The verdict
Mayes County has a nationally busy FEMA history: 31 declarations, more than 88% of counties in this registry. But the state comparison tempers that reading: the total is 4% below the Oklahoma county mean. FEMA's separate National Risk Index places the county in the riskiest 22%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Mayes County is led by Riverine Flooding (about $11.5M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Ice Storm carries the highest National Risk Index rating (Very High). EAL and risk score use different inputs; they need not agree.

What does Mayes County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 122 paid claims, totaling $3.3M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $27.0K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.
Start with the state benchmark: a Oklahoma county averages 32.2 federal declaration records, while Mayes County has 31. The gap is 4% 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.
FEMA National Risk Index
This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 77.6/100 (Relatively Low). Expected Annual Loss is rated Relatively Low (roughly $26.2M in annualized losses). Social vulnerability reads Very High and community resilience Relatively Low, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Ice Storm stands out as the sharpest exposure here, rated Very High. FEMA's modeled frequency puts that hazard at an average of 1.4 times per year here, based on 97 historical events on record.
Declaration frequency
Nationally, Mayes County's 31 FEMA records form a high-volume history; within Oklahoma, however, the count is 4% below the county mean. 23 entries carry the Major Disaster classification. The largest incident group is Severe Storm, appearing 15 times. The full 51-year record averages 0.6 declarations annually. A DR label alone does not say whether Individual Assistance, Public Assistance, or both followed.

How often does each hazard strike Mayes 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.

|---|---|---|
| Ice Storm | Very High | an average of 1.4 times per year |
| Strong Wind | Relatively High | an average of 7.5 times per year |
| Heat Wave | Relatively Moderate | 23 modeled event-days per year |
| Tornado | Relatively Moderate | roughly once every 1 years |
| Lightning | Relatively High | an average of 55 times per year |
| Wildfire | Relatively Low | roughly once every 205 years |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Mayes County's record, 48% 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: Ice Storm
Ice storms load power lines and tree limbs with accumulating freezing rain until they fail. The characteristic cost is infrastructure and multi-day power loss across a wide area rather than structural damage to buildings, which is why their consequences often outlast the weather that caused them.
Worth noting for Mayes County: the model and the federal record do NOT point at the same hazard. Ice Storm carries the highest modeled rating (Very High), 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 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 Mayes County
Against a Oklahoma county mean of 32 declarations, Mayes County, OK records 31, or 4% fewer. PlainHazard classifies that historical total as high activity.
- Major Disaster is the largest group (23 of 31) in a declaration history that remains below its state benchmark; frequency here is not a forecast. Oklahoma overview
- Nationally the county exceeds 88% of recorded county totals, but its own Oklahoma benchmark is higher. The ranking keeps those two contexts separate. Most-disaster rankings
