For a U.S. phone setup, use three layers: keep Wireless Emergency Alerts enabled for critical government alerts, use the USGS National Water Dashboard to check nearby water and weather observations, and bookmark National Weather Service radar and forecast pages. Add a USGS WaterAlert subscription if a nearby station measures something useful. Gauge messages and maps add context; they are not a guarantee of timely warning.
Set up a reliable phone-based monitoring system
1. Keep Wireless Emergency Alerts enabled
Wireless Emergency Alerts (WEA) are government-authorized alerts delivered to compatible phones through participating wireless carriers. They do not require an app or subscription. WEA is intended for specially designated critical alerts, not every weather watch, advisory, or local rainfall reading, so treat it as an emergency layer rather than your sole source of weather information. Learn about Wireless Emergency Alerts from the National Weather Service.
2. Find nearby gauges in the USGS National Water Dashboard
Open the USGS National Water Dashboard on your phone and look for active monitoring sites near your home, workplace, or usual routes. The map combines USGS water observations with NWS radar, watches and warnings, and rainfall information. A USGS announcement dated October 30, 2020, described data from more than 13,500 observation stations; that is a figure from that announcement, not a current live station count. Read the USGS announcement.
Check what a nearby site actually measures. A stream gauge is useful for seeing water conditions at that location, but it is not a direct measure of rainfall everywhere in your area. Station coverage and available sensors vary.

3. Subscribe to USGS WaterAlert when a station has a useful sensor
From a suitable station, choose an available measurement and set a threshold for an email or phone notification through USGS WaterAlert. The choices depend on the station. For rainfall, consider what the accumulated precipitation value represents and whether the station’s location and threshold are relevant to your situation. You may need to adjust the threshold after seeing how local conditions and readings correspond.
WaterAlert depends on incoming site data. USGS says data often arrive hourly and may arrive more frequently during floods; notifications may not reach you in time during an emergency. Use them as additional context, not as an emergency warning service. See WaterAlert information and subscriptions.

Know what each source can—and cannot—tell you
| Source | Best use | What to keep in mind |
|---|---|---|
| Wireless Emergency Alerts | Critical government-authorized alerts on compatible phones through participating carriers. | No app or subscription is needed, but WEA is not a feed of every watch, advisory, or rainfall observation. NWS WEA information. |
| USGS National Water Dashboard | Viewing water observations alongside NWS radar, watches, warnings, and rainfall information. | Nearby sites and their sensors differ; a map or gauge does not guarantee safety. USGS Dashboard. |
| USGS WaterAlert | Notifications when a selected measurement at a specific monitoring site crosses a chosen threshold. | It depends on station availability and incoming data; notification timing may not be adequate in an emergency. USGS WaterAlert. |
| NWS Radar | Checking radar, current weather, official alerts, and forecasts for a location. | Bookmark the location view for quick access; continue to check for changing conditions. NWS Radar. |
| FEMA app | Receiving NWS/IPAWS alerts for saved locations, including places away from your current location. | The FEMA listing describes up to five locations at ZIP-code precision; verify current app features and settings. FEMA mobile products. |
Respond to a flood warning, not just the rainfall total
A warning means hazardous impacts are expected or occurring. The National Weather Service says a Flash Flood Warning means dangerous flash flooding is expected: move to higher ground, and never walk or drive through floodwater. NWS flood safety guidance.
