Alerts that wake you: NOAA Weather Radio, phone alerts and local apps
Set up more than one way to receive an overnight warning. Start with official alerts, then add local coverage.

1. Set up a NOAA Weather Radio
Choose an alert-capable receiver with battery backup. A radio that only plays weather audio may not automatically sound an alarm. SAME (Specific Area Message Encoding) lets compatible receivers filter alerts for selected counties or areas.
Use the NWS transmitter and county information to find a station covering your home. Follow your receiver’s manual to enter the correct SAME code, enable warning alarms and check reception where you sleep. Keep fresh backup batteries installed.
Confirm reception and use the manufacturer’s test procedure. Check the local NWS routine test schedule; a quiet radio does not prove it works. If sound is not an effective alert for you, investigate compatible strobes or bed shakers and test the full setup.
2. Check Wireless Emergency Alerts on your phone
WEA is a government alert service delivered through participating mobile networks to compatible phones. It requires neither a weather-app subscription nor a signup. A tornado warning phone alert can reach you where you are, rather than only at a saved home address.
Search your phone settings for “Emergency alerts” or “Government alerts.” Confirm emergency weather alerts are enabled. Menu names and available controls vary by phone, carrier and software; use the device maker’s instructions. Check sound and accessibility settings before bedtime.
Keep the phone charged and within reach. Coverage, device compatibility and settings affect delivery. Do not assume every weather warning triggers WEA, or that one phone will always wake every sleeper.
3. Add local apps and an overnight plan
Use your county or city emergency-management website to find its official alert signup. A trusted local weather app can add context; confirm its location permissions, notification settings, selected hazards and any available test function. Recheck saved locations when traveling.
A watch means prepare for possible hazardous weather. A warning means act on the hazard described. Decide where everyone will go, who needs assistance, and how pets will be moved before going to bed. Do not wait for a livestream to confirm a warning.
This site’s free browser alerts work only while the page is open and able to run. They are supplemental, not WEA, NOAA Weather Radio, or a guaranteed wake-up service. Phone sleep modes, suspended tabs, network loss and power loss can interrupt browser alerts.
