The verdict

Start with the local benchmark for Montrose County: 9 FEMA declaration records are 12% below the Colorado county mean, even though the count is higher than 8% of counties in the national registry. On FEMA's distinct National Risk Index model, which combines expected loss with vulnerability and resilience, the county ranks safer than 49%.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Montrose County is led by Riverine Flooding (about $11.8M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Lightning carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Montrose County's hazard record show?

FEMA National Risk Index

FEMA's data shows an elevated National Risk Index composite of 49.0/100 for this county (Relatively Low rating). Expected Annual Loss comes in at Relatively Low (roughly $15.6M in annualized losses). Social vulnerability (Relatively Low) and community resilience (Relatively Low) both factor into how that raw exposure plays out on the ground. Of the 18 hazards FEMA models, Lightning stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 53 times per year here, based on 105,704 historical events on record.

Declaration frequency

The state comparison is the clearest context for Montrose County's moderate federal record. Its 9 declarations sit 12% below the Colorado county mean, with 5 Major Disaster entries among them. 3 records concern Flood, the file's most frequent incident type. Spread across 50 years, the registry rate is 0.2 per year. FEMA reports authorized programs separately from the DR, EM, and FM codes.

Reading the federal records together

This county has a small entry in FEMA's NFIP paid-claims table: 6 claims and $60.1K 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.

Start with the state benchmark: a Colorado county averages 10.2 federal declaration records, while Montrose County has 9. The gap is 12% 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.

How often does each hazard strike Montrose 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
Lightning Relatively High an average of 53 times per year
Landslide Relatively Low an average of 1.4 times per year
Avalanche Relatively Moderate an average of 1.1 times per year
Wildfire Relatively Low roughly once every 1,083 years
Earthquake Relatively Low roughly once every 577 years
Riverine Flooding Relatively Low an average of 1.2 times per year
Drought Relatively Low 82 modeled event-days per year
Winter Weather Relatively Low an average of 17 times per year
Cold Wave Very Low roughly once every 60 years
Ice Storm Very Low roughly once every 67 years
Heat Wave Very Low 0.1 modeled event-days per year

What Flood declarations mean here

Flood is the most frequent declaration type on Montrose County's record, 33% 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: Lightning

Lightning is modeled as a high-frequency, low-per-event hazard: strike counts are large, but each strike affects a very small area. Its aggregate cost accumulates through structure fires, electrical and electronic damage, and it is one of the few hazards whose risk is essentially continuous through the season rather than episodic.

Worth noting for Montrose County: the model and the federal record do NOT point at the same hazard. Lightning carries the highest modeled rating (Relatively High), 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.

Data-matched county comparisons

Montrose County's closest FEMA peer: Gallatin County, MT

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

Data Sources & Methodology

Disaster declaration data comes from the FEMA OpenFEMA Disaster Declarations Summaries v2 API, which includes all federally declared disasters, emergencies, and fire management assistance grants.

Storm event data is sourced from the NOAA Storm Events Database (2015-2025), which tracks significant weather events including thunderstorms, tornadoes, floods, and winter storms.

Flood insurance data comes from the FEMA National Flood Insurance Program (NFIP) OpenFEMA claims dataset.

This data is provided for informational purposes only. FEMA disaster declarations represent federal response actions and may not capture all local emergencies or weather events.

What this means for Montrose County

Against a Colorado county mean of 10 declarations, Montrose County, CO records 9, or 12% fewer. PlainHazard classifies that historical total as moderate activity.

  • Major Disaster is the largest group (5 of 9) in a declaration history that remains below its state benchmark; frequency here is not a forecast. Colorado overview
  • Nationally the county exceeds 8% of recorded county totals, but its own Colorado benchmark is higher. The ranking keeps those two contexts separate. Most-disaster rankings
  • A short NFIP claims file cannot establish low flood exposure; the data guide explains the limits of each federal measure. Disaster-data guide

A below-average federal record is not a safety guarantee. Use National Weather Service alerts and local emergency-management notices for present conditions, not this historical comparison.
