The verdict
Two federal records point in the busier direction for Grayson County. Its 29 FEMA declarations are 3% above the Kentucky county mean and exceed the count for 85% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it safer than 45%, based on modeled expected annual loss, social vulnerability, and community resilience.

Grayson County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Grayson County is led by Riverine Flooding (about $5.0M Expected Annual Loss, Historical Loss Ratio Relatively 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 Grayson County's hazard record show?
FEMA National Risk Index
FEMA's data shows an elevated National Risk Index composite of 45.3/100 for this county (Relatively Low rating). Expected Annual Loss comes in at Very Low (roughly $11.4M in annualized losses). Social vulnerability (Relatively High) and community resilience (Relatively Moderate) both factor into how that raw exposure plays out on the ground. 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 3.1 times per year here, based on 119 historical events on record.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 6 claims and $155.8K 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.
The declaration register points in the busier direction. Grayson County's 29 federal records stand 3% above the Kentucky county mean of 28.1. 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 Grayson 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 3.1 times per year |
| Ice Storm | Relatively Moderate | an average of 1.1 times per year |
| Strong Wind | Relatively Moderate | an average of 6 times per year |
| Tornado | Relatively Moderate | roughly once every 3 years |
| Earthquake | Relatively Low | roughly once every 360 years |
| Heat Wave | Relatively Low | 5.9 modeled event-days per year |
| Cold Wave | Relatively Low | roughly once every 1 years |
| Riverine Flooding | Relatively Low | an average of 1.1 times per year |
| Landslide | Very Low | roughly once every 1 years |
| Winter Weather | Relatively Low | an average of 7.8 times per year |
| Lightning | Relatively Low | an average of 54 times per year |
| Hurricane | Very Low | roughly once every 87 years |
| Drought | Very Low | 1.6 modeled event-days per year |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Grayson County's record, 55% 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: 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.
For Grayson County the two measures on this page point the same way: Hail is the county's highest-rated modeled hazard (Relatively Moderate), and Severe Storm declarations also lead its federal record. Where the model and the declaration history agree, the reading is comparatively straightforward, the hazard is both expected and repeatedly realised.
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.
