Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Washington County is led by Riverine Flooding (about $1.6M Expected Annual Loss, Historical Loss Ratio Very High), while Hail carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Washington County's hazard record show?

FEMA National Risk Index

FEMA's National Risk Index places this county in the low end of the national distribution, composite score 12.0/100 (Very Low). Expected Annual Loss is rated Very Low (roughly $4.3M in annualized losses). Two modifiers shape how that exposure becomes real-world harm here: social vulnerability (Relatively High) and community resilience (Relatively Moderate). Among the 18 modeled hazards, Hail carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 6.6 times per year here, based on 250 historical events on record.

Reading the federal records together

No paid-claim row for this county appears in the NFIP county table used by PlainHazard. That absence is not evidence that flooding never occurred: the register observes claims under federal flood-insurance policies, not uninsured losses, emergency reports, or every flood outside the program. The FEMA declaration history below is therefore the available federal-action record on this page.

The declaration register points in the busier direction. Washington County's 13 federal records stand 27% above the Colorado county mean of 10.2. 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 Washington 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
Hail Relatively Moderate an average of 6.6 times per year
Strong Wind Relatively Moderate an average of 1.9 times per year
Wildfire Very Low roughly once every 1,582 years
Cold Wave Relatively Low an average of 2.7 times per year
Drought Relatively Low 53 modeled event-days per year
Winter Weather Relatively Low an average of 11 times per year
Ice Storm Relatively Low roughly once every 11 years
Tornado Relatively Low an average of 3.2 times per year
Earthquake Very Low roughly once every 2,688 years
Riverine Flooding Very Low roughly once every 1 years

What Flood declarations mean here

Flood is the most frequent declaration type on Washington County's record, 46% of its declarations. Federal flood declarations cover two mechanisms that behave very differently: riverine flooding, which builds over days as a watershed drains and is usually forecast well in advance, and flash flooding, which can arrive in under an hour from rainfall that fell somewhere upstream.

Flood is also the one hazard class where a second federal dataset exists for the same events. The National Flood Insurance Program records what was actually paid on insured losses, so it measures a narrower thing than the declaration count: uninsured damage, and flooding outside mapped special flood hazard areas, never enters it. Reading the two together is more informative than either alone.

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: Hail

Hail is among the most expensive hazards in the model relative to how little it threatens life. It concentrates on roofs, vehicles and crops, and a single severe storm can generate an insurance loss across a metropolitan area without a single injury.

Worth noting for Washington County: the model and the federal record do NOT point at the same hazard. Hail carries the highest modeled rating (Relatively Moderate), while the county's declaration history is led by Flood. 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.

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

What is the FEMA National Risk Index score for Washington County?
According to the FEMA National Risk Index, Washington County, Colorado has an overall risk score of 12.0 out of 100 (Very Low). Social vulnerability here rates Relatively High, while community resilience comes in at Relatively Moderate. The Expected Annual Loss (EAL) score is Very Low, representing $4.3M in annualized losses.
Which natural hazard poses the greatest risk to Washington County?
FEMA's NRI data points to Washington County as of the latest release is Hail (risk rating: Relatively Moderate). Other significant hazards include Strong Wind (Relatively Moderate) and Wildfire (Very Low). FEMA's modeled event frequency puts hail here at an average of 6.6 times per year, drawn from 250 historical events on record. The underlying methodology weighs historical event frequency against exposed assets and community vulnerability.
