Swift Warning
Live sources are labeled. Planned sources are labeled too.

Coverage and sources

Honest about what is on the wire today.

Wildfire dispatch, national and California incident feeds, satellite heat, air quality, and NWS fire weather are live. Earthquakes, all-hazard weather alerts, hurricanes, flood gauges, and live radar are the next public feeds.

Hazard list Radar plan

Coverage always varies by source, jurisdiction, network, and device. A listed planned source is not ingested yet.

Live now

Sources already on the wire.

These feeds power today's wildfire map, air-quality context, and fire-weather watches.

WildCAD

Public wildfire dispatch activity from 43 monitored centers across the Western United States.

Live now. Checked every 45 seconds by default. Visit source

NIFC

National interagency wildfire information and incident context.

Live now. Processed on a five-minute service cycle. Visit source

CAL FIRE

California incident information published by CAL FIRE.

Live now. Processed on a five-minute service cycle. Visit source

NASA FIRMS

Satellite-detected thermal activity from NASA's fire information system.

Live now. Processed on a five-minute service cycle. Visit source

National Weather Service

Fire Weather Watches and Red Flag Warnings today. The same alert API is the path to tornado, flood, hurricane, heat, and winter alerts.

Live now for fire weather. Broader alerts are next. Visit source

Building next

Public feeds for the rest of the map.

These are the first sources we intend to ingest. None of them should be described as live until a production poller and a user-visible layer exist.

USGS earthquakes

Global real-time earthquake GeoJSON, including magnitude, depth, tsunami flag, and PAGER impact when present.

Building next. Hour feed updates about every minute. Visit source

NWS all-hazard alerts

United States watches and warnings for tornado, flood, hurricane, heat, winter storm, tsunami, dust storm, and more from the same CAP API we already use for fire weather.

Building next. Current poller is fire-weather only. Visit source

National Hurricane Center

Active tropical cyclones, forecast track, cone, and watches or warnings for the Atlantic and eastern and central Pacific.

Building next. Live JSON and GIS products already exist. Visit source

USGS water gauges

Streamflow and gage-height readings near saved places, used with flood warnings rather than instead of them.

Building next. Typical gauge step is about 15 minutes. Visit source

Storm Prediction Center

Convective outlooks and storm reports that add tornado and severe-storm context around official warnings.

Building next. Visit source

Live weather radar

A worldwide radar mosaic plus a higher-detail United States layer. See the radar page for coverage limits.

Building next. Typical mosaic refresh is several minutes. Visit source

DOE / EAGLE-I outages

National county-level power outage counts from the Department of Energy feed published through FEMA. Covers most US customers, not every utility or every circuit.

Building next. About hourly. Visit source

Coverage questions

What is live, and what is not.

Short answers so the product direction is not mistaken for a live feed.

Does Swift Warning already track earthquakes?

Not yet. Earthquake pins are on the build list and will use the USGS real-time GeoJSON feed first. Until that poller is in production, do not treat Swift Warning as an earthquake app.

Does Swift Warning already show live radar?

Not yet. The radar page explains the worldwide mosaic and United States high-resolution plan. Radar tiles will be a map overlay, not a replacement for a tornado or flood warning.

What fire areas are covered today?

Swift Warning monitors 43 WildCAD dispatch centers across Western states and adds NIFC, CAL FIRE, and NASA FIRMS context. Coverage is not complete in every county or jurisdiction.

Will coverage be worldwide?

Earthquakes and radar mosaics are global by nature, with gaps. Weather warnings, flood gauges, and hurricane cones start with United States public feeds, then add other national agencies.

Keep official alerts on

No source list replaces Wireless Emergency Alerts.

Keep official phone alerts enabled. Follow local authorities. Call 911 in an emergency.
