Timeline of the 2011 Pacific hurricane season
2011 Atlantic hurricane season
2011 Pacific typhoon season
2011 North Indian Ocean cyclone season
The 2011 Pacific hurricane season was a below average season in terms of named storms, although it had an above average number of hurricanes and major hurricanes. During the season, 13 tropical depressions formed along with 11 tropical storms, 10 hurricanes and 6 major hurricanes. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. The season's first cyclone, Hurricane Adrian formed on June 7, and the last, Hurricane Kenneth, dissipated on November 25.
Despite the decrease in storms, there were several intense and destructive hurricanes this season. Hurricane Beatriz killed four people in Southwestern Mexico. Hurricane Jova killed eight and caused $203.67 million (2011 USD) in damage to Western Mexico. Tropical Depression Twelve-E killed 30 people in Central America. Meanwhile, Kenneth became the strongest November storm at the time. Hurricane Hilary brought additional flooding to Southwestern Mexico.

In advance of each Pacific hurricane season, forecasts of hurricane activity are issued by the United States National Oceanic and Atmospheric Administration (NOAA)'s Climate Prediction Center and Mexico's Servicio Meteorológico Nacional (SMN). These include weekly and monthly changes in significant factors that help determine the number of tropical storms, hurricanes, and major hurricanes within a particular year. According to NOAA, the average eastern Pacific hurricane season between 1981 and 2010 contained roughly 14 tropical storms, 7 hurricanes, 3 major hurricanes, with a near-normal accumulated cyclone energy (ACE) index of 113.Climate Prediction Center http://www.cpc.ncep.noaa.gov/products/outlooks/background_information.shtml https://web.archive.org/web/20100603105643/http://www.cpc.noaa.gov/products/outlooks/background_information.shtml Background Information: The North Atlantic Hurricane Season National Oceanic and Atmospheric Administration August 6, 2015 June 3, 2010 January 19, 2017 Broadly speaking, ACE is a measure of the power of a tropical or subtropical storm multiplied by the length of time it existed. It is only calculated for full advisories on specific tropical and subtropical systems reaching or exceeding wind speeds of 39 mph. NOAA typically categorizes a season as above-average, average, or below-average based on the cumulative ACE index, but the number of tropical storms, hurricanes, and major hurricanes within a hurricane season is sometimes also considered.
On May 19, the Climate Prediction Center released its pre-season outlook. The scientists stated a 70% chance of a below-normal season, a 25% chance of a near-normal season and a 5% chance of an above-normal season. The climatologists expected 9–15 named storms, with 5–8 becoming hurricanes, and 1–3 becoming major hurricanes. The accumulated cyclone energy was expected to be 45 to 105% of the median. The below-normal activity forecast was because of increased wind shear and a high expectation of El Niño–Southern Oscillation (ENSO)-neutral conditions (no El Niño or La Niña) throughout the peak months of July, August and September, together with lingering La Niña conditions at the beginning of the season.NOAA: 2011 Eastern Pacific Hurricane Season Outlook http://www.cpc.ncep.noaa.gov/products/Epac_hurr/Epac_hurricane.html Climate Prediction Center June 9, 2011 https://web.archive.org/web/20110606065117/http://www.cpc.ncep.noaa.gov/products/Epac_hurr/Epac_hurricane.html June 6, 2011 live
Seasonal summary
270px|thumb|right|In the eastern Pacific, two simultaneous systems on October 11: Tropical Storm Irwin (left) and Hurricane Jova (right)
The season got off to an active start with first storm, Adrian, becoming one of only a handful of tropical cyclones to attain Category 4 status in June. Four other storms, Dora, Eugene, Hilary, and Kenneth attained Category 4 status. Dora was the strongest storm of the year, peaking at 155 mph, just short of Category 5 status. The month of August was about average in terms of the number of storms, with the strongest of the month being Eugene. However, the first half of September had very little activity, due to the return of a La Niña event. Tropical Depression Eight-E was the only storm in the first half of September, when it dissipated on September 1.
Hilary became the second storm to form in September, becoming the fourth major hurricane of the season, during the afternoon hours of September 22. After Hilary, Jova unexpectedly became the fifth major hurricane of the season during the early morning hours of October 10. Tropical Depression Twelve-E killed 30 people in Central America when it made landfall near El Salvador on October 12. On November 19, Kenneth formed as a tropical depression and quickly strengthened into a hurricane two days later. Kenneth became the first major hurricane in November and latest-forming major hurricane in the eastern north Pacific basin in the satellite era, until being surpassed by Hurricane Sandra in 2015; the last to do so was Winnie in 1983, which only peaked at Category 1 hurricane status. Hurricane Kenneth, however, intensified to attain Category 4 status on November 22, which broke the record at the time.
The accumulated cyclone energy (ACE) index for the 2011 Pacific hurricane season as calculated by Colorado State University using data from the National Hurricane Center was 120.9 units.The total represents the sum of the squares of the maximum sustained wind speed (knots) for every (sub)tropical storm's intensity of over 33 kn mph km/h, divided by 10,000 while they are above that threshold; therefore, tropical depressions are not included.

