Further detail · Storm data

The five products, and what they do not claim.

AtlasCast matches storm forecasts to addresses for ten perils. Each listed address carries a risk label; the A to F grade is the county’s. Storm history and the recent-storm lists are records of reported and radar-detected events matched to addresses. Forecasts refresh about four times a day.

What the storm data does not claim.

Could happen, not will

Forecasts describe what could happen, not what will happen. They are not a prediction of damage to any structure.

A record, not a damage assessment

History and the recent-storm lists are a record of reported and radar-detected events. They do not confirm a claim, a loss or damage to a structure.

Area signal, not rooftop certainty

Nearby addresses can share a signal. The county grade is a whole-county label, not a property score.

V · Address Risk Profile

More on each address.

Licensed partners can add an Address Risk Profile to the addresses they pull: long-term peril grades and storm-loss history, on the same API and key.
