FEMA risk ratings for each hazard

Ratings and expected losses from the FEMA National Risk Index. Each rating compares this county with all US counties for that hazard, from Very Low to Very High. They are planning estimates, not predictions, and they do not describe any single property.

FEMA's National Risk Index (version 1.20, December 2025) gives Putnam County a Risk Index score of 39.8 out of 100[5]. FEMA estimates Expected Annual Loss from all 18 natural hazards at $20.3 million a year[1]. This is a FEMA estimate of average yearly loss, not money anyone paid. FEMA's expected loss values put inland flooding first at $13.6 million a year, then hurricane at $1.3 million and strong wind at $1.1 million[7]. FEMA rates social vulnerability as Very Low[8] and community resilience as Very High[9]. FEMA says its index does not predict the damage a community will have in the next year[10].

FEMA's National Risk Index compares each county with all other US counties. Ratings are relative (Very Low to Very High), not a measure of safety. Never call a place safe, unsafe, good or bad to live in. Risk Index and Expected Annual Loss values are FEMA estimates for planning. They do not predict next year's losses and do not apply to a single property. Flood zones are set by FEMA flood maps for specific properties. County ratings and flood insurance counts do not tell anyone whether an address is in a flood zone. Disaster declaration, NFIP and tornado counts are records of the past for this county only. Do not compare with other counties unless a fact does.
