Coverage Maps Notes
The coverage statistics and maps are calculated using a computer model and station data assuming ideal conditions. Coverage may be 5 to 10 percent below the computer predicted coverage for the following reasons:

The computer model is sensitive to antenna performance. Antenna performance is a function of local conditions, causing signals to be stronger signal level in some directions than others.

Most NWR stations are at existing antenna towers, provided at little or no cost. Placement of NWR antennas is dictated by the tower owner, which may result in a less than ideal set up.

The antenna may be affected by nearby structures or bodies of water.

In some special instances, the antenna may have been intentionally adjusted to be "directional" and provide better coverage to a specific area to the detriment of other areas.

Most of the stations employ equipment technology more than 20 years old. Because of variations in local site conditions, the performance of an individual transmitter and antenna may be less than predicted or expected.

Seasonal environmental conditions, such as icing or heavy rain, affect performance of a transmitter station and its various components, particularly those subject to continuous weather exposure.

The coverage maps are shown in a three color format, which relates to three estimated signal levels.
White: Signal level of greater than 18dBuV: Reliable coverage
Green: 0dBuV to 18dBuV: picking up a signal is possible but unreliable
Red: Less than 0dBuV: Unlikely to receive a signal.

General Information on NOAA Weather Radio

    NOAA Weather Radio is a Service of the National Oceanic and Atmospheric Administration (NOAA) of  the U. S. Department of Commerce.  As the "Voice of the National Weather Service," it provides continuous broadcasts of the latest weather information from local National Weather Service Offices.   Weather messages are repeated every 4 to 6 minutes and are routinely updated every 1 to 3 hours or more frequently in rapidly changing local weather. Most stations operate 24 hours daily. 

    The regular broadcasts are specifically tailored to the weather information needs of the people within the service area of the transmitter.  Other specialized information, such as hydrological forecasts and climatological data are also broadcast.

   During severe weather, National Weather Service broadcasters can interrupt the routine weather broadcasts and insert special warning messages concerning imminent threats to life and property.  The broadcaster can also add special signals to warnings that will trigger "alerting" features on especially equipped receivers. 

    NOAA weather radio currently broadcasts from over 400 FM transmitters on seven frequencies
on the VHF band, ranging from 162.400 to 162.550 mega hertz (MHz) in fifty states, Puerto Rico, the
Virgin Islands, Guam, and Saipan.  These frequencies are outside the normal AM or FM broadcast bands.
