This season was much more active than the previous season, although both seasons were below the Pacific typhoon average of 26. The season ran throughout 2011, though most tropical cyclone tend to develop between May and October. The season's first named storm, Aere, developed on May 7 while the season's last named storm, Washi dissipated on December 19. The season was also much deadlier and destructive than the previous season. Typhoon Muifa affected many countries during August. Tropical Storm Talas and Typhoon Roke made landfall over in Japan and were the most destructive since 2009. Typhoon Nesat was the most powerful to strike China since 2008. Tropical Storm Washi, a late but weak cyclone, affected southern Philippines and killed 2546 people. The scope of this article is limited to the Pacific Ocean to the north of the equator between 100th meridian east and the 180th meridian. Within the Northwestern Pacific Ocean, there are two separate agencies who assign names to tropical cyclones which can often result in a cyclone having two names. The Japan Meteorological Agency will name a tropical cyclone should it be judged to have 10-minute sustained wind speeds of at least 65 km/h mph on anywhere in the basin. Whilst the Philippine Atmospheric, Geophysical and Astronomical Services Administration assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N-25°N even if the cyclone has had a name assigned to it by the Japan Meteorological Agency. Tropical depressions that are monitored by the United States' Joint Typhoon Warning Center are given a number with a "W" suffix. __TOC__ Seasonal forecasts TSR forecastsDate Tropicalstorms TotalTyphoons IntenseTCs ACE Ref Average (1965–2010) 26.3 16.4 8.5 295 Extended Range Forecast for Northwest Pacific Typhoon Activity in 2011 http://www.tropicalstormrisk.com/docs/TSRNWPForecastMar2011.pdf March 8, 2011 Saunders, Mark Lea, Adam March 21, 2011 August 6, 2013 Tropical Storm Risk Consortium https://web.archive.org/web/20110321224503/http://www.tropicalstormrisk.com/docs/TSRNWPForecastMar2011.pdf live March 8, 2011 27.8 17.5 7.8 275 May 5, 2011 28.0 17.7 7.6 266 March 8, 2011 Lea, Adam May Forecast Update for Northwest Pacific Typhoon Activity in 2011 http://www.tropicalstormrisk.com/docs/TSRNWPForecastMay2011.pdf August 6, 2013 October 4, 2011 Saunders, Mark https://web.archive.org/web/20111004134053/http://www.tropicalstormrisk.com/docs/TSRNWPForecastMay2011.pdf Tropical Storm Risk Consortium live July 4, 2011 28.3 18.1 8.4 294 July 4, 2011 July Forecast Update for Northwest Pacific Typhoon Activity in 2011 http://www.tropicalstormrisk.com/docs/TSRNWPForecastJul2011.pdf August 6, 2013 live https://web.archive.org/web/20111004134053/http://www.tropicalstormrisk.com/docs/TSRNWPForecastMay2011.pdf October 4, 2011 Tropical Storm Risk Consortium Lea, Adam Saunders, Mark August 5, 2011 28.2 17.9 8.0 281 August 5, 2011 August Forecast Update for Northwest Pacific Typhoon Activity in 2011 http://www.tropicalstormrisk.com/docs/TSRNWPForecastAug2011.pdf August 6, 2013 live https://web.archive.org/web/20111004134242/http://www.tropicalstormrisk.com/docs/TSRNWPForecastAug2011.pdf Lea, Adam October 4, 2011 Tropical Storm Risk Consortium Saunders, Mark Other forecastsDate ForecastCenter Period Systems Ref January 2011 PAGASA January 1 – December 31 20–23 tropical cyclones June 30, 2011 CWB January 1 – December 31 22–26 tropical storms Taiwan Central Weather Bureau http://www.cwb.gov.tw/V7/news/Newsbb/EN/1000628e.doc Three to Five Typhoons Expected to Hit Taiwan in 2011 June 28, 2011 Weather Forecast Center June 28, 2011 .doc September 18, 2018 https://web.archive.org/web/20180918031813/https://www.cwb.gov.tw/V7/news/Newsbb/EN/1000628e.doc dead ForecastCenter Tropicalcyclones Tropicalstorms Typhoons Ref Actual activity: JMA 38 21 8 Actual activity: JTWC 27 18 10 Actual activity: PAGASA 19 14 6 During each season, several national meteorological services and scientific agencies forecast how many tropical cyclones, tropical storms, and typhoons will form during a season and/or how many tropical cyclones will affect a particular country.

