AtlasCast · Live severe-weather forecasting

Severe weather, forecast to the address.

Atlas United grades the risk a property carries. AtlasCast forecasts the storm that's coming for it — 10 storm types, per address, 16 days out, refreshed four times a day. Built entirely on U.S. federal weather models, so decision-makers see the threat with time to act.

What it's used for

Lead time is the product.

AtlasCast turns federal weather models into an address-level warning the teams responsible for people, property, and infrastructure can act on — days before impact.

Emergency management

Pre-position crews and shelters, alert vulnerable facilities — schools, hospitals, nursing homes — by exact address, and buy evacuation lead time before impact.

Insurance & reinsurance

See which addresses on the book face incoming severe weather, warn policyholders to mitigate, and pre-stage catastrophe response, reserves, and claims.

Utilities & energy

Pre-stage line crews ahead of wind and ice, harden the at-risk grid segments, trigger automated hail-stow for solar assets, and cut outage minutes.

Government & public sector

Mitigation planning, hazard mapping, and resilience for Federal, State, and Local agencies — auditable, citable, first-party federal intelligence.

Logistics & aviation

Reroute fleets, protect cargo, and reschedule operations around severe weather with per-corridor lead time instead of last-minute scrambles.

Agriculture

Protect crops and livestock ahead of freeze, hail, and flash flooding — with a forward forecast tied to the specific fields at risk.

Coverage

Ten storm types, every season.

Each U.S. address is classified for the hazard actually forecast to reach it — from spring supercells to winter ice, all from one engine, all from federal data.

How it works

Federal models in. A per-address forecast out.

Four times a day, AtlasCast pulls the government's own weather models and turns them into a forecast for every address in the country.

Ingest the feeds

The same federal weather models the National Weather Service runs — ensemble, high-resolution, and live radar. All first-party government data.

Read the storm

The storm-environment signals for every point on the grid are derived and scored for each of the ten hazard types.

Trace the path

Each storm is projected across the forecast hours with a confidence cone that widens the further out it looks.

Resolve to addresses

The forecast is matched to the 282.9M U.S. addresses under it — who is actually in the path, and how likely.

Why it's different

Not a radar app. A forecast, per address.

Per address

Every one of 282.9M U.S. addresses — not a county, not a ZIP, not a radar tile.

Forward-looking

A 16-day forecast of what's coming — not a static grade of what a property is.

Federal data only

Built entirely on U.S. government weather models. No third-party feeds, no reselling.

All season

Severe, tropical, and winter hazards from a single engine, refreshed around the clock.

A forecast is a probability, not a promise — AtlasCast flags the threat with lead time to act.

Every forecast, explained

A grade tells you what. This tells you why.

Most peril data hands you a color on a map. AtlasCast hands you the physics behind the call — and a signature proving the answer wasn't altered after it left our servers.

The real reason behind every flag

When an address is flagged, AtlasCast shows the actual meteorology that triggered it — CAPE, storm-relative helicity, precipitable water, fire-weather index — not just a grade. Present whenever the qualifying weather is real for that forecast cycle, so the reason is always tied to genuine atmospheric data, never invented after the fact.

Signed, every response

Every AtlasCast forecast carries its own Ed25519 signature and content hash, on its own signing key — separate from the rest of the platform. Recompute the hash and it either matches the response or it doesn't. No ambiguity, no vendor black box.
