Warren County's FEMA Risk Index score
What does Warren County's hazard record show?
Reading the federal records together
FEMA's NFIP table contains a substantial paid-claim history for this county: 2,688 claims and $35.6M 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 $13.2K. 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. Warren County's 33 federal records stand 27% 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 86.3/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Low (roughly $42.5M in annualized losses). Social vulnerability reads Very High and community resilience Very High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Drought stands out as the sharpest exposure here, rated Very High. FEMA's modeled frequency puts that hazard at 14 modeled event-days per year here, based on 462 historical events on record.

How often does each hazard strike Warren 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 |
|---|---|---|
| Drought | Very High | 14 modeled event-days per year |
| Hail | Relatively High | an average of 4 times per year |
| Tornado | Relatively High | roughly once every 1 years |
| Strong Wind | Relatively High | an average of 3.5 times per year |
| Heat Wave | Relatively Moderate | 19 modeled event-days per year |
| Landslide | Relatively Low | roughly once every 2 years |
| Ice Storm | Relatively Moderate | an average of 1 time per year |
| Lightning | Relatively Moderate | an average of 69 times per year |
| Earthquake | Relatively Low | roughly once every 530 years |
| Hurricane | Relatively Low | roughly once every 13 years |
| Riverine Flooding | Relatively Low | an average of 1.8 times per year |
| Cold Wave | Relatively Moderate | roughly once every 1 years |
| Wildfire | Very Low | roughly once every 4,740 years |
| Winter Weather | Very Low | an average of 2.4 times per year |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Warren County's record, 42% 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: Drought
Drought is the slowest of the modeled hazards and the least visible: it does its damage to agriculture, water supply and soil over seasons rather than hours, so it rarely produces the kind of single-day damage that drives a disaster declaration. FEMA scores it in event-days per year rather than discrete events for exactly that reason.
Worth noting for Warren County: the model and the federal record do NOT point at the same hazard. Drought 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.
