This nowCOAST™ map service provides maps depicting the administrative boundaries of NOAA/NWS and some of its federal partners including USCG and USACE, as well as Air Route Traffic Control Center (ARTCC) boundaries for the National Airspace System (NAS). The service also includes the geographic breakpoints (geographic locations) along the U.S. coast used by NOAA/NWS National Hurricane Center (NHC) when issuing tropical cyclone watches and warnings along the immediate coastline. The administrative boundaries are updated when changes are made by the appropriate federal agencies to the boundaries or breakpoints.
The immediate coastline placed under NHC tropical storm or hurricane watches or warnings are identified through the use of breakpoints. A tropical cyclone breakpoint is defined as an agreed upon coastal location that can be chosen as one of two specific end points or designated places between which a tropical storm/hurricane watch/warning is in effect. NWS designates these locations along the U.S. East, Gulf, and California coasts, Puerto Rico, and Hawaii. For more information on breakpoints please see http://www.nhc.noaa.gov/breakpoints_graphics.shtml.
