National Hurricane Center August 1, 2008 vector digital data http://www.nhc.noaa.gov/gis The NHC official track forecast points in shapefile format is an experimental products that the National Hurricane Center is testing during the 2008 hurricane season. The points represent the official NHC forecast locations of the center of a tropical cyclone. Forecast center positions are given for projections valid 12, 24, 36, 48, 72, 96, and 120 h after the forecast's nominal initial time, provided that a closed surface wind circulation is expected to exist at the forecast projection time. It is important to remember that tropical cyclone track forecasts are subject to error, and that the effects of a tropical cyclone can span many hundreds of miles from the center. The points represent the official NHC forecast locations of the center of a tropical cyclone. 080601/0900 Forecast Advisory Date/Time Complete None planned -95.500000 -90.099998 18.299999 18.000000 None Hurricane Hurricane Track Tropical Storm Subtropical storm Subtropical depression Tropical disturbance Tropical Wave Tropical low Extratropical storm Major hurricane Tropical cyclone Subtropical cyclone None United States Atlantic North Atlantic Basin Gulf of Mexico Caribbean Sea Pacific Islands Eastern North Pacific Basin None None.
