Hanover County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Hanover County is led by Riverine Flooding (about $15.4M Expected Annual Loss, Historical Loss Ratio Relatively High), while Drought carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Hanover County's hazard record show?
FEMA National Risk Index
This county carries a high composite score on FEMA's National Risk Index, 53.5/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $28.5M in annualized losses), and a Very Low social-vulnerability profile combined with Very High community resilience shapes how much of that raw exposure becomes realized harm. Of the 18 hazards FEMA models, Drought stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at 4.8 modeled event-days per year here, based on 147 historical events on record.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 39 claims and $625.1K paid in total. PlainHazard calls 1-49 claims a light registry record, a label for this dataset rather than a finding that flood exposure is low. A short claims history can also reflect insurance take-up, the period covered, or losses that were never insured.
The declaration register points in the busier direction. Hanover County's 22 federal records stand 8% above the Virginia county mean of 20.4. That comparison describes how often federal action was recorded, including any Major Disaster, Emergency, and Fire Management entries shown on this page; it does not convert the count into future probability.

How often does each hazard strike Hanover 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 |
|---|---|---|
| Drought | Relatively High | 4.8 modeled event-days per year |
| Earthquake | Relatively Low | roughly once every 361 years |
| Hurricane | Relatively Low | roughly once every 10 years |
| Riverine Flooding | Relatively Low | roughly once every 1 years |
| Ice Storm | Relatively Moderate | an average of 1.2 times per year |
| Heat Wave | Relatively Low | 4.7 modeled event-days per year |
| Lightning | Relatively Moderate | an average of 42 times per year |
| Tornado | Relatively Low | roughly once every 4 years |
| Strong Wind | Relatively Low | an average of 2.3 times per year |
| Hail | Relatively Low | an average of 2.4 times per year |
| Landslide | Very Low | roughly once every 3 years |
| Wildfire | Very Low | roughly once every 9,146 years |
| Winter Weather | Relatively Low | an average of 6 times per year |
| Coastal Flooding | Very Low | an average of 3.7 times per year |
| Avalanche | Very Low | roughly once every 100 years |

What Hurricane declarations mean here
Hurricane is the most frequent declaration type on Hanover County's federal record, 32% 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: Drought
Drought is the slowest of the modeled hazards and the least visible: it does its damage to agriculture, water supply and soil over seasons rather than hours, so it rarely produces the kind of single-day damage that drives a disaster declaration. FEMA scores it in event-days per year rather than discrete events for exactly that reason.
Worth noting for Hanover County: the model and the federal record do NOT point at the same hazard. Drought carries the highest modeled rating (Relatively High), while the county's declaration history is led by Hurricane. 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.