On August 4, TSR subsequently slightly revised these predictions within its final update for 2011 to 28.2 tropical storms, 17.9 typhoons, 8.0 "intense" typhoons and an ACE index of about 281. Seasonal summary Timeline of the 2011 Pacific typhoon season During April, two tropical depressions developed but they failed to intensify into tropical storms. Tropical Storm Aere (Bebeng) then developed on May 5, and after causing ₱2.25 billion in damage to Northeastern Luzon and Eastern Visayas, the name Bebeng was retired by PAGASA. The second tropical storm of the season then developed on May 19, and affected the Philippines, Taiwan and Japan before becoming extratropical to the east of Japan. After Tropical Storm Banyan dissipated during October 14, no tropical storms or typhoons were observed within the basin until Tropical Depression 27W developed into Tropical Storm Washi during December 15, due to high vertical windshear and a strong northeast monsoon.Annual Report on the Activities on the RSMC Tokyo - Typhoon Center https://www.jma.go.jp/jma/jma-eng/jma-center/rsmc-hp-pub-eg/AnnualReport/2011/Text/Text2011.pdf Japan Meteorological Agency 2011 Systems Tropical Depression 01W WPac JMA Tropical_Depression_01W_2011-04-01.jpg April 1 April 4 01W 2011 track.png 1004 30 30 On April 1, the JMA reported that a tropical depression had developed within an area of moderate vertical wind shear about 510 km mi 5 on to the southeast of Ho Chi Minh City in Southern Vietnam.Japan Meteorological Agency April 1, 2011 http://www.jma.go.jp/en/g3/ JMA WWJP25 Warning and Summary April 1, 2011 06z https://archive.today/20240522172752/https://www.webcitation.org/5xcadEqAq?url=http://gwydir.demon.co.uk/advisories/WWJP25-RJTD_201104010600.htm May 22, 2024 October 27, 2013 live Joint Typhoon Warning Center United States Navy, United States Air Force April 1, 2011 May 7, 2011 http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/ab/abpwweb.txt May 23, 2024 https://archive.today/20240523155703/https://www.webcitation.org/5xdgjh6qn?url=http://gwydir.demon.co.uk/advisories/ABPW10-PGTW_201104011730.htm Significant Tropical Weather Outlook for the Western and South Pacific Oceans dead Over the next day, the system gradually developed further, before the JTWC initiated advisories on the system and designated it as Tropical Depression 01W.Tropical Depression 01W Warning 1 https://web.archive.org/web/20010430085217/http://weather.noaa.gov/pub/data/raw/wt/wtpn31.pgtw..txt April 30, 2001 October 28, 2013 Joint Typhoon Warning Center United States Navy, United States Air Force April 2, 2011 http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/warnings/ dead However, within hours of this, the depression became devoid of convection as wind shear buffeted the system.

On May 19, the JTWC reported that an area of low pressure had persisted about 510 km mi on to the southeast of Yap. As the system moved towards the northwest under the influence of a subtropical ridge of high pressure, it rapidly consolidated in an area of light to moderate vertical wind shear. The JMA then started to monitor the system as a tropical depression later that day, before the JTWC designated it as Tropical Depression 04W early on May 20. The JTWC then reported later that day that the depression had intensified into a tropical storm with wind speeds of 65 km/h mph on 5, however, it later reported that it had overestimated the wind speeds and consequently lowered the storm's status to a tropical depression, based on observations from Yap island. Late on May 21, both the JMA and the JTWC reported that the depression had now become a tropical storm with the JMA naming it as Songda. Over the next couple of days, the system gradually intensified further while moving northwest into PAGASA's area of responsibility. PAGASA named it as Chedeng. At 12:00 UTC on May 24, the JTWC reported that Songda had intensified into a typhoon. 12 hours later, the JMA followed suit while the system was located about 800 km mi on to the southeast of Manila in the Philippines. It rapidly intensified into a Category 5 typhoon.

