NOAA US County and Zone Codes

From WeatherWiki

It's often useful when working with NOAA information to know your County and Zone code numbers. The following maps will help you locate your zone.

NOAA Zone Map

The following contains all United States zones:

This file is an ASCII "dump" in pipe ("|") delimited form, of a "master" shapefile maintained by AWIPS GIS Map Group (AGMG) for the maintenance of County, Public Forecast Zones, CWA boundaries, and Time zones. Each record represents a single polygon within the master file. Multiple polygons may exist for the same zone/county that contain the same attributes, but the latitude and longitude fields will be different as they are the centroid of the polygon. No attempt has been made to remove these seemingly duplicate entries from this text file. In addition, the coastal and offshore marine zone shapefiles are also "dumped" to this file.
