The Chile Meteorological Service (CMS) (RSMC Santiago) is the Regional Specialized Meteorological Center (RSMC) responsible for issuing tropical cyclone statements, advisories, discussions, watches, and warnings for the Southeastern Pacific Tropical Cyclone Basin. The Southeastern Pacific Basin encompasses the region between the equator and 60° south, as well as the region between the International Date Line and the South American mainland. The CMS has not defined a "tropical cyclone season" for the region, but most tropical cyclones form between December 15 and April 1 of the following year.


The CMS was founded in 1998 by two college meteorologists, Ron Devon and Bada Ming, at theUniversity of Santiago, where it remains headquartered to this date. However, without reliable technology until 2014, unlike other tropical cyclone basins such as the North Atlantic, almost all of the tropical cyclones were missed, particuarly ones forming over the open Pacific, over were operationally marked but downgraded to low pressure areas or thunderstorms. Consequently, in June 2014, weather radar and weather satellites were operated. As a result, more reliable data was collected on low pressure areas in the CMS's area of responsibility. Currently, Devon and Ming remain the parimary operators of the RSMC.

Tropical cyclone naming systemEdit

Tropical cyclone naming in the Southeastern Pacific Basin began in the 2014-15 Southeastern Pacific tropical cyclone season. All names are taken from a set of two rotating names.