Hurricane Eugene
EPac Eugene 2011-08-03 2110Z.jpg Eugene 2011 path.png July 31 August 6 120 942
On early July 31, a tropical wave developed into a tropical depression in the eastern Pacific a few hundred miles south of Mexico. Meteorologists numbered it "Five-E". It was upgraded to Tropical Storm Eugene only 6 hours after becoming a tropical depression. On the afternoon of August 1, Eugene strengthened into a Category 1 hurricane on the Saffir–Simpson hurricane scale. The next day Eugene further strengthened into a Category 2 hurricane. Early on August 3 Eugene further strengthened into a Category 3 hurricane, making it the third major hurricane of the season. Eugene was expected to weaken after becoming a Category 3. However, on the afternoon of August 3, Eugene strengthened into a Category 4 hurricane on the Saffir–Simpson hurricane scale with winds up to 140 mph km/h on 5. Eugene only maintained Category 4 status briefly, and only six hours later, the hurricane weakened to a Category 3 with winds up to 125 mph km/h on 5. Eugene quickly weakened on August 5 because of unfavorable conditions, dropping from Category 2 status to tropical storm status in only 18 hours. On August 6, Eugene became a post-tropical low as the center of the storm was void of strong convection.Tropical Storm Eugene Advisory 26 http://www.stormpulse.com/pacific/message/201105/30/26 https://web.archive.org/web/20111006020535/http://www.stormpulse.com/pacific/message/201105/30/26 dead October 6, 2011 August 26, 2011 August 26, 2011 During the next few days, Eugene's remnants continued to move westward slowly, while weakening gradually.

Tropical Storm Fernanda
EPac Fernanda 2011-08-16 2220Z.jpg Fernanda 2011 path.png August 15 August 20 60 992
The tropical wave that spawned Tropical Storm Emily in the Atlantic Ocean crossed Central America into the East Pacific on August 6. Producing disorganized deep convection, a surface circulation became discernible on August 13, and the formation of showers and thunderstorms in curved bands around the circulation signified the formation of Tropical Depression Six-E by 18:00 UTC on August 15, about 1,400 nautical miles east-southeast of Hawai'i. An increase deep convection resulted in the depression strengthening into Tropical Storm Fernanda at 6:00 UTC the next morning. A relaxation in shear allowed Fernanda to become more organized and reach an intensity of 45 knots (50 mph) later that day. Fernanda initially moved west under the influence of a subtropical ridge, but it turned northwest through a weakness in the ridge on August 17 into more favorable conditions and strengthened to a peak intensity of 70 mph winds and a minimum pressure of 992 millibars at 6:00 UTC on August 18. Fernanda was the only named storm this season not to clear hurricane strength.
Shortly after reaching peak intensity, the storm crossed into the Central Pacific basin. Continuing west-northwestward, Fernanda began weakening late on August 18 as dry, stable air was entrained into its circulation and it encountered increasing south-southeasterly shear. Most of Fernanda's deep convection had dissipated by August 20, and it degenerated to a remnant low. The post-tropical low continued westward before dissipating the next day a couple hundred nautical miles south of the Hawaiian Islands.Todd B.

Hurricane Hilary (2011)
A tropical disturbance gained enough organization early on September 21 to be declared as a tropical depression, the ninth of the season. Continuing to organize, the depression strengthened into a tropical storm several hours later. On September 22, the meteorologists declared Hilary as a Category 1 hurricane, becoming the seventh of the season. On September 22, it rapidly strengthened into a small, Category 4 hurricane, featuring a well-defined eye and very deep convection. It later reached a peak intensity of 145 mph km/h on 5 at 0600 UTC September 23 (11 p.m. AST September 22). However, the storm began to enter an area of higher wind shear and cooler ocean temperatures on September 24, and Hilary began to weaken. The hurricane weakened back down to a Category 3 hurricane early on September 25, but was later upgraded briefly to a Category 4 again the following afternoon.Brennan Michael Hurricane Hilary Public Advisory #17 http://www.nhc.noaa.gov/archive/2011/ep09/ep092011.public.017.shtml?

