Weather and public-safety alerts are designed to get attention quickly. Read the message, note the issuing agency and area, and follow the action it tells you to take. Do not rely on a generic tone description to decide whether an alert is urgent.
Two official alert systems to know
NOAA Weather Radio All Hazards broadcasts National Weather Service warnings, watches, forecasts, and other hazard information around the clock. It requires a compatible radio or scanner; the National Weather Service lists the seven broadcast frequencies and coverage information.
Wireless Emergency Alerts (WEAs) are short messages from authorized alerting authorities delivered to compatible phones in a targeted area. The FEMA WEA guide explains that no app or subscription is required. The message can include the hazard, timing, recommended action, and issuing agency.
Use the right setup guide
- NOAA Weather Radio alert setup explains receiver setup and SAME location codes. Use current NWS or local emergency-management information to confirm your county code and transmitter.
- Emergency alert sounds on your phone explains what a WEA is and where phone notification settings may affect optional alerts. The exact menu labels vary by phone and operating system.
When an alert arrives
Follow the message first, then check trusted local authorities, the National Weather Service, or local news for updates. Keep a backup power source for radios and phones when severe weather is possible. If an alert repeats unexpectedly, review the device or carrier guidance after the immediate situation; do not disable alerts broadly just because one tone was inconvenient.
