AtlasCast
The storm,
address by address.
Ten storm types. Ten days out. Four times a day.
I · The idea
Which addresses could a storm reach next?
AtlasCast is a storm forecast that works address by address. It looks days ahead, and it names the places a storm could touch, not just the region it is heading for.
II · Ten storm types
Ten storms. One forecast.

Tornado
Rotating storms

Hail
Ice stones from the sky

Wind
Damaging gusts

Flash flood
Water that rises fast

Heavy rain
Intense downpours

Winter
Snow and blizzards

Ice
Freezing rain

Coastal surge
Sea water inland

Hurricane
Tropical cyclones

Wildfire
Fire danger
III · Ten days out
Graded A to F.
Every county receives a grade for each forecast window, from the next 24 hours out to ten days. A glance tells you where to look.
IV · Address by address
A list, not a map shading.
Inside each forecast footprint, AtlasCast lists the individual addresses: where they are, which storm type could reach them, and in which window. You can read it on the live map, or take it as data.

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, up to 10 days out, refreshed four times a day. Built so decision-makers see the threat with time to act.

Further detail · 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 and citable 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.
Further detail · 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.

Further detail · How it works
Conditions in. A per-address forecast out.
Four times a day, AtlasCast turns the latest conditions into a forecast for every address in the country.
01
Ingest the feeds
Fresh conditions arrive several times a day, from long-range outlooks to live radar.
02
Read the storm
The storm-environment signals for every point on the grid are derived and scored for each of the ten perils.
03
Trace the path
Each storm is projected across the forecast hours with a confidence cone that widens the further out it looks.
04
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.
Further detail · Why it's different
Not a radar app. A forecast, per address.
01
Per address
Every one of 282.9M U.S. addresses, not a county, not a ZIP, not a radar tile.
02
Forward-looking
A forecast of what's coming, 24 hours to 10 days out, not a static grade of what a property is.
03
Lead time
The threat is flagged days ahead, so crews, carriers and agencies can act before it lands.
04
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.
Further detail · 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.
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.
