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.

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. Tropical Storm: A tropical cyclone with maximum sustained winds of 39 to 73 mph 34 to 63 knots. Hurricane: A tropical cyclone with maximum sustained winds of 74 mph 64 knots or higher. In the western North Pacific, hurricanes are called typhoons; similar storms in the Indian Ocean and South Pacific Ocean are called cyclones. Major Hurricane: A tropical cyclone with maximum sustained winds of mph 96 knots or higher, corresponding to a Category 3, 4 or 5 on the Saffir-Simpson Hurricane Wind Scale. Tropical cyclones forming between 5 and 30 degrees North latitude typically move toward the west.
