When severe weather strikes, access to reliable information becomes critically important. Hurricanes, tornadoes, blizzards, floods, wildfires, and major storms can quickly overwhelm cellular networks, disrupt internet access, and create rapidly changing conditions where timely alerts matter enormously.
Do not be caught out!
This is where NOAA Weather Radio continues to play a vital role.
NOAA Weather Radio is a nationwide network of radio transmitters operated by the National Weather Service that continuously broadcasts:
- Severe Weather Alerts
- Tornado Warnings
- Hurricane Updates
- Flood Warnings
- Winter Storm Advisories
- Marine Forecasts
- Emergency Alerts
- Civil Emergency Information
One of the reasons NOAA Weather Radio remains so valuable is that it operates independently of many modern communication systems. A simple weather radio, scanner, SDR receiver, or compatible handheld radio can continue receiving emergency broadcasts even during major infrastructure disruptions and widespread power outages.
For radio hobbyists, emergency preparedness enthusiasts, storm spotters, and scanner listeners, NOAA weather frequencies are often some of the most important channels to monitor during severe weather season. In many situations, NOAA alerts provide faster and more direct warnings than television broadcasts, websites, or social media feeds.
Over the years, I’ve found that many people underestimate how useful a dedicated weather radio or scanner can be until severe weather actually arrives. During major storms, NOAA broadcasts often become one of the most reliable sources of continuous real-time information available.
In this guide, I’ll cover:
- NOAA Weather Radio frequencies
- how the NOAA weather alert system works
- what equipment can receive NOAA broadcasts
- SAME alert technology
- scanner and SDR monitoring options
- and how to build a reliable emergency weather monitoring setup
Whether your goal is emergency preparedness, storm monitoring, scanner listening, or building a more resilient source of emergency information, NOAA Weather Radio remains one of the most useful radio services still operating today.
The Seven (and Only Seven) NOAA Weather Radio Frequencies
All NWR stations in the United States, Canada, and U.S. territories operate on exactly these channels:
Channel | Frequency | Historical Name | Notes |
|---|---|---|---|
1 | 162.400 MHz | WX1 | Most common nationwide |
2 | 162.425 MHz | WX2 | Very common |
3 | 162.450 MHz | WX3 | Common in Midwest & South |
4 | 162.475 MHz | WX4 | Common in Northeast & Great Lakes |
5 | 162.500 MHz | WX5 | Common in Plains & Mountain states |
6 | 162.525 MHz | WX6 | Common in Pacific Northwest & Rockies |
7 | 162.550 MHz | WX7 | Most common in the Southeast, Gulf Coast, and Florida |
What Frequency Is NOAA Weather Radio On?
NOAA Weather Radio operates on seven nationwide VHF frequencies between 162.400 MHz and 162.550 MHz. Most scanners, weather radios, SDR receivers, and many ham radios can monitor these channels. That’s it. There are no WX8–WX12 channels in normal use in the U.S.
How to Find Your Local Transmitter and Frequency
Go to: www.weather.gov/nwr/station_listing
or
https://www.weather.gov/skywarn/nwr (interactive map with coverage footprints)
Enter your county → you’ll instantly see:
- Exact frequency
- Callsign (e.g., KHB-36, WXJ-75)
- Transmitter location and power
- Six-digit SAME/FIPS code(s) for your county
Understanding SAME (Specific Area Message Encoding)
Since 1998, every alert broadcast contains a digital header with one or more SAME codes.
Your radio stays silent until it hears a code that matches what you programmed.
Common Event Codes You’ll Hear (first three letters):
- TOR = Tornado Warning
- SVR = Severe Thunderstorm Warning
- FFW = Flash Flood Warning
- EWW = Extreme Wind Warning
- SMW = Special Marine Warning
- BZW = Blizzard Warning
- TSU = Tsunami Warning
- EVA = Evacuation Immediate (used in chemical spills, dam breaks, wildfires)
- RWT = Required Weekly Test (usually Wednesday ~11 a.m. local)
How to Program Your Scanner or Weather Radio for SAME Alerts (Step-by-Step)
Dedicated NOAA Weather Radios (Midland WR-120, WR-400, etc.)
- Power on → MENU → enter your six-digit SAME code (one code per county; add up to 25 on most models).
- Set to “ANY” code if you want every single alert the transmitter can reach (useful for travelers).
- Choose alert type: Voice + 1050 Hz tone (default) or Tone-only for nighttime.
- Test: MENU → “Test” or wait for the Wednesday RWT.

Pro Tips That Save Lives
- Program at least two adjacent counties — warnings are often issued for the county next door first.
- Use an external antenna (even a $12 mag-mount on a filing cabinet) if you live in a basement or metal building.
- Enable “SAME ANY” when traveling or during widespread severe weather outbreaks.
- Keep fresh batteries or a small power bank — NWR is useless if your radio dies when the grid does.
When tornado sirens are silent because the power is out, NOAA Weather Radio with SAME is still screaming the warning directly to your nightstand.
Program it once, sleep better forever.
Best Scanners and Radios for NOAA Weather Radio
My History with NOAA
In the late 1970’s, I would venture to a local hilltop in my town so that I might pick up the Buffalo NOAA broadcast. I was in Burlington, Ontario, and I could pickup up Buffalo, NY. Canada did not have a service like this for a few more years. They used real human voice segments in those days. I wish I had recorded it. It would be valuable evidence. At the time, I was not a licensed ham, but I was a dedicated SWL.
UPDATE:
The situation regarding weather radio frequencies is currently a tale of two different directions, depending on which side of the border you are on.
Canada: Discontinuation of Service
As of March 16, 2026, Environment and Climate Change Canada has permanently discontinued the Weatheradio Canada service.
- Status: The Seven VHF frequencies (162.400, 162.425, 162.450, 162.475, 162.500, 162.525, and 162.550 MHz) are no longer broadcasting weather data in Canada.
- Replacement: The government is directing citizens to use the WeatherCAN app or the official website for alerts.
- Impact: This has been a significant point of discussion among radio hobbyists, as it removes a critical “off-grid” safety net for those in remote areas without cellular coverage.
And today, it has been announced that CHU Canada, their official time signal is being discontinued.
United States: Modernization and Expansion
In contrast, the U.S. is moving to strengthen its network. The NOAA Weather Radio Modernization Act (H.R. 7813) recently passed through the House Committee on Science, Space, and Technology in March 2026.
- Frequencies: There are no new frequencies being added to the standard seven-channel lineup. The system will continue to operate on the existing VHF band (162.400–162.550 MHz).
- Infrastructure Upgrades: The legislation authorizes $100 million for FY 2026 to:
- Replace aging transmitters and antennas.
- Transition away from unreliable copper-wire transmissions to fiber and IP-based protocols.
- Expand coverage to reach 98–99% of the U.S. population, particularly in rural and “dead zone” areas.
- New Technologies: NOAA is investigating the use of satellite backups and internet-protocol (IP) dissemination to ensure the “Voice of NOAA” stays on the air even if a local forecast office or landline fails.
If you are using a scanner or a programmable radio in the U.S., these remain the active channels:
While the frequencies aren’t changing, the reliability of the transmitters behind them is expected to improve significantly over the next year as the modernization funding kicks in.
