The verdict
Harrison County has a nationally busy FEMA history: 24 declarations, more than 66% of counties in this registry. But the state comparison tempers that reading: the total is 1% below the West Virginia county mean. FEMA's separate National Risk Index places the county in the riskiest 26%; that score models loss and vulnerability rather than counting declarations.

Harrison County's FEMA Risk Index score
What does Harrison County's hazard record show?
Reading the federal records together
FEMA's NFIP table contains a substantial paid-claim history for this county: 774 claims and $5.6M in payments. PlainHazard labels 500 or more claims a heavy registry record; that is a reporting bucket, not an official FEMA risk grade. The average paid claim was $7.3K. NFIP totals exclude uninsured flood losses and do not measure how many properties currently carry a policy.
Start with the state benchmark: a West Virginia county averages 24.2 federal declaration records, while Harrison County has 24. The gap is 1% below that mean. Fewer entries indicate a quieter history of recorded federal actions, not immunity from a hazard and not a prediction about what happens next.
FEMA National Risk Index
This county carries a high composite score on FEMA's National Risk Index, 73.6/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $28.2M in annualized losses), and a Relatively Moderate social-vulnerability profile combined with Very High community resilience shapes how much of that raw exposure becomes realized harm. Among the 18 modeled hazards, Riverine Flooding carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 2.8 times per year here, based on 78 historical events on record.

How often does each hazard strike Harrison County?
FEMA's National Risk Index models a historical event count and an annualized frequency for each hazard type. Most hazards are expressed as modeled occurrences per year; FEMA expresses drought and heat-wave frequency as event-days per year. These modeled frequencies are not forecasts.
| Hazard | NRI Risk Rating | Recurrence |
|---|---|---|
| Riverine Flooding | Relatively Moderate | an average of 2.8 times per year |
| Landslide | Relatively Low | an average of 1.1 times per year |
| Hail | Relatively Moderate | an average of 2 times per year |
| Lightning | Relatively Moderate | an average of 46 times per year |
| Hurricane | Relatively Low | roughly once every 52 years |
| Winter Weather | Relatively Low | an average of 9.5 times per year |
| Earthquake | Very Low | roughly once every 1,603 years |
| Ice Storm | Relatively Low | roughly once every 7 years |
| Strong Wind | Relatively Low | an average of 1.1 times per year |
| Heat Wave | Relatively Low | 1.9 modeled event-days per year |
| Drought | Relatively Low | 2.9 modeled event-days per year |
| Tornado | Relatively Low | roughly once every 18 years |
| Wildfire | Very Low | roughly once every 16,184 years |
| Cold Wave | Very Low | an average of 1.6 times per year |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Harrison County's record, 42% of its declarations. In FEMA's vocabulary this covers convective weather: thunderstorm straight-line winds, large hail, and the multi-day outbreaks that often carry embedded tornadoes. Activity is heaviest in spring and summer, though the season varies by region.
These events behave differently from a hurricane on paper. Damage tends to be distributed along a storm track rather than concentrated on a coastline, and a declaration typically follows an outbreak that crossed several counties over a few days, not a single point of impact. Because the qualifying threshold is the cost of uninsured public and individual losses rather than storm intensity, two similar storms can produce a declaration in one year and none in another.
Declaration counts describe past federal action. They are a record of what was declared, not a forecast of future hazard probability.

The model's sharpest exposure here: Riverine Flooding
Riverine Flooding is the model's measure of a watershed draining more water than its channel can carry. Unlike flash flooding it usually builds over days and is forecast in advance, which makes it the hazard where warning time most reliably converts into reduced harm.
Worth noting for Harrison County: the model and the federal record do NOT point at the same hazard. Riverine Flooding carries the highest modeled rating (Relatively Moderate), while the county's declaration history is led by Severe Storm. That is not a contradiction, the two measure genuinely different things. Declarations record federal ACTION, which requires damage costly enough to exceed state and local capacity; the Risk Index models EXPECTED annual loss across all 18 hazards whether or not any declaration ever followed. A hazard can be the county's largest modeled exposure and never once have driven a declaration.
National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.
