To maximize continuity, the CIMSS Tropical Cyclone group uses official TC warning
and forecast products from the
NOAA/National Hurricane Center (NHC), the
NOAA/Central Pacific Hurricane Center (CPHC), and the
Joint Typhoon Warning Center (JTWC) at Pearl Harbor, HI.
Tropical cyclones may be recognized by other official Regional Specialized Meteorological
Centers (RSMC) and Tropical Cyclone Warning Centers (TCWC) but not recognized by the JTWC,
leading to a possible discrepancy between TCs displayed on our page and other Centers around the world.
The official RSMC are :
• Southwest Pacific Ocean: RSMC Nadi - Tropical Cyclone Centre / Fiji Meteorological Service (Nadi, Fiji)
• Southwest Indian Ocean: RSMC La Reunion - Tropical Cyclone Centre / Meteo-France (La Reunion Island, French Overseas Department)
• Bay of Bengal and Arabian Sea: RSMC - Tropical Cyclones New Delhi / India Meteorological Department (New Delhi, India)
• Western North Pacific Ocean and South China Sea: RSMC Tokyo - Japan Meteorological Agency (Tokyo, Japan)
• Central North Pacific Ocean: RSMC Honolulu - Central Pacific Hurricane Center (Honolulu, Hawaii, USA)
• Northeast Pacific Ocean, Gulf of Mexico, Caribbean Sea, and north Atlantic Ocean: RSMC Miami - National Hurricane Center
The official TCWC are :
• Southeast Indian Ocean (south of 10S): TCWC - Perth / Bureau of Meteorology
• Arafura Sea and Gulf of Carpentaria: TCWC - Darwin / Bureau of Meteorology
• Coral Sea: TCWC - Brisbane / Bureau of Meteorology
• Solomon Sea and Gulf of Papua: TCWC - Port Moresby / National Weather Service forecast office, Papua New Guinea
• Tasman Sea: TCWC - Wellington, New Zealand / Meteorological Service of New Zealand Limited
• Southeast Indian Ocean (north of 10S): TCWC - Jakarta / Meteorology and Geophysical Agency of Indonesia
"Invest" areas are regions of disturbed weather of particular interest to either of those two
organizations. These areas are provided to us by the
Tropical Cyclone Team at the
Naval Research Laboratory in Monterey, CA.
