FEMA relative scores

Ice Storm Risk Rankings

The highest relative ice storm scores among FEMA county-equivalent areas represented in the city directory.

One FEMA area can contain several covered cities. Each area appears once below, with links to its city pages. The score is a relative comparison measure, not the annual chance of a ice storm.
