The verdict
Johnston County has a nationally busy FEMA history: 21 declarations, more than 52% of counties in this registry. But the state comparison tempers that reading: the total is 35% below the Oklahoma county mean. FEMA's separate National Risk Index places the county safer than 25%; that score models loss and vulnerability rather than counting declarations.

Johnston County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Johnston County is led by Riverine Flooding (about $1.5M Expected Annual Loss, Historical Loss Ratio Relatively High), while Ice Storm carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Johnston County's hazard record show?
FEMA National Risk Index
This county's FEMA National Risk Index composite lands at 25.4/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $5.5M in annualized losses), tempered or compounded by a Very High social-vulnerability score and Relatively Low community-resilience score. Of the 18 hazards FEMA models, Ice Storm stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 1.6 times per year here, based on 106 historical events on record.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 4 claims and $223.0K 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 Oklahoma county averages 32.2 federal declaration records, while Johnston County has 21. The gap is 35% 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 Johnston 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 |
|---|---|---|
| Ice Storm | Relatively High | an average of 1.6 times per year |
| Wildfire | Relatively Low | roughly once every 143 years |
| Drought | Relatively Moderate | 45 modeled event-days per year |
| Heat Wave | Relatively Low | 20 modeled event-days per year |
| Hail | Relatively Low | an average of 7.1 times per year |
| Tornado | Relatively Low | roughly once every 2 years |
| Landslide | Very Low | roughly once every 7 years |
| Earthquake | Very Low | roughly once every 720 years |
| Strong Wind | Relatively Low | an average of 3 times per year |
| Cold Wave | Relatively Low | an average of 1.2 times per year |
| Hurricane | Very Low | roughly once every 140 years |
| Winter Weather | Relatively Low | an average of 5.9 times per year |
| Lightning | Relatively Low | an average of 55 times per year |
| Riverine Flooding | Very Low | roughly once every 1 years |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Johnston County's record, 33% 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 Johnston County: the model and the federal record do NOT point at the same hazard. Ice Storm carries the highest modeled rating (Relatively 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.
