Weatheradio.
You can listen to a weather channel or set your radio to alert you to emergency
weather broadcasts that interrupt routine broadcasts.
When you listen to weather channel, you cannot use your radio in scan mode or
for twoway communications.
Both NOAA and Environment Canada have transmitters located throughout the
United States and Canada, respectively. These transmitters broadcast watches,
forecasts, and other information 24 hours a day.
Note: NOAA weather radio stations are assigned to cover specific areas and
service may be limited. Please check with your local weather office for
frequency and details, or visit www.nws.noaa.gov/nwr in the US or   
www.mscsmc.ec.gc.ca/cd/factsheets/wxradio in Canada to view the
appropriate transmitter for your area. The use of the NOAA logo does not
