Weather Information Broadcasts

NOAA Weather Radio operates continuously
on the following frequencies:

  • 162.400 MHz (channel 1)
  • 162.475 MHz (channel 2)
  • 162.550 MHz (channel 3)
Your ability to tune in to any particular station depends on your position. NOAA transmitters are placed in frequency order- your ability to receive a weather broadcast for a particular area depends on your location relative to the transmitter. A broad, average range for frequency reception is 20 to 40 miles.

NOAA broadcasts current weather conditions such
as temperature, humidity, wave conditions, dew point, barometric pressure, wind speed and direction, and other weather information.

For more severe weather, NOAA uses the
following descriptions:


Small Craft Advisory: Observed or forecast winds of 18 to 33 knots--Small Craft Advisories may also be issued for hazardous sea conditions or lower wind speeds that may affect small craft operations. (note: There is no legal definition of the term "small craft".)


  • Gale Warning:¬†Observed or forecast winds of 34 to 47 knots
  • Storm Warning: Observed or forecast winds of 48 knots or greater.
  • Tropical Storm Warning: Observed or forecast winds of 34 to 64 knots or higher associated with a tropical storm.
