NWS suggests listeners change the batteries in their receivers in the spring and fall when Daylight Savings Time begins and ends.
Weather Radio All Hazards (NWR) is a nationwide network
of radio stations broadcasting continuous weather information
from the nearest National
Weather Service office. NWR broadcasts official
warnings, watches, forecasts and other hazard information
24 hours a day, 7 days a week.
Working with the Federal
Communication Commission's Emergency
Alert System, NWR is an all hazards radio network, making
it your single source for comprehensive weather and emergency information.
In conjunction with emergency managers
and other public officials, NWR broadcasts warning and post-event
information for all types of hazards including natural events such
as earthquakes and avalanches, environmental accidents such as chemical
releases or oil spills, and public safety issues such as a child abduction or 911 telephone outage.
Known as the "Voice of NOAA's National Weather Service," NWR is
provided as a public service by the National
Oceanic and Atmospheric Administration, part of the Department
of Commerce. NWR numbers 1000 transmitters,
covering all 50 states, adjacent coastal waters, Puerto Rico, the
U.S. Virgin Islands, and the U.S. Pacific Territories. NWR requires
radio receiver or scanner capable of picking up the signal.
Broadcasts are found in the VHF public service band at these seven
frequencies (MHz) listed below.
