The National Hurricane Center (NHC), located at Florida International University in Miami, Florida, is the division of the 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. - Source: Wikipedia
