Hazard Data · Model Version 2.5
Overview
Colorado's Front Range is part of the US hail corridor, with the Denver-Colorado Springs metro area experiencing some of the highest hail frequencies in the nation. NOAA SPC data and IBHS research show Colorado consistently ranks in the top 5 states for hail-related insured losses. Severe thunderstorm winds and occasional tornadoes occur east of the Continental Divide.

Hazard Scoring Approach
Calchis computes a Calchis Hazard Score (0–10) for severe weather hazard at any US address. The score is composed of weighted sub-components derived from federal data sources and published research. All score components are transparent and returned in API responses.
These are hazard scores — physical intensity likelihood only. They do not include property exposure or vulnerability data. We never call a hazard score a risk score. See the full methodology for scoring details.
