2015 Pacific typhoon season#Other systems

During the year 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. These agencies included the Tropical Storm Risk (TSR) Consortium of the University College London, Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) and the Taiwan's Central Weather Bureau. Some of the forecasts took into consideration what happened in previous seasons and the El Niño Conditions that were observed during the year. The first forecast of the year was released by PAGASA during January 2015, within its seasonal climate outlook for the period January – June. The outlook noted that one to two tropical cyclones were expected between January and March while one to three were expected to develop or enter the Philippine Area of Responsibility between April and June.

During March the Hong Kong Observatory predicted that the typhoon season in Hong Kong, would be near normal with four to seven tropical cyclones passing within {{convert|500|km|mi|round=5|abbr=on}} of the territory compared to an average of six.{{cite web |title=Speech by Mr Shun Chi-ming, Director of the Hong Kong Observatory March 17, 2014 |date=March 17, 2014 |access-date=April 6, 2015 |url=http://www.weather.gov.hk/dhkovoice/speech20150323e.pdf |url-status=live |archive-date=October 6, 2014 |archive-url=https://web.archive.org/web/20141006120642/http://www.weather.gov.hk/dhkovoice/speech20140317e.pdf |publisher=Hong Kong Observatory |author=Chi-ming, Shun |df=mdy}} Within its Pacific ENSO Update for the 2nd quarter of 2015, NOAA's Pacific El Niño–Southern Oscillation Applications Climate Center, noted that the risk of a damaging tropical cyclone in Micronesia was "greatly enhanced" by El Niño.{{cite journal |author1=Pacific El Niño–Southern Oscillation (ENSO) Applications Climate Center |title=Pacific ENSO Update: 2nd Quarter 2015 |date=May 29, 2015 |volume=21 |issue=2 |url=http://www.weather.gov/media/peac/PEU/PEU_v21_n2.pdf |publisher=United States National Oceanic and Atmospheric Administration's National Weather Service |archive-url=https://web.archive.org/web/20160304070616/http://www.weather.gov/media/peac/PEU/PEU_v21_n2.pdf |archive-date=March 4, 2016 |url-status=live |df=mdy}} As a result, they forecasted that the risk of a typhoon severely affecting Micronesia was high, with most islands predicted to have a "1 in 3 chance" of serious effects from some combination of high winds, large waves and extreme rainfall from a typhoon. They also predicted that there was a near 100% chance of severe effects from a typhoon somewhere within Micronesia. On May 6, Tropical Storm Risk issued their first forecast for the season and predicted that the season, would be the most active since 2004 with activity forecast to be above average. Specifically it was forecast that 27 tropical storms, 17 typhoons, and 11 intense typhoons would occur, while an ACE Index of 400 was also forecasted.

Ahead of the Thailand rainy season starting during May, the Thai Meteorological Department predicted that one or two tropical cyclones would move near Thailand during 2015.{{cite web |title=The 2015 Rainy Season Climate Expectation of Thailand |archive-url=https://web.archive.org/web/20150724113044/http://www.tmd.go.th/en/seasonal_forecast.php |archive-date=July 24, 2015 |access-date=July 24, 2015 |url=http://www.tmd.go.th/en/seasonal_forecast.php |date=June 26, 2015 |publisher=Thai Meteorological Department |url-status=live |df=mdy}} The first of the two tropical storms was predicted to pass near Upper Thailand in either August or September, while the other one was expected to move to the south of Southern Thailand during November. On June 30, Taiwan's Central Weather Bureau predicted that 28–32 tropical storms would develop over the basin, while two — four systems were expected to affect Taiwan itself. During July, Paul Stanko of the United States National Weather Service Weather Forecast Office in Tiyan, Guam, called for tropical cyclone activity to be above average.{{cite journal |author=Pacific El Niño–Southern Oscillation (ENSO) Applications Climate Center |volume=21 |issue=3 |url=http://www.weather.gov/media/peac/PEU/PEU_v21_n3.pdf |title=Pacific ENSO Update: 3rd Quarter 2015 |publisher=United States National Oceanic and Atmospheric Administration's National Weather Service |archive-url=https://web.archive.org/web/20151120045953/http://www.weather.gov/media/peac/PEU/PEU_v21_n3.pdf |archive-date=November 20, 2015 |url-status=live |access-date=August 15, 2015 |date=August 14, 2015 |df=mdy}} He also predicted that several records would be set for the number of major typhoons in the western Pacific, tropical storms, typhoons and major typhoons in Micronesia. PAGASA subsequently predicted within its July — December seasonal climate outlook, that seven to ten tropical cyclones were likely to develop and/or enter the Philippine area of responsibility between July and September, while three to five were predicted for the October–December period. On July 16, the Guy Carpenter Asia-Pacific Climate Impact Centre (GCACIC) and the City University of Hong Kong's School of Energy, released their seasonal forecast for the period between June 1 – November 30.{{cite report |publisher=City University of Hong Kong |title=2015 Western North Pacific Basin Tropical Cyclone Predictions |author=Guy Carpenter Asia-Pacific Climate Impact Center |date=July 16, 2015 |archive-date=July 24, 2015 |url=http://www.cityu.edu.hk/gcacic/Research_Brief_201501.pdf |access-date=July 24, 2015 |author2=School of Energy and Environment |archive-url=https://web.archive.org/web/20150724162602/http://www.cityu.edu.hk/gcacic/Research_Brief_201501.pdf |url-status=live |df=mdy}} They predicted that 19.9 tropical cyclones would develop during the period with 10.3 of these going on and making landfall compared to averages of 23.0 and 17.4 tropical cyclones. They further predicted that both the Korea — Japan region and that Taiwan and the Eastern Chinese provinces of Jiangsu, Shanghai, Zhejiang, Fujian would see three of these landfalls each. Vietnam, the Philippines and the Southern Chinese provinces of Guangdong, Guangxi and Hainan were forecasted to see four landfalling tropical cyclones. On August 5, Tropical Storm Risk issued their final forecast for the season and predicted that 2015 would be a hyperactive season. Specifically it was forecast that 30 tropical storms, 20 typhoons, 13 intense typhoons would occur, while an ACE Index of 448 was also forecasted.

