Ohio Natural Disasters
Ohio's federal declaration record sits near the middle of the state distribution. 60 FEMA disaster declarations are on record, led by severe storm, with $969.9M in combined property and crop damage. A moderate count like this can still mask a single catastrophic year rather than a steady annual pattern. NOAA storm event data shows 16,184 recorded weather events resulting in 71 fatalities, a toll that informs where the state directs disaster-preparedness resources.

The Ohio risk picture
3 of the 88 counties FEMA scores, 3%, carry a FEMA "high-risk" National Risk Index rating, with riverine flooding the single largest driver of expected annual loss statewide. Ohio has 52 Major Disaster (DR) declarations; FEMA authorizes Individual Assistance, Public Assistance, or both separately for each declaration. NOAA-tracked storms have caused 426 injuries statewide.

FEMA's National Risk Index and NOAA's Storm Events Database measure different things: modeled long-run risk vs. observed severe-weather events. Storm Events is a reported dataset, so its counts track what was observed and logged, not every event that occurred, and reporting is denser where more people live. See the methodology for how they relate.

The declaration chart counts past federal actions. The county score chart summarizes FEMA's modeled National Risk Index composite; it is not a forecast, and a state average does not describe every county.
Do more storms mean more federal disasters?
Ohio sits at the 31st percentile of FEMA declaration volume and the 65th percentile of NOAA storm-event volume among 55 states and territories, those two ranks are not interchangeable.

What does Ohio's hazard record show?
Flood exposure & where to dig deeper
Flood exposure is quantified separately through the National Flood Insurance Program. Policyholders across 88Ohio counties have filed 28,011 NFIP claims totaling $369.2M, or an average of $13.2K per claim. NFIP data captures only insured flood losses, so uninsured flood damage and storm-surge losses outside mapped high-risk zones remain invisible in this figure. The highest-Expected-Annual-Loss hazard across the state is Riverine Flooding, estimated at $1.9B annually. Drill into individual counties for localized risk, read FEMA's hazard-specific briefings, and review insurance and flood-zone designations, state-level averages can mask sharp county-to-county differences in exposure and resilience.
NOAA storm events & FEMA National Risk Index
NOAA's Storm Events Database adds the near-term severe-weather lens. Between 2015 and 2025, Ohio recorded 16,184 individual storm events, causing 71 fatalities and 426 injuries, with combined property and crop damage estimated at $969.9M. The most frequent event types in the state are Thunderstorm Wind (6,938 events), Winter Weather (2,101 events), Hail (1,749 events). Across the 88counties FEMA scores here, its National Risk Index flags 3 as high-risk, with an average county Risk Index score (FEMA's own formula, distinct from our Historical Activity tool below) of 55.0/100.
What this count is, and is not. Storm Events is a reported database: NOAA compiles it from National Weather Service offices, trained spotters, law enforcement, and the public. It is a record of what was observed and logged, not a complete census of severe weather. Densely populated areas report more events than sparsely populated ones with similar meteorological exposure, and detection has improved over time, so an event count is not a like-for-like measure of hazard between places or across decades. Damage figures are field estimates, not audited losses. See methodology.
FEMA disaster declarations
Ohio (OH) has a moderate level of federal declaration activity, with 60 FEMA declaration records, including 52 Major Disaster declarations (DR). A DR may authorize Individual Assistance, Public Assistance, or both; those program approvals are not implied by the DR count. The dominant declaration type is Severe Storm, followed by Flood (17), Tornado (8), Snowstorm (4). Declaration counts at the state level reflect the cumulative federal footprint: large multi-county events count once per state, but repeat hazard patterns across decades are visible in the breakdown below.
