed four lives when it passed a short distance off the Mexican state of Colima, producing strong winds and locally significant flooding on land. [10] Hurricanes Adrian in early June, Dora in July, and Hilary in late September all threatened or brushed the Pacific coast of Mexico but only caused minor peripheral effects. [11] [12] [13]

Prior to 2015, two time zones were utilized in the Eastern Pacific basin: Pacific east of 140°W, and Hawaii−Aleutian from 140°W to the International Date Line. [14] [15] For convenience, each event is listed in Coordinated Universal Time (UTC) first, using the 24-hour clock (where 00:00 = midnight UTC), [16] with the respective local time included in parentheses. Figures for maximum sustained winds and position estimates are rounded to the nearest five units (knots, miles, or kilometers) and averaged over one minute, following National Hurricane Center practice. Direct wind observations are rounded to the nearest whole number. Atmospheric pressures are listed to the nearest millibar and nearest hundredth of an inch of mercury. This timeline documents the formation of tropical cyclones as well as the strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season. It also includes information that was not released while the storm was active, meaning that data from post-storm reviews by the National Hurricane Center and the Central Pacific Hurricane Center is included.

Notes

  1. ↑ A major hurricane is a Pacific or Atlantic hurricane that reaches Category 3 or higher on the five-level Saffir–Simpson scale, with maximum sustained winds of at least 111 mph (179 km/h). [1]
  2. ↑ Cited to multiple sources: [3] [4] [5] [6]
  3. ↑ The estimate of monetary losses due to Hurricane Jova was ascertained by combining figures provided by La Jornada  –MX$885 million (US$71.1 million) in Jalisco; [8] and CENAPRED  –MX$2.279 billion (US$183.2 million) in Colima. [9]
  4. ↑ On November 6, daylight saving time ended in most areas of the basin, which resulted in the gap between UTC and local time widening by one hour. Hawaii was not affected; the state has not observed daylight saving time since 1945. [23] [24]
