The five products, and what they do not claim.
AtlasCast forecasts come from a separate machine-learning model for each of 10 perils, trained and validated chronologically on held-out reported events and restricted to information available at forecast issue time. Storm history and past storm leads are records of reported and radar-detected events matched to addresses. Forecasts refresh 4 times a day, are timestamped, versioned and reproducible, and paid storms, risk, history and hazard_score responses carry a reference_id.

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 past storm leads are a record of reported and radar-detected events. They do not confirm a claim, a loss or damage to a structure.
Replacement cost, not market value
They exclude land and location premium.
Area signal, not rooftop certainty
Nearby addresses can share a signal. The county grade is a whole-county label, not a property score.

Dolly, PTC, 35kt/40mph (1500 UTC Aug 28)
| Position | 15.0N, 46.9W |
| Max sustained wind | 35kt / 40mph |
| Central pressure | 1008 mb |
| Movement | WNW at 25mph |
| Sea surface temp | 82.0F |
Outlook
Weakened to post tropical as expected. Winds expected to fall below tropical storm strength by Saturday. Main real threat now is heavy rain and flash flooding for the Leewards, Puerto Rico, and Hispaniola, not wind.
Our predicted positions
| +48h | 13.9N, 70.8W |
| +96h | 20.4N, 95.3W |
Caveat: Dolly became an open wave and is no longer tracked. Regeneration odds are low with no consensus location. Our predicted track agrees this is not shaping up as a serious US threat; our 96h point lands near the Mexico coast, not Texas.
