Colorado Natural Disasters

Colorado carries a substantial federal disaster record. 111 FEMA disaster declarations are on record, led by fire, with $5.8B in combined property and crop damage. The count also reflects declaration policy and program use; it is not a direct measure of physical hazard frequency. NOAA storm event data shows 18,340 recorded weather events resulting in 105 fatalities, figures the state uses to prioritize disaster-preparedness planning.

The Colorado risk picture

2 of the 64 counties FEMA scores, 3%, carry a FEMA "high-risk" National Risk Index rating, with riverine flooding the single largest driver of expected annual loss statewide. Colorado has 25 Major Disaster (DR) declarations; FEMA authorizes Individual Assistance, Public Assistance, or both separately for each declaration. NOAA-tracked storms have caused 777 injuries statewide.

FEMA's National Risk Index and NOAA's Storm Events Database measure different things: modeled long-run risk vs. observed severe-weather events. Storm Events is a reported dataset, so its counts track what was observed and logged, not every event that occurred, and reporting is denser where more people live. See the methodology for how they relate.

Do more storms mean more federal disasters?

Colorado sits at the 78th percentile of FEMA declaration volume and the 73rd percentile of NOAA storm-event volume among 55 states and territories, those two ranks are not interchangeable.

What does Colorado's hazard record show?

NOAA storm events & FEMA National Risk Index

NOAA's Storm Events Database adds the near-term severe-weather lens. Between 2015 and 2025, Colorado recorded 18,340 individual storm events, causing 105 fatalities and 777 injuries, with combined property and crop damage estimated at $5.8B. The most frequent event types in the state are Hail (4,913 events), Winter Weather (2,620 events), High Wind (1,992 events). Across the 64counties FEMA scores here, its National Risk Index flags 2 as high-risk, with an average county Risk Index score (FEMA's own formula, distinct from our Historical Activity tool below) of 40.7/100.

What this count is, and is not. Storm Events is a reported database: NOAA compiles it from National Weather Service offices, trained spotters, law enforcement, and the public. It is a record of what was observed and logged, not a complete census of severe weather. Densely populated areas report more events than sparsely populated ones with similar meteorological exposure, and detection has improved over time, so an event count is not a like-for-like measure of hazard between places or across decades. Damage figures are field estimates, not audited losses. See methodology.

FEMA disaster declarations

Colorado (CO) has a high level of federal declaration activity, with 111 FEMA declaration records, including 25 Major Disaster declarations (DR). A DR may authorize Individual Assistance, Public Assistance, or both; those program approvals are not implied by the DR count. The dominant declaration type is Fire, followed by Flood (14), Snowstorm (3), Severe Storm (3). Declaration counts at the state level reflect the cumulative federal footprint: large multi-county events count once per state, but repeat hazard patterns across decades are visible in the breakdown below.

Flood exposure & where to dig deeper

Flood exposure is quantified separately through the National Flood Insurance Program. Policyholders across 53Colorado counties have filed 5,556 NFIP claims totaling $90.2M, or an average of $16.2K per claim. NFIP data captures only insured flood losses, so uninsured flood damage and storm-surge losses outside mapped high-risk zones remain invisible in this figure. The highest-Expected-Annual-Loss hazard across the state is Riverine Flooding, estimated at $1.0B annually. Drill into individual counties for localized risk, read FEMA's hazard-specific briefings, and review insurance and flood-zone designations, state-level averages can mask sharp county-to-county differences in exposure and resilience.

Highest-risk counties by FEMA National Risk Index

Declaration counts above measure past federal action; FEMA's NRI is a composite of Expected Annual Loss, social vulnerability, and community resilience. By that separate measure the highest-risk counties in Colorado are Denver (Relatively High), Jefferson (Relatively High), El Paso (Relatively Moderate), Arapahoe (Relatively Moderate), Adams (Relatively Moderate). Compare any county's recorded history with the Historical Activity tool.
