National Hurricane Center (NOAA)
The US National Hurricane Center is the division of National Weather Service's Tropical Prediction Center responsible for tracking and predicting the likely behavior of tropical depressions, tropical storms and hurricanes.
When tropical storm or hurricane conditions are expected within 36 hours, the center issues the appropriate watches and warnings via the news media and NOAA Weather Radio. Although an agency of the United States, the World Meteorological Organization has designated the NHC as Regional Specialized Meteorology Center for the North Atlantic and eastern Pacific. As such, the NHC is the central clearinghouse for all tropical cyclone forecasts and observations occurring in these areas, regardless of their effect on the US.
The National Hurricane Center has its roots in an 1898 declaration by then-President William McKinley for the Weather Bureau (now the National Weather Service) to establish a hurricane warning network. As communications and forecasting evolved, responsibility for issuing hurricane warnings was eventually centralized in the Miami Weather Bureau office.
The Miami office was designated the National Hurricane Center in 1967, and given responsibility for Atlantic tropical cyclones. In 1984, the NHC was separated from the Miami Weather Service Forecast Office, which was given the responsibility of handling standard weather forecasting and observation for southeastern Florida.
In 1992, Hurricane Andrew blew the WSR-57 weather radar and the anemometer off the roof of Gables One Tower, then the location of the NHC's offices. The radar was replaced with a WSR-88D NEXRAD system. In 1995, the NHC moved into a new hurricane resistant facility on the campus of Florida International University.
Former NHC Director Bob Simpson was co-creator of the Saffir-Simpson Hurricane Scale.
