# Tropical cyclones in 2006

Throughout 2006, 133 tropical cyclones formed in seven bodies of water known as tropical cyclone basins. Of these, 80 have been named, including two tropical cyclones in the South Atlantic Ocean, and a tropical cyclone in the Mediterranean Sea, by various weather agencies when they attained maximum sustained winds of 65 km/h (40 mph). The strongest storms of the year were Typhoon Yagi in the Western Pacific, and Cyclone Glenda of the Australian region. The deadliest and costliest storms of the year were a series of five typhoons that struck the Philippines and China; Chanchu, Bilis, Saomai, Xangsane, and Durian, with most of the damage being caused by Durian of November. So far, 27 Category 3 tropical cyclones formed, including five Category 5 tropical cyclones in the year. The accumulated cyclone energy (ACE) index for the 2006 (seven basins combined), as calculated by Colorado State University was 761 units.
Tropical cyclones are primarily monitored by a group of ten warning centres, which have been designated as a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC) by the World Meteorological Organization. These are the United States National Hurricane Center (NHC) and Central Pacific Hurricane Center, the Japan Meteorological Agency (JMA), the India Meteorological Department (IMD), Météo-France, Indonesia's Badan Meteorologi, Klimatologi, dan Geofisika, the Australian Bureau of Meteorology (BOM), Papua New Guinea's National Weather Service, the Fiji Meteorological Service (FMS) as well as New Zealand's MetService. Other notable warning centres include the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the United States Joint Typhoon Warning Center (JTWC), and the Brazilian Navy Hydrographic Center.

## Global atmospheric and hydrological conditions

There is a strong El Niño in this year.

## Summary

In the Northern Hemisphere, 10 tropical cyclones have developed or formed in the North Atlantic Ocean basin, 25 in the Eastern and Central Pacific (including one unofficial subtropical cyclone), 40 in the Western Pacific (including three unofficial tropical cyclones), and 12 in the North Indian (including one unofficial deep depression), totaling to 88 official and 6 unofficial tropical cyclones in the Northern Hemisphere, including one official and one unofficial tropical cyclones in the Mediterranean Sea.
In the Southern Hemisphere, 11 tropical cyclones have developed or formed in the South-West Indian Ocean basin, 19 in the South-Central Pacific/Fiji Region, 14 in the South-East Indian/Southwestern Pacific/Australian Region, and including 2 in the South Atlantic/Southeastern Pacific, thus totaling to 46 tropical cyclones in the Southern Hemisphere.
In the whole world combined, 134 tropical cyclones have developed throughout the whole world, including 6 unofficial systems, equaling 140 total tropical cyclones.

## Systems
### January

During January 2006, a total of 12 tropical cyclones have developed in tropical cyclone basins. Of those, 7 were named, with 6 of those named systems having tropical storm-equivalent force winds, in ten or three-minute sustained wind speeds. Tropical Storm Zeta from the extremely hyperactive 2005 Atlantic hurricane season became only the second of two tropical storms in the Atlantic to have spanned two different calendar years, with the other being Hurricane Alice of 1954–55. Speaking, Cyclones Tam and Clare were the only tropical cyclones in January 2006 to have known damage totals, even though Boloetse was the most severe and deadliest in the month. Boloetse was also the strongest and most intense tropical cyclone of the month, peaking with 10-minute sustained winds of 100 mph and pressure dropping to 950 hPa/mbar.
