Cobb County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Cobb County is led by Riverine Flooding (about $125.3M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Tornado carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Cobb County's hazard record show?
Reading the federal records together
FEMA's NFIP table contains a substantial paid-claim history for this county: 2,029 claims and $66.9M 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 $33.0K. 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. Cobb County's 19 federal records stand 9% above the Georgia county mean of 17.4. 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 94.4/100 (Relatively High). Expected Annual Loss is rated Relatively High (roughly $209.6M in annualized losses). Social vulnerability reads Very Low and community resilience Relatively Low, 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 5 years here, based on 25 historical events on record.

How often does each hazard strike Cobb 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 |
|---|---|---|
| Tornado | Relatively High | roughly once every 5 years |
| Hail | Relatively High | an average of 5.6 times per year |
| Lightning | Very High | an average of 62 times per year |
| Cold Wave | Relatively High | an average of 1.1 times per year |
| Riverine Flooding | Relatively High | an average of 1.3 times per year |
| Ice Storm | Relatively High | an average of 1.2 times per year |
| Earthquake | Relatively Moderate | roughly once every 431 years |
| Heat Wave | Relatively Moderate | 2.2 modeled event-days per year |
| Strong Wind | Relatively Moderate | an average of 2.8 times per year |
| Landslide | Relatively Low | roughly once every 3 years |
| Winter Weather | Relatively Moderate | an average of 2.8 times per year |
| Hurricane | Relatively Low | roughly once every 28 years |
| Wildfire | Very Low | roughly once every 7,086 years |

What Hurricane declarations mean here
Hurricane is the most frequent declaration type on Cobb County's federal record, 26% of its declarations. Atlantic tropical systems run on a defined season, 1 June to 30 November, with most activity concentrated between August and October; Pacific and territorial basins run on their own calendars. A single named storm routinely produces one declaration number covering a long corridor of counties at once, well inland as well as on the coast, which is why an affected county's count can jump by several in one year without several separate events having occurred.
One practical distinction matters when reading these records: a tropical declaration usually bundles wind, storm surge and inland rainfall flooding under a single incident, but the insurance behind them is split. Wind damage falls to property insurers, while flood and surge damage is covered only under a separate National Flood Insurance Program policy. That is why a county can show heavy declaration activity and a comparatively small NFIP claims record, or the reverse.
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.
Worth noting for Cobb County: the model and the federal record do NOT point at the same hazard. Tornado carries the highest modeled rating (Relatively High), while the county's declaration history is led by Hurricane. 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.

What is the FEMA National Risk Index score for Cobb County?
According to the FEMA National Risk Index, Cobb County, Georgia has an overall risk score of 94.4 out of 100 (Relatively High). On social vulnerability the county rates Very Low; on community resilience, Relatively Low. The Expected Annual Loss (EAL) score is Relatively High, representing $209.6M in annualized losses.
Which natural hazard poses the greatest risk to Cobb County?
Based on FEMA NRI data, the highest-risk natural hazard in Cobb County as of the latest release is Tornado (risk rating: Relatively High). Other significant hazards include Hail (Relatively High) and Lightning (Very High). FEMA's modeled event frequency puts tornado here at roughly once every 5 years, drawn from 25 historical events on record. FEMA derives these ratings from historical event frequency, the assets exposed, and the community's vulnerability profile.
