The verdict

Two federal records point in the busier direction for Mobile County. Its 40 FEMA declarations are 55% above the Alabama county mean and exceed the count for 97% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it in the riskiest 2%, based on modeled expected annual loss, social vulnerability, and community resilience.

What does Mobile County's hazard record show?

Reading the federal records together

FEMA's NFIP table contains a substantial paid-claim history for this county: 15,116 claims and $368.3M 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 $24.4K. 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. Mobile County's 40 federal records stand 55% above the Alabama county mean of 25.8. 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 98.0/100 (Relatively High). Expected Annual Loss is rated Relatively High (roughly $298.2M in annualized losses). Social vulnerability reads Relatively Moderate and community resilience Relatively High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Hurricane stands out as the sharpest exposure here, rated Very High. FEMA's modeled frequency puts that hazard at roughly once every 4 years here, based on 98 historical events on record.

How often does each hazard strike Mobile 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.

Hurricane Very High roughly once every 4 years
Lightning Very High an average of 85 times per year
Heat Wave Relatively Moderate 10 modeled event-days per year
Riverine Flooding Relatively High an average of 3.7 times per year
Tornado Relatively High an average of 1.2 times per year
Wildfire Relatively Moderate roughly once every 241 years
Coastal Flooding Relatively High an average of 4.8 times per year
Drought Relatively Moderate 17 modeled event-days per year
Cold Wave Relatively Moderate roughly once every 1 years
Earthquake Relatively Low roughly once every 853 years
Hail Relatively Moderate an average of 1.7 times per year

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on Mobile County's federal record, 63% 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: Hurricane

Hurricane exposure in the model bundles the three ways a tropical system does harm, which arrive on different timescales and are insured differently: wind, storm surge on the coast, and rainfall flooding that can reach far inland well after landfall.

For Mobile County the two measures on this page point the same way: Hurricane is the county's highest-rated modeled hazard (Very High), and Hurricane 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

Mobile County's closest FEMA peer: Tulsa County, OK

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