The Technology and Science Branch TSB provides technical support for the center, which includes new infusions of technology from abroad. The Chief, Aerial Reconnaissance Coordination, All Hurricanes CARCAH unit tasks planes, for research and operational purposes, to tropical cyclones during the Atlantic hurricane season and significant weather events, including snow storms, during winter and spring. During the Atlantic and northeast Pacific hurricane seasons, the Hurricane Specialist Unit HSU issues routine tropical weather outlooks for the northeast Pacific and northern Atlantic oceans. When tropical storm or hurricane conditions are expected within 48 hours, the center issues watches and warnings via the news media and National Oceanic and Atmospheric Administration NOAA Weather Radio. Although the NHC is an agency of the United States, the World Meteorological Organization has designated it as the Regional Specialized Meteorological Center for the North Atlantic and eastern Pacific, making it the clearinghouse for tropical cyclone forecasts and observations occurring in these areas. If the NHC loses power or becomes incapacitated, the Central Pacific Hurricane Center backs tropical cyclone advisories and tropical weather outlooks for the northeast Pacific Ocean while the Weather Prediction Center backs up tropical cyclone advisories and tropical weather outlooks for the North Atlantic Ocean. After his death, hurricane warning services were assumed by the United States Signal Corps and United States Weather Bureau over the next decade, first based in Jamaica in and Cuba in before shifting to Washington, D. This responsibility passed to regional hurricane offices in , and the concept of the Atlantic hurricane season was established to keep a vigilant lookout for tropical cyclones during certain times of the year. Hurricane advisories issued every six hours by the regional hurricane offices began at this time. The Jacksonville hurricane warning office moved to Miami, Florida , in The National Hurricane Research Project , begun in the s, used aircraft to study tropical cyclones and carry out experiments on mature hurricanes through its Project Stormfury.

The National Hurricane Center and Central Pacific Hurricane Center's Tropical Cyclone Reports TCRs contain information on all tropical and subtropical cyclones that have occurred within the Atlantic, eastern Pacific, and central Pacific basins, including synoptic history, meteorological statistics, casualties and damages, and the post-analysis best track six-hourly positions and intensities. Beginning in , comprehensive versions of these reports will continue to be provided for all tropical cyclones in which coastal watches and warnings were in effect or direct fatalities were reported, and for other select storms with significant public or research interest e. The abbreviated TCRs also contain the full suite of tables and figures that are included in the comprehensive reports. Tropical cyclones include depressions, storms and hurricanes. Tropical depressions included below are those that did not reach tropical storm strength. Potential tropical cyclones listed below are disturbances that NHC issued advisories on based on their threat to land, but which failed to develop into tropical cyclones. Atlantic Eastern Pacific Central Pacific. Supplemental observations from Ian are available here. Julia updated 15 Mar Ian updated 21 Apr Disclaimer Information Quality Help Glossary.

Since , Atlantic tropical storms had been named from lists originated by the National Hurricane Center. They are now maintained and updated through a strict procedure by an international committee of the World Meteorological Organization. The six lists above are used in rotation and re-cycled every six years, i. The only time that there is a change in the list is if a storm is so deadly or costly that the future use of its name for a different storm would be inappropriate for reasons of sensitivity. If that occurs, then at an annual meeting by the WMO committee called primarily to discuss many other issues the offending name is stricken from the list and another name is selected to replace it. Several names have been retired since the lists were created. Here is more information on the history of naming tropical cyclones and retired names. If a storm forms during the off-season, it will take the next name in the list based on the current calendar date.

A tropical cyclone is a rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has a closed low-level circulation. Tropical cyclones rotate counterclockwise in the Northern Hemisphere. They are classified as follows: Tropical Depression: A tropical cyclone with maximum sustained winds of 38 mph 33 knots or less.
