Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Caroline County is led by Hurricane (about $4.8M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Drought carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Caroline County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 77 paid claims, totaling $1.4M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $17.9K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

The declaration register points in the busier direction. Caroline County's 21 federal records stand 7% above the Maryland county mean of 19.6. 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.

FEMA National Risk Index

FEMA's data shows an elevated National Risk Index composite of 45.7/100 for this county (Relatively Low rating). Expected Annual Loss comes in at Very Low (roughly $12.5M in annualized losses). Social vulnerability (Relatively Moderate) and community resilience (Relatively Moderate) both factor into how that raw exposure plays out on the ground. 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 4.2 modeled event-days per year here, based on 154 historical events on record.

How often does each hazard strike Caroline 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 4.2 modeled event-days per year
Hurricane Relatively Moderate roughly once every 8 years
Strong Wind Relatively Moderate an average of 4.1 times per year
Winter Weather Relatively Moderate an average of 7.5 times per year
Wildfire Relatively Low roughly once every 901 years
Heat Wave Relatively Low 5.6 modeled event-days per year
Coastal Flooding Relatively Low an average of 3.7 times per year
Earthquake Very Low roughly once every 808 years
Cold Wave Relatively Low roughly once every 1 years
Lightning Relatively Low an average of 35 times per year

What Snowstorm declarations mean here

Snowstorm is the most frequent declaration type on Caroline County's record, 33% of its declarations. Snow-related declarations work on a narrower basis than most other hazards: they are generally issued to reimburse the cost of snow removal and emergency protective measures, rather than to repair destroyed property.

The qualifying test is unusual too. FEMA assesses snowfall against record levels for the affected area, so the same storm total can qualify in a county where it is historically extreme and not qualify a few hundred miles north where it is an ordinary winter. A low snowstorm declaration count is therefore not evidence of mild winters.

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 Caroline 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 Snowstorm. 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.

Data-matched county comparisons

Caroline County's closest FEMA peer: Benton County, IN

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Caroline County. Record similarity, not a safety rating.

How these peers are chosen

Cohort: Published U.S. county equivalents outside the source state or territory. Each metric keeps six ETL candidates; three unique destinations are shown after de-duplicating across axes. Declaration-volume ranking combines count and Major-disaster share and prefers a different leading incident type; Major-share ranks the Major fraction adjusted for volume; NRI ranks the modeled composite score only.