Most of the 27 tropical cyclones affected Micronesia, because of the record-tying 2014–16 El Niño event. 2015 opened with Tropical Depression Jangmi (Seniang) from the previous season active within the Sulu Sea, to the north of Malaysia, on January 1, 2015. The system subsequently moved south-eastward, made landfall on Malaysia, and dissipated later that day. However, the official first tropical cyclone of the season was a minor tropical depression, in the same place where Jangmi persisted on January 2, but dissipated two days later.{{cite web |title=Monthly Global Tropical Cyclone Summary January 2015 |url=http://australiasevereweather.com/cyclones/2015/trak1501.htm |work=Summaries and Track Data |publisher=Australiansevereweather.com |access-date=February 18, 2015 |author=Padgett, Gary |author2=Boyle, Kevin |author3=Chunliang, Huang |date=January 2015}} Tropical Storm Mekkhala, on January 13, developed and approached the Philippines where it caused minor damages and also notably interrupted Pope Francis's visit to the country. In early-February, Typhoon Higos developed further east of the basin and reached peak strength of a Category 4 typhoon.{{#tag:ref|Tropical cyclones reaching Category 3 ({{convert|111|mph|km/h|disp=or|sp=us}}) and higher on the five-level Saffir–Simpson wind speed scale are considered major hurricanes.|group="nb"}} Higos became the strongest typhoon on record in the month of February when it broke the record of Typhoon Nancy (1970),{{cite web |title=Monthly Global Tropical Cyclone Summary February 2015 |url=http://australiasevereweather.com/cyclones/2015/trak1502.htm |work=Summaries and Track Data |publisher=Australiansevereweather.com |access-date=March 10, 2015 |author=Padgett, Gary |author2=Boyle, Kevin |author3=Chunliang, Huang |date=February 2015}} and was in turn surpassed by Typhoon Wutip in 2019.

In September, Tropical Storm Etau brought flooding in much of Japan, with damages at least US$100 million. Tropical Storm Vamco made landfall over in Vietnam and caused moderate impact and damages. Typhoon Dujuan, similar to Soudelor, impacted China and Taiwan with total damages of $660 million as a Category 4 super typhoon.{{cite web |title=Monthly Global Tropical Cyclone Summary September 2015 |url=http://australiasevereweather.com/cyclones/2016/trak1509.htm |work=Summaries and Track Data |publisher=Australiansevereweather.com |access-date=December 29, 2015 |author=Padgett, Gary |author2=Boyle, Kevin |author3=Chunliang, Huang |date=September 2015}} In early October, Typhoon Mujigae rapidly intensified into a Category 4 typhoon when it made landfall over Zhanjiang, spawning a tornado causing 29 deaths and over US$4 billion in damages.

Haishen knocked down several fruit trees on Fananu, while the heavy rains were considered to be a positive blessing, as they restored water levels on the island, that had been damaged a few days earlier by Maysak.

On Majuro atoll in the Marshall Islands, high winds from Nangka tore roofs from homes and downed trees and power lines. Nearly half of the nation's capital city of the same name were left without power. Tony deBrum, the Marshall Island's foreign minister, stated "Majuro [is] like a war zone." At least 25 vessels in the island's lagoon broke loose from or were dragged by their moorings. Some coastal flooding was also noted.{{cite news |agency=Agence France-Presse |publisher=Australian Broadcasting Corporation |date=July 4, 2015 |access-date=July 4, 2015 |title=Chaotic unseasonal storms strike Marshall Islands and Guam as eight systems threaten western Pacific |url=http://www.abc.net.au/news/2015-07-04/chaotic-unseasonal-storms-strike-marshall-islands-and-guam/6595124}}