During the late hours of October 4, an area of showers and thunderstorms associated with a broad low-pressure area developed several hundred miles to the south-southwest of Acapulco, Mexico. Moving slowly towards the west, the area of disturbed weather quickly organized. Late on October 5, the National Hurricane Center (NHC) noted that the area had a high chance of developing into a tropical cyclone over the next 48 hours. Just several hours later, the NHC began issuing advisories on Tropical Depression Ten-E, several hundred miles to the south of Manzanillo, Mexico. A more gradual type of development took place after then, and the depression was upgraded into Tropical Storm Jova on the afternoon of October 6. Taking advantage of the favorable environment Jova was embedded within, the storm became a hurricane on October 8, and by October 10, the storm was upgraded to a Category 3 hurricane on the Saffir–Simpson hurricane scale. However, shortly thereafter, the storm began an eyewall replacement cycle and weakened to a lower-end Category 2 hurricane. Several hours after landfall in Mexico, Jova dissipated, very early on October 13.EP102011_Jova

The origins of Hurricane Irwin can be tracked back to an area of showers and thunderstorms associated with a low-pressure area that developed several hundred miles to the south of Mexico. Moving towards the west and west-northwest, the low pressure quickly gained organization, and during the pre-dawn hours of October 6, the National Hurricane Center began issuing advisories on newly formed Tropical Depression Eleven-E. Later on October 6, Tropical Depression Eleven-E strengthened to Tropical Storm Irwin, and it became a hurricane the next day. The next day it weakened to a tropical storm. Unlike most tropical cyclones that form in the eastern Pacific Ocean, Irwin's track was very unusual. The system which originally started moving westward, turned north, then east and again back south, and east until dissipation, on October 17, as a remnant low. Also, between October 11 and 14, Irwin weakened into a tropical depression twice and again re-strengthened back to a tropical storm before finally weakening into a tropical depression on October 15. The depression turned west again and dissipated into a remnant low in the late hours of October 16. But the remnants of Tropical Storm Irwin continued to move westward generally, until it dissipated completely, on October 17.http://www.nhc.noaa.gov/archive/gtwo/epac/201110171140/index.php?basin=epac¤t_issuance=201110171140 NHC Graphical Outlook Archive www.nhc.noaa.gov 8 April 2018

EPac 12-E Oct 12 2011 1715Z.jpg 12E 2011 path.png October 12 October 12 30 1004
A tropical wave, the same that spawned Hurricane Phillipe in the Atlantic, crossed Central America into the East Pacific on October 5, during a significant pulse of the MJO. In this favorable environment, the wave generated a low-pressure area in the ITCZ by 18:00 UTC on October 6. Despite initially being hindered by the development of easterly wind shear, the low produced sustain deep convection late on October 11, and organized sufficiently to become Tropical Depression Twelve-E by 00:00 UTC on October 12. The depression moved northward without strengthening and made landfall at 16:00 UTC that day near Paredón, Mexico. The depression rapidly weakened to a remnant low eight hours later and dissipated completely early the next day.
The depression brought torrential rains that caused severe flooding in southeast Mexico and neighboring Guatemala. Up to 12 in mm of rain fell in Guatemala, though not all of it may be because of Twelve-E. 36 deaths were directly attributed to the depression by the government of Guatemala. Numerous additional fatalities resulted in Central America from the pulse of the MJO that helped spawn the depression.Todd B.

However, Kenneth's intensification was short-lived; immediately it moved into an environment of colder waters and stronger wind shear, and started to rapidly deteriorate. Just 24 hours after the cyclone reached its peak, it dropped below hurricane strength and lost most of its central convection. Afterwards, Kenneth weakened at a slower rate, but by November 25, had weakened to a tropical depression, losing almost all of its convection. Early on November 25, Kenneth weakened to a remnant low, with its circulation void of any strong convection. But for the next 3 days, the remnant of the storm continued moving northwestward rapidly as a convectionless vortex, before dissipating completely early on November 28.http://www.nhc.noaa.gov/archive/gtwo/epac/latest/index.php?basin=epac¤t_issuance=latest NHC Graphical Outlook Archive www.nhc.noaa.gov 8 April 2018
