Madison County, AL has the highest ice storm risk in Alabama, with a FEMA National Risk Index score of 90.6 out of 100 (rated "Relatively High").
What causes ice storm risk in Alabama?
Ice storm risk covers damaging freezing rain and sleet accumulation, which collapses power lines, trees, and structures. The highest-risk counties cluster in a band from eastern Texas and Arkansas through the Carolinas and New England, where warm Gulf moisture overruns cold arctic air most frequently. Ice storms cause catastrophic and long-lasting power outages. Ice storm and sleet events are reported at forecast-zone level in NOAA Storm Events and are not included in county-level counts.
