The National Hurricane Center (NHC), located at Florida International University in Miami, Florida, is the division of the United States' National Weather Service responsible for tracking and predicting weather systems within the tropics between the Prime Meridian and the 140th meridian west poleward to the 30th parallel north in the northeast Pacific ocean and the 31st parallel north in the northern Atlantic ocean. Its Tropical Analysis and Forecast Branch (TAFB) routinely issues marine forecasts, in the form of graphics and high seas forecasts, for this area year round, with the Ocean Prediction Center having backup responsibility for this unit. 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. Research conducted to improve operational forecasts is done through the Hurricane Forecast Improvement Project (HFIP) and Joint Hurricane Test Bed (JHT) initiatives.
During the Atlantic and northeast Pacific hurricane seasons, the Hurricane Specialists 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 the appropriate 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 Regional Specialized Meteorological Center for the North Atlantic and eastern Pacific, making it the central clearinghouse for all tropical cyclone forecasts and observations occurring in these areas. If the center loses power or becomes incapacitated in some manner, the Central Pacific Hurricane Center backs tropical cyclone advisories and tropical weather outlooks for the northeast Pacific ocean while the Hydrometeorological Prediction Center backs up tropical cyclone advisories and tropical weather outlooks for the north Atlantic ocean.

Famous quotes containing the words national, hurricane and/or center:
“All men are lonely. But sometimes it seems to me that we Americans are the loneliest of all. Our hunger for foreign places and new ways has been with us almost like a national disease. Our literature is stamped with a quality of longing and unrest, and our writers have been great wanderers.”
—Carson McCullers (1917–1967)
“Staid middle age loves the hurricane passions of opera.”
—Mason Cooley (b. 1927)
“The greatest part of each day, each year, each lifetime is made up of small, seemingly insignificant moments. Those moments may be cooking dinner...relaxing on the porch with your own thoughts after the kids are in bed, playing catch with a child before dinner, speaking out against a distasteful joke, driving to the recycling center with a week’s newspapers. But they are not insignificant, especially when these moments are models for kids.”
—Barbara Coloroso (20th century)
