About

US Disaster Alert watches official hazard feeds for the places you choose and tells you when something crosses the threshold you set. It is run by EarlyWarningText, LLC.

Why it exists

Wireless Emergency Alerts — the ones your phone makes on its own — are free, automatic and good at one job: warning the phone you are carrying, about the most extreme events, where you happen to be standing. They cannot tell you about your mother's house two states away, they fire only at the top of the severity scale, and once you dismiss one it is gone.

This service covers the gap. You name the places that matter, you set how severe an event has to be before you want to hear about it, and everything we send names its source, its area, its severity and when it expires.

Where the information comes from

Every alert originates with a public agency — the National Weather Service, the USGS Earthquake Hazards Program, the NOAA Space Weather Prediction Center — and we pass it on with the issuing agency named. We do not write warnings of our own, and we do not decide what counts as an emergency. What we add is matching: which alerts concern the places you have saved, at the severity you asked for.

How quickly

Published, not promised. The service status page shows real delivery times from the last 24 hours, split into the part we are responsible for and the part we are waiting on an agency for, because presenting their delay as ours would be dishonest in both directions. It also shows whether each source is answering and whether our own workers are alive.

What this is not

US Disaster Alert relays public information. It is not an official emergency service, not a substitute for emergency management instructions, and not something to rely on as your only warning. Keep your phone's built-in emergency alerts switched on. In an emergency, call 911 and follow the direction of local authorities.
