Platform
From weather data
to your address list.
How AtlasCast works, in plain steps.
I · How it works
Four quiet steps, start to finish.
Data in
The latest conditions flow in several times a day, so every forecast stays current.
Addresses, listed
AtlasCast matches the forecast to each address at its location: sharpest in days one to three, broader in days four to ten.
Forecast out
The result is a list of the addresses a storm could reach, with an A to F grade rolled up for each county, for windows from 24 hours to ten days. It is rebuilt four times a day, at 03, 09, 15 and 21 UTC.
Delivery
Read it on the live map, pull it through the Atlas United API at five cents per address with no contracts, or connect through MCP at mcp.atlasunited.io/mcp. AI agents can pay per call and fetch it themselves.
II · Honest limits
What it cannot do.
- A forecast shows what could happen, not what will. Confidence falls the further out you look.
- Weather models work on grids, so addresses in the same cell share that cell’s forecast.
- Past storms are described as reported and radar-detected, never as proven at a given address.
- It is a forecast of weather, not a loss estimate for an insurer.
- Atlas United is not affiliated with NOAA or the National Weather Service.