As it moved towards the Mindoro Strait the JMA and JTWC began to monitor the system. In the early morning hours of June 9, the Philippines' PAGASA upgraded the system to a tropical depression and reported the storm center to be about 450 km mi on west of Dagupan in the Philippines. The next day, the JMA and JTWC upgraded the tropical depression into a tropical storm, with the JMA naming it Sarika. During the morning of June 11, the JTWC downgraded Sarika to a tropical depression after making landfall in Shantou, China. The JTWC soon issued their final advisory on Sarika. Sarika made landfall on mainland China with winds of 75 km/h mph on 5. As a result of the storm, 23 people were killed in Xianning, and ten more were declared missing.

Both of them started to interact with each other and the other one absorbed the moisture of the other disturbance. On June 15, the JTWC started to monitor an area of disturbed weather within that disturbance that was located about 1350 km mi on, to the southeast of Manila, Philippines. Over the next couple of days the system gradually developed further, before late on June 16, the JMA, JTWC and PAGASA, all reported that the system had developed into a tropical depression, with PAGASA naming it as Egay. Egay continued to develop during June 17, as it moved towards the northeast, and on June 18, the JTWC reported that Egay had intensified into a tropical storm. Fluctuations in intensity occurred over the next several days, before the JMA reported that the system had strengthened into a tropical storm on June 22, naming it Haima. The JTWC also followed suit, by upgrading it to a tropical storm again.Tropical storm Haima hits southern China, forcing ships to stop service http://news.xinhuanet.com/english2010/china/2011-06/22/c_13944284.htm https://web.archive.org/web/20110625032202/http://news.xinhuanet.com/english2010/china/2011-06/22/c_13944284.htm dead June 25, 2011 Lu Hui June 22, 2011 During the evening of June 23, the JTWC downgraded Haima to a tropical depression after making landfall in Zhanjiang, Guangdong, China but upgraded it to a tropical storm again on June 24,.

That evening, the JTWC issued a Tropical Cyclone Formation Alert. Soon afterwards, PAGASA upgraded the system into a tropical depression, naming it as "Falcon". At the time of the upgrade, Falcon was located about 1000 km mi on, east northeast of Cebu City. During the evening of June 21, the JTWC also reported that Falcon had strengthened into a tropical depression. On June 22, both the JTWC and the JMA upgraded Falcon into a tropical storm, and the JMA named it Meari. Meari left the Philippines with 2 deaths and 5 people missing. On the afternoon on June 24, the JMA upgraded Meari to a severe tropical storm as it passed Okinawa, Japan. On June 26, Meari rapidly moved to the Yellow Sea but slowly passed Weihai, Shandong, China, and then the JMA downgraded Meari to a tropical storm on the same day. On June 27, the JTWC downgraded Meari to a tropical depression before it made landfall on North Korea, and the JMA reported that Meari became a low-pressure area later.

