The verdict

Two federal records point in the busier direction for Montgomery County. Its 24 FEMA declarations are 18% above the Virginia county mean and exceed the count for 66% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it safer than 48%, based on modeled expected annual loss, social vulnerability, and community resilience.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Montgomery County is led by Riverine Flooding (about $11.2M Expected Annual Loss, Historical Loss Ratio Relatively Low), while Landslide carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Montgomery County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 181 paid claims, totaling $3.2M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $17.8K 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. Montgomery County's 24 federal records stand 18% 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.

FEMA National Risk Index

FEMA's data shows an elevated National Risk Index composite of 47.5/100 for this county (Relatively Low rating). Expected Annual Loss comes in at Relatively Low (roughly $16.6M in annualized losses). Social vulnerability (Relatively Low) and community resilience (Relatively Moderate) both factor into how that raw exposure plays out on the ground. Among the 18 modeled hazards, Landslide carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 1 time per year here.

How often does each hazard strike Montgomery 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.

Earthquake Relatively Low roughly once every 706 years

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Montgomery County's record, 25% 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: Landslide

Landslide risk is a function of slope, soil and water, so it is usually a SECOND-ORDER hazard: it is triggered by the rainfall, snowmelt, wildfire burn scars or seismic shaking that came first. That is why a county can carry high landslide exposure whose realized damage is recorded under a flood or storm declaration instead.

Worth noting for Montgomery County: the model and the federal record do NOT point at the same hazard. Landslide 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.

Data-matched county comparisons

Montgomery County's closest FEMA peer: Delaware County, PA

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Montgomery 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.
