Weather radio

Weather radios are generally sold in two varieties: home (stationary) or portable use. Portable models commonly offer specialized features that make them more useful in case of an emergency. Some models use crank power, in addition to mains electricity and batteries, in case of a power outage. DT-400W (10711303835) Smaller hand-held weather receivers generally do not support the Specific Area Message Encoding (SAME) alert type encoding (though there are some that do) but allow hikers and other explorers to listen to weather reports without packing a heavy and bulky base station radio. Some models have a built-in flashlight and can double as a cellphone charger. Some also serve as a more general emergency radio and may include multiband and two-way communication capability. "Scanner" radios designed to continuously monitor the VHF-FM public service band are already able to receive weather channels. Besides SAME alerting capability, modern weather radio receivers, especially those that are compliant with CTA standard 2009-B, may include visual alerting elements (e.g., multicolored LED indicator lights) and allow for the use of external devices (e.g., pillow vibrators, bed shakers, strobe lights, and loud sirens, which attach via an accessory port) to alert those who are deaf or hearing impaired. == Global weather radio services ==

Both private and commercial seagoing vessels need accurate weather reports, in order to avoid storms that might damage or capsize the vessel, or make paying passengers uncomfortable. One such service is Navtex, which is a low-frequency facsimile radio service. ==North American weather radio services==

The National Oceanic and Atmospheric Administration, Environment Canada, the Mexican Seismic Alert System and the Bermuda Weather Service operate their government weather radio stations on the same marine VHF radio band, using FM transmitters, and the same seven frequencies (162.400-162.550 MHz) as NOAA Weather Radio (NWR). Bermuda only uses 162.550 (land) and 162.400 (marine). The "WX#" format is continued from WX8 up to WX12 on some lists and radios to include 163.275 MHz and or one or more of the Canadian continuous marine broadcast (CMB) frequencies 161.650, 161.750, 161.775, 162.000. Unlike WX1-WX7 typically ordered by frequency adoption by NWS, there is no consistent frequency inclusion nor assignment for WX8-WX12. Effective January 1, 2019, channels 2027 (161.950 MHz, 27B) and 2028 (162.000 MHz, 28B) are designated as ASM 1 and ASM 2 respectively for application specific messages (ASM) as described in Recommendation ITU-R M.2092. 163.275 MHz was formerly used by the NWS for coordination during power outages. All stations in the United States, Canada, and Bermuda transmit a 1,050 Hz attention tone immediately before issuing a watch or warning, (In Canada a 1050 Hz Tone is only used for a Severe Thunderstorm Warning, Tornado Warning and the Required Monthly Test) and this is used as both an attention tone and as a way to activate many radios that do not have SAME technology. All U.S. and Canadian stations transmit SAME codes a few seconds before the 1,050 Hz attention tone that allows more advanced receivers to respond only for certain warnings that carry a specific code for the local area. SAME codes are defined for counties, parishes, territories, forecast regions, or marine zones, and are set using preassigned six-digit FIPS county codes (in the U.S.) or Canadian Location Codes (in Canada). The SAME code protocol also includes an end-of-message (EOM) tone which is made up of three short data bursts of the binary 10101011 calibration then "NNNN", which some radios will use to mute the speaker after the alert broadcast has been completed. United States NOAA Weather Radio (NWR; also known as NOAA Weather Radio All Hazards) is an automated 24-hour network of more than 1,000 radio stations in the United States that broadcast weather information directly from a nearby National Weather Service office. A complete broadcast cycle is about 3 to 8 minutes long and consists of weather forecasts and local observations. Normal broadcast cycles are interrupted when severe weather advisories, warnings, or watches are issued. NOAA Weather Radio occasionally broadcasts other non-weather related events such as national security statements, natural disaster information, environmental and public safety statements (such as an Amber alert) sourced from the Federal Communications Commission's (FCC) Emergency Alert System. Canada In Canada, Weatheradio Canada transmitted in both official languages (English and French) from 234 sites across Canada. The Canadian broadcast cycle featured the forecast for the forecast region where the transmitters were located, as well as any neighbouring forecast regions there may be. It also included the current conditions for local cities, towns, airports or military bases and the air quality forecast is the last part of the cycle before it switched to the other language to repeat the cycle in either English or French. Weatheradio Canada was permanently discontinued on March 16, 2026. Caribbean/Atlantic Bermuda Radio (call-sign ZBR) is a weather radio station in Bermuda working under the Government of Bermuda. Bermuda has only one station dedicated purely for weather, on 162.55 MHz from Hamilton, now operated by the Bermuda Weather Service with tropical weather forecasts from NOAA. It has a second station, however, for marine conditions and forecasts, ZBR (operated by the Bermuda Maritime Operations Centre), at 162.4 MHz. Mexico Mexico has since launched its own weather radio system, SARMEX (Sistema De Alerta De Riesgos Mexicano, or Mexican Hazard Warning System) for coverage of its cities, which also implements the Mexican Seismic Warning System. Some Mexican alert radios also support activation by a two-tone alert for another type of risk warning. ==European weather radio services==

Germany In Germany, the Deutscher Wetterdienst broadcasts marine weather reports and weather warnings via longwave and shortwave transmissions. ==Commercial weather radio services==

The weather radio band is part of the marine VHF radio band reserved for governmental services. However, most standard AM and FM broadcast radio stations provide some sort of private weather forecasting, either through relaying public-domain National Weather Service forecasts, partnering with a meteorologist from a local television station (or using a meteorologist hired by the station, common when a radio station is a sister station of their TV counterpart or has a news and forecast-sharing agreement), affiliating with a commercial weather service company, or (in the most brazen cases) copying a commercial service's public forecasts without payment or permission. In Canada, the weather information issued by Environment Canada are protected under crown copyright but it is possible to obtain a license to redistribute their weather information Accuweather (through United Stations) and The Weather Channel (through Westwood One's NBC Radio Network) both operate large national weather radio networks through standard AM and FM stations. Brookstone licensed Accuweather's data service for their popular 5 Day Wireless Weather Watcher Cast Forecaster. Microsoft's MSN Direct was a popular data service that included weather forecasting sent over US FM radio signals from 2004 to 2012. It was used by Microsoft Spot watches and Oregon Scientific clocks. == See also ==