It became a tropical disturbance as it passed over the warm waters of the Pacific Ocean. On July 11, both the JMA and JTWC upgraded the tropical disturbance to a tropical depression which was located near Minamitorishima. On July 12, both the JMA and JTWC upgraded the system to a tropical storm and named it Ma-on. Early on July 13, the JMA upgraded Ma-on to a severe tropical storm and later that day strengthened into a typhoon. After absorbing Tokage, Ma-on reached its peak intensity on July 16. The PAGASA named it Ineng on July 17. While Ma-on was affecting Japan, the JTWC downgraded it to a tropical storm in the evening on July 19, before making landfall on Tokushima later in the day. The JMA downgraded Ma-on to a severe tropical storm after it made landfall in Wakayama early on July 20. The JTWC downgraded Ma-on to a tropical depression on July 21, and discontinued advisories the following day. The JMA downgraded Ma-on to a tropical storm early on July 23 and transitioned into an extratropical cyclone east of the Tōhoku region the next day. Tropical Storm Tokage (Hanna) WPac July 13 July 15 Tokage 2011-07-15.jpg Tokage 2011 track.png 35 30 1000 On July 11, the JTWC started to monitor a tropical disturbance that had developed within a poorly organized monsoon trough about 1000 km mi 5 us to the northwest of Hagatna, Guam. Over the next couple of days, the disturbance moved towards the west and despite the system being in an area of low vertical wind shear, deep convection surrounding the system struggled to organize around the disturbances low level circulation center. However, by 06:00 UTC on July 13, it had organized enough for the JMA to declare the disturbance a tropical depression. Over the next two days, the system continued to move towards the west and gradually consolidated further. The JMA then named the system as Tokage, as it had developed into a tropical storm and reached its 10-minute peak wind speeds of 65 km/h mph on 5. PAGASA then initiated advisories on the system and named it Hanna, before the JTWC designated the system as Tropical Depression 09W and initiated advisories on the system, while it was at its 1-minute peak wind speeds of 55 km/h mph on 5. However, by this time Tokage was already interacting with Typhoon Ma-on, with Ma-on's outflow exposing Tokage's low level circulation center, and displacing convection to the west. The JMA, PAGASA and the JTWC then issued their final advisories on the system later that day as the remnants of Tokage was absorbed into Ma-on, due to the Fujiwhara effect late on July 15.

Also, the system had a highly symmetric radial outflow. The JTWC originally anticipated Nesat to become a category 4 typhoon on the SSHS with winds exceeding 130 kn (1-min sustained). However, because of a cold anomaly, the system only reached a maximum 1-min sustained wind speed of 115 kn.JTWC — Tropical Cyclone Advisory 14 – Typhoon Nesat http://weather.noaa.gov/pub/data/raw/wt/wtpn31.pgtw..txt Joint Typhoon Warning Center September 27, 2011 live https://web.archive.org/web/20010430085217/http://weather.noaa.gov/pub/data/raw/wt/wtpn31.pgtw..txt April 30, 2001 Early on September 27, Nesat made landfall over the Luzon region of Philippines.

At that time, it was located near the southern periphery of a deep layered subtropical steering ridge and moved towards the southwest and the winds further dropped to 85 kn because of land interaction.JTWC — Tropical Cyclone Advisory 16 – Typhoon Nesat http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201109270900.htm Joint Typhoon Warning Center September 28, 2011 dead https://archive.today/20240523113029/https://www.webcitation.org/621ycUxkz?url=http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201109270900.htm May 23, 2024 Though the system has maintained overall central deep convection, subsidence persisted along the northwest quadrant which caused further drop in wind speed. Upper level analysis indicated that Nesat was to the south of a ridge axis in an area of moderate vertical wind shear.JTWC — Tropical Cyclone Advisory 18 – Typhoon Nesat http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201109272100.htm Joint Typhoon Warning Center September 28, 2011 dead https://archive.today/20240523112951/https://www.webcitation.org/621ycIOZg?url=http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201109272100.htm May 23, 2024 The system continued to weaken with convective banding loosely wrapped into the partially exposed LLCC. The winds continued to drop and eventually reached 65 kn (1-min sustained) which made it a minimal typhoon on the SSHS. Though the weakening, Water vapour imagery showed that the typhoon was still maintaining excellent outflow towards the equator and improving outflow towards the pole.JTWC — Tropical Cyclone Advisory — Typhoon Nesat http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201109280900.htm Joint Typhoon Warning Center September 30, 2011 dead https://archive.today/20240523113149/https://www.webcitation.org/623Tp1kIp?url=http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201109280900.htm May 23, 2024 Nesat maintained a relatively large area of gale-force winds.

