2013 Pacific typhoon season

The 2013 Pacific typhoon season was an above-normal Pacific typhoon season.
Seasonal forecasts.
During each season, many 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 certain country. These agencies include the Tropical Storm Risk  Consortium of the University College London, Philippine Atmospheric, Geophysical and Astronomical Services Administration and the Vietnamese National Center for Hydro Meteorological forecasts .
Storm names.
Within the North-western Pacific Ocean, both the Japan Meteorological Agency (JMA) and the Philippine Atmospheric, Geophysical and Astronomical Services Administration assign names to tropical cyclones that develop in the Western Pacific, which can mean a tropical cyclone has two names. The Japan Meteorological Agency's RSMC Tokyo — Typhoon Center assigns international names to tropical cyclones on behalf of the World Meteorological Organization's Typhoon Committee, should they be judged to have 10-minute sustained windspeeds of . While 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 an international name given to it. The names of significant tropical cyclones are retired, by both PAGASA and the Typhoon Committee. Should the list of names for the Philippine region all be used, then names will be taken from an auxiliary list. The first ten of these names are made before the start of the season. Unused names are marked in .
International names.
During the season 29 tropical storms developed in the Western Pacific and each one was named by the JMA, when the system was judged to have 10-minute sustained windspeeds of . The JMA selected the names from a list of 140 names, that had been developed by the 14 members nations and territories of the ESCAP/WMO Typhoon Committee. During the season the names Leepi and Mangkhut were used for the first time, after they had replaced the names Xangsane and Durian, which were retired after the 2006 season.
After the season the Typhoon Committee retired the names "Sonamu", "Utor", "Fitow" and "Haiyan" from its naming lists, and in February 2015, the names were subsequently replaced with "Jongdari", "Barijat", "Mun" and "Bailu" for future seasons.
Philippines.
During the season PAGASA used its own naming scheme for the 25 tropical cyclones, that either developed within or moved into their self-defined area of responsibility. The names were taken from a list of names, that had been last used during 2009 and was used again during 2017. The names Fabian, Odette and Paolo were used for the first time during the year after the names Ondoy, and Pepeng were retired. The names Wilma, Yolanda, and Zoraida were also used for the first time (and only in the case of Yolanda).
After the season the names Labuyo, Santi and Yolanda were retired by PAGASA, as they had caused over 300 deaths and over PhP1 billion in damages. They were soon replaced on the list with Lannie, Salome and Yasmin.
Season effects.
This table lists all the storms that developed in the northwestern Pacific Ocean west of the International Date Line and north of the equator during 2013. It includes their intensity, duration, name, areas affected, deaths, and damage totals. Classification and intensity values are based on estimations conducted by the JMA. All damage figures are in 2013 USD. Damages and deaths from a storm include when the storm was a precursor wave or an extratropical low.
