Toggle radar on the map
Turn on a live overlay around your current location or a saved place.
Radar is on the build list. It is not a live map overlay yet.
Live weather radar
A radar layer for storms around the world.
Swift Warning is adding live weather radar to the same map that already watches wildfires. The goal is a worldwide mosaic for rain, storms, and snow, plus a higher-detail United States layer from NOAA radar.
Radar shows where precipitation is detected. It is not a tornado warning, flood warning, or evacuation order.
How the radar layer will work
World mosaic
A composite of national radar networks where they exist.
United States detail
NOAA MRMS or RIDGE2 when you zoom into the States.
Coverage mask
Empty ocean or a silent desert is not the same as no storm.
What you will be able to do
See the storm, then read the warning.
Radar is context for the official alerts Swift Warning will also ingest. A bright blob on the map is not permission to ignore a siren.
Scrub the last hour or two
See whether a cell is moving toward home, a campsite, or the road ahead.
Read the official warning beside it
Tornado, flood, and hurricane alerts will come from National Weather Service and National Hurricane Center products, not from a radar pixel.
Limits we will keep visible
Worldwide does not mean no gaps.
A honest radar product shows where data exists. It does not invent rain over the open ocean or a country with no public radar.
Radar networks have holes
Mountains, oceans, and some countries have little or no ground radar. We will show a coverage mask.
Tiles refresh in minutes
A worldwide mosaic is usually several minutes old. It is not a one-second storm siren.
Satellite fills some gaps
Where radar is missing, satellite precipitation can add context. That is still an estimate.
No push from a pixel alone
Swift Warning will not send a life-safety notification only because a radar tile turned green or red.
How we will build it
Public mosaics first, then US high-res.
The first overlay is a worldwide radar mosaic. The second is United States high-resolution radar from NOAA. Commercial mosaic terms will be confirmed before anything depends on a single vendor.
What to keep in mind
- United States display radar is not available from api.weather.gov. That API is forecasts, alerts, and radar status.
- NOAA MRMS and RIDGE2 are the public US display path.
- A worldwide mosaic still needs attribution and a backup if a vendor changes terms.
Official instructions come first
Until the overlay ships, Swift Warning does not have live radar. This page is the public plan, not a current feature.
More of the map
Radar is one layer. The hazard list is the rest.
Earthquakes, floods, hurricanes, and tornadoes have their own official feeds. Radar sits beside them on the same saved-place map.
