The verdict
Dimmit County has a nationally busy FEMA history: 18 declarations, more than 37% of counties in this registry. But the state comparison tempers that reading: the total is 14% below the Texas county mean. FEMA's separate National Risk Index places the county safer than 36%; that score models loss and vulnerability rather than counting declarations.

Dimmit County's FEMA Risk Index score
What does Dimmit County's hazard record show?
FEMA National Risk Index
FEMA's data shows an elevated National Risk Index composite of 35.9/100 for this county (Very Low rating). Expected Annual Loss comes in at Very Low (roughly $6.3M in annualized losses). Social vulnerability (Very High) and community resilience (Very Low) both factor into how that raw exposure plays out on the ground. Among the 18 modeled hazards, Heat Wave carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at 7.1 modeled event-days per year here, based on 130 historical events on record.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 10 claims and $474.1K paid in total. PlainHazard calls 1-49 claims a light registry record, a label for this dataset rather than a finding that flood exposure is low. A short claims history can also reflect insurance take-up, the period covered, or losses that were never insured.
Start with the state benchmark: a Texas county averages 20.9 federal declaration records, while Dimmit County has 18. The gap is 14% below that mean. Fewer entries indicate a quieter history of recorded federal actions, not immunity from a hazard and not a prediction about what happens next.

How often does each hazard strike Dimmit 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 |
|---|---|---|
| Heat Wave | Relatively Moderate | 7.1 modeled event-days per year |
| Drought | Relatively Moderate | 106 modeled event-days per year |
| Hurricane | Relatively Low | roughly once every 23 years |
| Wildfire | Very Low | roughly once every 698 years |
| Cold Wave | Relatively Low | roughly once every 3 years |
| Lightning | Relatively Low | an average of 35 times per year |
| Tornado | Relatively Low | roughly once every 10 years |
| Ice Storm | Very Low | roughly once every 16 years |
| Hail | Very Low | roughly once every 1 years |
| Riverine Flooding | Very Low | an average of 1.7 times per year |
| Winter Weather | Very Low | an average of 1.1 times per year |
| Earthquake | Very Low | roughly once every 5,405 years |
| Strong Wind | Very Low | roughly once every 4 years |
| Landslide | Very Low | roughly once every 9 years |

What Hurricane declarations mean here
Hurricane is the most frequent declaration type on Dimmit County's federal record, 22% 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: Heat Wave
Heat Wave is measured in event-days per year rather than discrete events, and it is the hazard whose harm is most consistently undercounted: its toll is health and mortality, concentrated among people without cooling, rather than visible damage to property.
Worth noting for Dimmit County: the model and the federal record do NOT point at the same hazard. Heat Wave carries the highest modeled rating (Relatively Moderate), 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.
