Alabama Severe Weather Hazard Profile
Hazard Data · Model Version 2.5
Overview
Alabama is part of Dixie Alley, where nocturnal and rain-wrapped tornadoes pose elevated risk compared to traditional Tornado Alley. NOAA Storm Events data shows Alabama has one of the highest per-capita tornado fatality rates in the US. The Southeast tornado maximum, driven by Gulf moisture and strong wind shear, peaks in March-April and November.

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.
