The verdict

Yalobusha County has a nationally busy FEMA history: 20 declarations, more than 46% of counties in this registry. But the state comparison tempers that reading: the total is 23% below the Mississippi county mean. FEMA's separate National Risk Index places the county safer than 20%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Yalobusha County is led by Riverine Flooding (about $1.8M Expected Annual Loss, Historical Loss Ratio Relatively Low), while Lightning carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Yalobusha County's hazard record show?

FEMA National Risk Index

This county's FEMA National Risk Index composite lands at 19.5/100 (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 Relatively High social-vulnerability score and Relatively Low community-resilience score. Among the 18 modeled hazards, Lightning carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 65 times per year here, based on 52,919 historical events on record.

Reading the federal records together

This county has a small entry in FEMA's NFIP paid-claims table: 39 claims and $363.8K 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.

Start with the state benchmark: a Mississippi county averages 25.9 federal declaration records, while Yalobusha County has 20. The gap is 23% 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 Yalobusha 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 Moderate an average of 65 times per year
Earthquake Relatively Low roughly once every 277 years
Heat Wave Relatively Low 19 modeled event-days per year
Landslide Very Low an average of 1 time per year
Hurricane Very Low roughly once every 14 years
Tornado Relatively Low roughly once every 3 years
Cold Wave Relatively Low an average of 1.1 times per year
Drought Relatively Low 13 modeled event-days per year
Wildfire Very Low roughly once every 732 years

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Yalobusha County's record, 30% 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: 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.

For Yalobusha County the two measures on this page point the same way: Lightning 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-matched county comparisons

Yalobusha County's closest FEMA peer: Fulton County, IL

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