The verdict

Two federal records point in the busier direction for Washington County. Its 30 FEMA declarations are 16% above the Mississippi county mean and exceed the count for 86% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it in the riskiest 17%, based on modeled expected annual loss, social vulnerability, and community resilience.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Washington County is led by Riverine Flooding (about $12.6M Expected Annual Loss, Historical Loss Ratio Very Low), while Tornado carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Washington County's hazard record show?

Reading the federal records together

FEMA's NFIP table contains a substantial paid-claim history for this county: 1,955 claims and $37.0M in payments. PlainHazard labels 500 or more claims a heavy registry record; that is a reporting bucket, not an official FEMA risk grade. The average paid claim was $18.9K. NFIP totals exclude uninsured flood losses and do not measure how many properties currently carry a policy.

The declaration register points in the busier direction. Washington County's 30 federal records stand 16% above the Mississippi county mean of 25.9. 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.

FEMA National Risk Index

This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 83.0/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Low (roughly $30.0M in annualized losses). Social vulnerability reads Very High and community resilience Relatively Moderate, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Tornado stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at roughly once every 1 years here, based on 29 historical events on record.

Declaration frequency

The FEMA register is busy by both local and national comparisons. It contains 30 entries for Washington County, including 23 Major Disaster records, 16% above the Mississippi county mean. Across the 55-year span, that works out to 0.5 declarations a year. Severe Storm leads the file with 11 entries. Declaration type records the federal action taken, not every assistance program approved.

How often does each hazard strike Washington 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.

Tornado Relatively High roughly once every 1 years
Earthquake Relatively Moderate roughly once every 329 years
Drought Relatively High 15 modeled event-days per year
Hail Relatively Moderate an average of 3.1 times per year
Heat Wave Relatively Moderate 19 modeled event-days per year
Strong Wind Relatively Moderate an average of 2.4 times per year
Riverine Flooding Relatively Moderate an average of 1.9 times per year

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Washington County's record, 37% 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: Tornado

Tornado exposure is the most spatially concentrated in the model: total destruction along a narrow corridor with intact property either side. County-level averages therefore understate severity badly for anyone actually in the path, and overstate it for everyone else.

For Washington County the two measures on this page point the same way: Tornado is the county's highest-rated modeled hazard (Relatively High), 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

Washington County's closest FEMA peer: Lincoln County, ME

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

What is the FEMA National Risk Index score for Washington County?
According to the FEMA National Risk Index, Washington County, Mississippi has an overall risk score of 83.0 out of 100 (Relatively Moderate). Social vulnerability here rates Very High, while community resilience comes in at Relatively Moderate. The Expected Annual Loss (EAL) score is Relatively Low, representing $30.0M in annualized losses.
Which natural hazard poses the greatest risk to Washington County?
The top hazard flagged by FEMA's NRI for Washington County as of the latest release is Tornado (risk rating: Relatively High). Other significant hazards include Earthquake (Relatively Moderate) and Drought (Relatively High). FEMA's modeled event frequency puts tornado here at roughly once every 1 years, drawn from 29 historical events on record.

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 Washington County

Washington County, MS has 30 federal declaration records, 16% more than the Mississippi county mean of 26; its history sits in PlainHazard's high activity band.

  • Within this above-state-average declaration file, major disaster leads with 23 of 30 records; the category describes past federal action, not the next likely hazard. Mississippi overview
  • The state benchmark and national rank point the same way: this count tops the Mississippi mean and the totals for 86% of 3,266 U.S. counties. Most-disaster rankings
  • The large NFIP claims file and FEMA declaration history measure different federal records; the guide explains where they overlap and where they do not. Disaster-data guide

An above-average declaration count records past federal responses; it does not predict the next event. Current warnings come from the National Weather Service and local emergency officials.
