  Description:
    Abstract:
      This Historical North Atlantic Hurricane Tracks file of Major Storms with 
      Landfall in the United States contains the 6-hourly (0000, 0600, 1200, 
      1800 UTC) center locations and intensities for all major storms from 1851 
      through 2000.  Major storms are those that made landfall in the United 
      States and that were classified on the Saffir-Simpson Hurricane Scale as 
      category 3, 4, or 5 at the time of landfall.  Landfalling storms are 
      defined as those storms whose center is reported to have either crossed or 
      passed directly adjacent to the U.S. coastline, and which came ashore with 
      tropical storm intensity or greater (sustained surface winds of 34 knots 
      or 39 miles per hour or greater).
    Purpose:
      These data are intended for geographic display and analysis at the 
      national level, and for large regional areas.  The data should be 
      displayed and analyzed at scales appropriate for 1:2,000,000-scale data.  
      No responsibility is assumed by the National Oceanic and Atmospheric 
      Administration or the U.S. Geological Survey in the use of these data. 

    Supplemental_Information:

      file is available at

      storms was drawn.

      Specific accuracy information can be found in Neumann, C.J., B.R. 
      Jarvinen, C.J. McAdie and G.R. Hammer, 1999: Tropical Cyclones of the 
      North Atlantic Ocean, 1871-1999 (fifth revision).  NCDC/NHC Historical 
      Climatology Series 6-2, pp.11-14.  Similar standards and techniques were 
      applied to the data for 2000.
  Logical_Consistency_Report: 
    Over-water portions of storm tracks before 1944 are subject to considerable 
    uncertainties.  Aircraft reconnaissance of storms near critical areas was 
    introduced in 1944, and continuous weather satellite surveillance was 
    introduced in the mid-1960's.  These two developments mean that more recent 
    storm records have a higher degree of accuracy than those prior to 1944.

    No tests for logical consistency have been performed on this data set.
  Completeness_Report: 
    This data set contains all known Atlantic Basin (Gulf of Mexico, Caribbean 
    Sea, and North Atlantic Ocean) major hurricanes that made landfall in the 
    United States and that occurred between 1851 And 1999.  Major landfalling 
    hurricanes are those that were  classified on the Saffir-Simpson Hurricane 
    Scale as category 3, 4, or 5 at the time of landfall.

        locations were determined with a reasonable degree of accuracy.

    Process_Step:
      Process_Description: 
        Historical track information was downloaded from the National Hurricane 
        Center's Web site.  The textual information was formatted using a PERL 
        script written by the NOAA Coastal Services Center.  The file of was 
        then brought into ArcView as a table and converted to a shapefile with 
        attributes using an Avenue script.  This file contained all the 
        subtropical depressions and storms, tropical depressions and storms, and 
        all hurricanes, from 1851 through 2000.  (The file of all storms is 
        included in the National Atlas of the United States as huralll020.)

        The file of major landfalling hurricanes was created by first extracting
        all landfalling storms from the file of all storms, according to the
        landfall attribute field.  Then, landfall location and intensity 
        information for the resulting data set was extracted from the original 
        source file and added as a separate attribute.  Finally, the location 
        information was used to extract those storms that made landfall as major 
        hurricanes.

        Major hurricane tracks (described by Hurmjrl020.dbf)
      Entity_Type_Definition:
        The path followed by the center of a major landfalling hurricane.  A 
        major landfalling hurricane is one that made landfall in the United 
        States and that was classified on the Saffir-Simpson Hurricane Scale as 
        a category 3, 4, or 5 hurricane at the time of landfall.  A hurricane is 
        a warm-core tropical cyclone in which the maximum sustained surface wind 
        is 64 knots/74 mph or more.  A landfalling storm is defined as a storm 
        whose center is reported to have either crossed or passed directly 
        adjacent to the U.S. coastline, and which came ashore with tropical 
        storm intensity or greater.

        For example, Hurricane Andrew (1992) has a location code of 
        HR CFL4 BFL3 LA3, which means that Andrew made landfall as a category 4 
        hurricane on the southeast coast of Florida, crossed the peninsula and 
        exited as a category 3 hurricane on the southwest coast of Florida, 
        crossed the Gulf of Mexico and then made final landfall on the Louisiana 
        coast as a category 3 hurricane.
