19 FEMA disaster declarations (1967-2024), with a FEMA National Risk Index rating of Relatively High. Most common hazard: Severe Storm.
The verdict
Two federal records point in the busier direction for Will County. Its 19 FEMA declarations are 48% above the Illinois county mean and exceed the count for 41% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it in the riskiest 3%, based on modeled expected annual loss, social vulnerability, and community resilience.
FEMA's National Risk Index and its declaration registry are separate measures. This county's registry includes Major Disaster (DR) and Emergency (EM) records; an EM authorizes a narrower set of federal assistance than a DR.

FEMA's modeled annual dollar loss for Will County is led by Riverine Flooding (about $193.0M Expected Annual Loss, Historical Loss Ratio Relatively High), while Cold Wave carries the highest National Risk Index rating (Very High). EAL and risk score use different inputs; they need not agree.

FEMA's NFIP table contains a substantial paid-claim history for this county: 2,294 claims and $21.1M 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 $9.2K. 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. Will County's 19 federal records stand 48% above the Illinois county mean of 12.9. 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.
This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 97.3/100 (Relatively High). Expected Annual Loss is rated Relatively High (roughly $348.1M in annualized losses). Social vulnerability reads Very Low and community resilience Very High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Cold Wave stands out as the sharpest exposure here, rated Very High. FEMA's modeled frequency puts that hazard at an average of 4.3 times per year here, based on 82 historical events on record.

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 |
|---|---|---|
| Cold Wave | Very High | an average of 4.3 times per year |
| Tornado | Very High | roughly once every 2 years |
| Riverine Flooding | Relatively High | an average of 3 times per year |
| Heat Wave | Relatively Moderate | 3.6 modeled event-days per year |
| Winter Weather | Relatively High | an average of 14 times per year |
| Earthquake | Relatively Moderate | roughly once every 685 years |
| Lightning | Relatively High | an average of 45 times per year |
| Ice Storm | Relatively Moderate | roughly once every 1 years |
| Hail | Relatively Low | an average of 3.9 times per year |
| Landslide | Very Low | roughly once every 6 years |
| Wildfire | Very Low | roughly once every 3,218 years |
| Strong Wind | Relatively Low | an average of 5.6 times per year |
| Drought | Relatively Low | 1.6 modeled event-days per year |
| Hurricane | Very Low | roughly once every 107 years |

Severe Storm is the most frequent declaration type on Will County's record, 26% 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.
FEMA categorizes declarations as Major Disasters (DR), Emergencies (EM), or Fire Management Assistance (FM).

Cold Wave measures exposure to extreme cold rather than to snow. Its harm is concentrated in health effects, burst infrastructure and energy demand spikes, and it falls hardest where the building stock and the grid were not built with sustained cold in mind.
Worth noting for Will County: the model and the federal record do NOT point at the same hazard. Cold Wave 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-matched county comparisons
Comparisons use published FEMA declaration fields plus the National Risk Index composite for Will County. Record similarity, not a safety rating.
Will County: NRI composite 97.3 (Relatively High).
Will County: 14 of 19 of its declarations are Major.
Will County shows 19 FEMA declarations, led by Severe Storm.
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.

Understanding disaster data
Will County's NFIP claims file (2,294 claims) and FEMA declaration history measure different federal records - this guide separates them from modeled NRI risk.
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.
