The National Hurricane Center ( NHC ) is a division of the Tropical Prediction Center affiliated with the National Weather Service of the United States and subordinated to the National Oceanic and Atmospheric Administration (NOAA). The seat is in Miami , Florida .

Function and history

The foundation goes back to an instruction of the American President William McKinley on December 5, 1898, with which the National Weather Service was commissioned to set up an early warning network to protect against tropical cyclones. With the advances in communication and forecasting technology, the competencies were finally brought together in Miami and in 1967 the NHC was given responsibility for the entire North Atlantic.

Its job is to monitor and predict the likely behavior of tropical cyclones in the Atlantic and Pacific Oceans east of longitude 140 west of Greenwich. Although it is a US government agency , based on the decision of the World Meteorological Organization , the NHC is the central information point for the area whether or not a storm threatens the United States area. In 1988 the Eastern Pacific Hurricane Center in San Francisco was dissolved and the area was added to the NHC in Miami.

In 1992, Hurricane Andrew blew the WSR-57 weather radar and wind gauges from the roof of the building that was then the headquarters of the NHC. The weather radar was replaced by NEXRAD , and in 1995 the agency moved to a new hurricane-proof facility on the grounds of Florida International University .

Former director of the National Hurricane Center, Bob Simpson, is co-author of the five-point Saffir-Simpson Hurricane Wind Scale , which is used to assess the strength of hurricanes.

If a tropical storm or hurricane is expected within 36 hours, the NHC will issue warnings through the news media and NOAA weather radio . The hurricane specialists at the NHC work from the beginning of May to the end of November in continuous eight-hour shifts and observe the weather developments in the Atlantic and Eastern Pacific. (The situation in the Pacific west of 140th longitude is monitored by the Joint Typhoon Warning Center .) As soon as a depression develops, they issue warnings every six hours. When the storm threatens land, the warnings are published more often. In doing so, they work together with responsible bodies in the countries concerned. Each notification is signed by the hurricane predictive specialist by his or her last name, sometimes making joint predictions with other NHC personnel.
