Description: The working best track wind swath is created by accumulating the best track wind radii over the course of an ongoing tropical cyclone. The working best track wind swath will generally not exactly match the radii contained in the tropical cyclone advisories. This is because all of the data in a working best track are subject to modification during the life cycle of the the cyclone. (Note: The "working best track" represents the forecasters' best estimates of the location, intensity, and size of a tropical cyclone while the cyclone is ongoing. After the life cycle is complete, forecasters prepare a "final best track", using data that might not have been available operationally, and it is the final best track that represents NHC's official historical record for the cyclone.)
Description: Original GIS polygon dataset derived from the 1990 Census Bureau's TIGER files. The original scale of the data is 1:100,000 and covers the entire state of Mississippi. Using coding from the TIGER files, this dataset includes only county boundaries. **** Edits ***1 - Data was updated in April 2007 using 1:24,000 USGS Digital Raster Graphics. 2 - Additional edits were made in October 2010 from input from Lamar County E911 Coordinator Freda Rocker. 3 - Gulf Coastal Boundary was updated in May 2015 by MARIS staff using the guidance of MDEQ Office of Geology's Mississippi/Louisiana border based using 1906 Supreme Court decision, MDEQ’s Offshore Mineral Lease map, and the US Bureau of Ocean Energy, Mapping and Boundary Branch's Submerged Lands Act 2011 Boundary.