Because of the poor shapre and disorganization at the LLCC, the typhoon could only maintain a maximum 1-min sustained windspeed of 65 kn.JTWC — Tropical Cyclone Advisory 24 – Typhoon Nesat http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201109290900.htm Joint Typhoon Warning Center October 1, 2011 dead https://archive.today/20240523113351/https://www.webcitation.org/625GoDh2q?url=http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201109290900.htm May 23, 2024 Even after the landfall, Nesat maintained vigorous convection all around the LLCC and did not weaken too much when compared to the reactions after the Philippine landfall. There was a sea-surface temperature of approximately 28 C and a slight vertical wind shear of 10 kn near the system's center at that time. The JTWC anticipated the storm to gradually drift over the Gulf of Tonkin and make landfall over Vietnam with a 1-min sustained wind speed of at-least 50 kn.JTWC — Tropical Cyclone Advisory 26 – Typhoon Nesat http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201109292100.htm Joint Typhoon Warning Center October 1, 2011 dead https://archive.today/20240523113310/https://www.webcitation.org/625GnvuBG?url=http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201109292100.htm May 23, 2024 Early on September 30, Nesat made its final landfall over northern Vietnam with a 1-mim sustained windspeed of 55 kn and a well-defined, tightly wrapped LLCC, and soon it started weakening. The lowest air pressure recorded in Cô Tô during the typhoon was 981.4 hPa inHg 2 on out 5.

By the evening of September 27, at-least 7 people were reported to be killed and most of them in metropolitan Manila, a place already battered by heavy monsoonal rains. Similar to the Tulane University during Hurricane Katrina, the Manila Hospital moved patients from its ground floor which was flooded with neck-deep waters. Hospital generators were flooded and the building had no power since the typhoon arrived. Soldiers and police in trucks moved thousands of residents, most importantly the women and the children away from the Baseco shanty after many houses were washed away in the storm surge and floodwaters brought by Nesat. The typhoon made landfall before dawn triggering instant response. Authorities ordered more than a hundred thousand people across the country to flee from Typhoon Nesat's rains and wind gusts. Several schools and offices were shut and thousands were stranded after flight and ferry services were completely disrupted by the fierce storm. Nearly thirty-seven percent of Manila Electric Company's service area was left without power after high winds and heavy rains toppled power lines. Also, in Malabon, Navotas and Valenzuela the Manila Electric power company shut down power to prevent any accidents.September 2013 During the period when Nesat affected Vietnam, the highest sustained wind speed recorded on land was 25 m/s km/h mph 0 on out 5 at Cửa Ông (Quảng Ninh).

Nalgae rapidly intensified on September 30, and attained category 4 super typhoon status early on October 1, just before making landfall over Luzon. Due to land interaction and colder sea surface temperature in the South China Sea, the JMA downgraded Nalgae to a severe tropical storm on October 2, and then a tropical storm late on October 3. The JTWC downgraded Nalgae to a tropical depression on October 4, and the JMA also did it on the next day. Later on October 5, the remnant low of Nalgae dissipated. Striking the Philippines just days after Typhoon Nesat, Nalgae caused further damage across Luzon. Although first feared that Nalgae would cause much more damage to Luzon, which was severely affected by Typhoon Nesat, damage from the storm was not as anticipated to be lighter than Typhoon Nesat, which ironically is much weaker than Nalgae, but high winds and heavy rains from the storm caused widespread power outages and flooding that left many communities isolated. Nearly 2,900 homes were destroyed and approximately another 15,400 sustained damage. At least 18 people were killed by the storm and another 7 were reported as missing as of October 11.

But later that day, the depression began to weaken rapidly, as the storm moved southeastward. However, the JTWC issued a TCFA on the disturbance again early on December 12, because of a decrease in vertical wind shear.
