The verdict
Accomack County has a nationally busy FEMA history: 20 declarations, more than 46% of counties in this registry. But the state comparison tempers that reading: the total is 2% below the Virginia county mean. FEMA's separate National Risk Index places the county in the riskiest 19%; that score models loss and vulnerability rather than counting declarations.

Accomack County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Accomack County is led by Hurricane (about $13.2M Expected Annual Loss, Historical Loss Ratio Relatively High), while Coastal Flooding carries the highest National Risk Index rating (Very High). EAL and risk score use different inputs; they need not agree.

What does Accomack County's hazard record show?
Reading the federal records together
FEMA's NFIP table contains a substantial paid-claim history for this county: 1,113 claims and $12.6M 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 $11.3K. NFIP totals exclude uninsured flood losses and do not measure how many properties currently carry a policy.
Start with the state benchmark: a Virginia county averages 20.4 federal declaration records, while Accomack County has 20. The gap is 2% 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 sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 81.0/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Low (roughly $31.2M in annualized losses). Social vulnerability reads Very High and community resilience Relatively High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Coastal Flooding stands out as the sharpest exposure here, rated Very High. FEMA's modeled frequency puts that hazard at an average of 3.7 times per year here.

How often does each hazard strike Accomack 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 |
|---|---|---|
| Coastal Flooding | Very High | an average of 3.7 times per year |
| Hurricane | Relatively High | roughly once every 4 years |
| Wildfire | Relatively Low | roughly once every 885 years |
| Drought | Relatively Low | 2 modeled event-days per year |
| Cold Wave | Relatively Low | roughly once every 1 years |
| Heat Wave | Relatively Low | 5 modeled event-days per year |
| Earthquake | Very Low | roughly once every 1,067 years |
| Riverine Flooding | Relatively Low | roughly once every 2 years |
| Ice Storm | Relatively Low | roughly once every 4 years |
| Strong Wind | Relatively Low | roughly once every 2 years |
| Winter Weather | Relatively Low | an average of 5.1 times per year |
| Hail | Very Low | roughly once every 1 years |
| Lightning | Very Low | an average of 34 times per year |

What Hurricane declarations mean here
Hurricane is the most frequent declaration type on Accomack County's federal record, 50% of its declarations. Atlantic tropical systems run on a defined season, 1 June to 30 November, with most activity concentrated between August and October; Pacific and territorial basins run on their own calendars. A single named storm routinely produces one declaration number covering a long corridor of counties at once, well inland as well as on the coast, which is why an affected county's count can jump by several in one year without several separate events having occurred.
One practical distinction matters when reading these records: a tropical declaration usually bundles wind, storm surge and inland rainfall flooding under a single incident, but the insurance behind them is split. Wind damage falls to property insurers, while flood and surge damage is covered only under a separate National Flood Insurance Program policy. That is why a county can show heavy declaration activity and a comparatively small NFIP claims record, or the reverse.
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: Coastal Flooding
Coastal Flooding is modeled separately from riverine flooding because its driver is different: surge, tide and wave action rather than a watershed draining. It is also the hazard whose baseline is moving, since the same storm rides on a higher starting sea level than it used to.
For Accomack County the two measures on this page point the same way: Coastal Flooding is the county's highest-rated modeled hazard (Very High), and Hurricane declarations also lead its federal record. Where the model and the declaration history agree, the reading is comparatively straightforward, the hazard is both expected and repeatedly realised.
National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.
