Pacific typhoon seasons 2009, 2010, 2011 |
The 2011 Pacific typhoon season is an upcoming event in which tropical cyclones form in the Western Pacific Ocean. The season will run throughout 2011 with most tropical cyclones forming between May and November. 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, (40 mph) 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. On average, 27 storms form in this basin every year.
Seasonal forecasts
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.

Storm Names
Within the Northwestern Pacific Ocean, there are two separate agencies who assign names to tropical cyclones which often results in a cyclone having two names. The Japan Meteorological Agency names tropical cyclones should they be judged to have 10-minute sustained windspeeds of 65 km/h, (40 mph), to the north of the equator between the 180° and 100°E. 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°E-25°E even if the cyclone has had a name assigned to it by the Japan Meteorological Agency. Names in bold are storms that are currently active, and unused names are marked in gray.
International names
Tropical Cyclones are named from the following lists by the Regional Specialized Meteorological Centre in Tokyo, Japan, once they reach tropical storm strength. Names are contributed by members of the ESCAP/WMO Typhoon Committee. Each of the 14 nations or territories submitted 10 names, which are used in alphabetical order, by the English name of the country. The next 24 names on the naming list are listed here.

Philippines
The Philippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility. PAGASA assigns names to tropical depressions that form within their area of responsibility and any tropical cyclone that might move into their area of responsibility. Should the list of names for a given year prove to be insufficient, names are taken from an auxiliary list, the first 10 of which are published each year before the season starts.

Season effects
This table lists all the storms that developed in the western Pacific Ocean to the west of the International Date Line during the 2010 season. It includes their intensity, duration, name, landfalls, deaths, and damages. All damage figures are in 2011 USD. Damages and deaths from a storm include when the storm was a precursor wave or extratropical low.
