Hancock County, Mississippi: hazard history
What federal records show has already happened here: disaster declarations, storms, and flood insurance claims. This is a record of the past. It is not a forecast and not a hazard score.
At a glance
What this means
- The event NOAA recorded most often here is Thunderstorm Wind, with 97 records.
- The costliest single record is Storm Surge/Tide in 2005: $3.4B in property damage, in the dollars of that year.
- The deadliest record is Hurricane (Typhoon) in 2005, with 56 deaths.
- FEMA has declared 33 disasters that named this county, most often for hurricane.
- The worst year for flood insurance claims was 2005, with 5,305 claims.
What this can't tell you
- What happens next. Past events do not set the odds of the next one.
- Anything before 1996 from NOAA. That is when NOAA began recording every event type; earlier files hold only tornado, hail and wind, so they are left out on purpose.
- Today's cost. Damage and payments are in the dollars of the year they happened.
- A flood rate. NFIP counts claims but not how many homes were insured, and many flooded homes carry no flood insurance.
- Earthquakes, wildfire perimeters or radar-detected hail. Those records are not tied to counties.

Records start in 1996. Damage is NOAA's estimate at the time, in nominal dollars, and is often rounded; it is not insurance claims data. A storm that crossed two NOAA zones in this county is recorded, and counted, once per zone.

Each line is one NOAA record, linked to its page at NOAA. One large storm can appear more than once if NOAA recorded it in several zones of this county. Dollars are nominal.
Flood insurance claims (NFIP)
The National Flood Insurance Program paid $725.2M on 9,841 claims in Hancock County from 1978 to 2024.
| Year | Claims | Paid |
|---|---|---|
| 2005 | 5,305 | $684.5M |
| 2002 | 1,046 | $7.7M |

| 1998 | 544 | $2.2M |
A count of claims, not a rate: NFIP publishes no count of insured homes beside it, and most flood damage is uninsured. Nominal dollars. Records run from 1978 to 2024; claims filed without a county code are not on any county page. Source: FEMA OpenFEMA FIMA NFIP Redacted Claims.
Hazard vulnerability analysis: the probability column for a facility in Hancock County
A hazard vulnerability analysis rates each hazard for probability, impact, preparedness and response. Probability is the one column the county’s federal record can fill — NCEI storm events from 1996 to 2026 and FEMA declarations naming the county — and this is what it says for a facility here, on the 0–3 scale of the all-hazards structure surveyors expect. The other six columns are the facility’s own judgment about its building, and Calchis leaves them blank.
| Hazard | Prob. | Basis, from the county record |
|---|---|---|
| Hurricane / Tropical Storm | 3 | 53 NCEI events over 31 years (1.71/yr). 22 federal disaster declarations naming the county. |
| Tornado | 3 | 42 NCEI events over 31 years (1.35/yr). No federal disaster declaration of this kind has named the county. |
| Severe Thunderstorm | 3 | 153 NCEI events over 31 years (4.94/yr). 5 federal disaster declarations naming the county. |
| Flood, External | 3 | 43 NCEI events over 31 years (1.39/yr). 1 federal disaster declaration naming the county. |
| Temperature Extremes | 3 | 50 NCEI events over 31 years (1.61/yr). No federal disaster declaration of this kind has named the county. |
| Snow Fall / Blizzard / Ice Storm | 2 | 10 NCEI events over 31 years (0.32/yr). 1 federal disaster declaration naming the county. |
| Drought | 2 | 12 NCEI events over 31 years (0.39/yr). No federal disaster declaration of this kind has named the county. |
| Epidemic | 2 | 2 federal disaster declarations naming the county. |

A dash means the record does not speak to that hazard; it is not a zero. Whether a finished document satisfies the CMS Emergency Preparedness Rule is the facility’s finding and its surveyor’s. Complete the HVA for a facility in Hancock County — the technological, human and hazardous-materials rows, the six facility columns, the approval and the printed document — or read the sample analysis on that page first.
How this page was made
- Every figure is counted from public federal records held by Calchis: NOAA NCEI Storm Events, FEMA OpenFEMA Disaster Declarations, and FEMA NFIP claims. Nothing is modeled or estimated.
- NOAA files some events by county and others by forecast zone, and names both. Records are counted as Hancock County when their NOAA name is this county's name, alone or with a word like “Coastal” or “Inland” in front. The county codes NOAA also publishes have not been loaded for Mississippi yet; when they are, this page will count by code instead, and some counties' records will grow. NOAA names counted here: HANCOCK, NORTHERN HANCOCK COUNTY, SOUTHERN HANCOCK COUNTY. Zones named for something else, such as a mountain range or two counties at once, are left out: 0% of Mississippi's NOAA records.
- Counts last rebuilt from the source records on Sep 15, 2026.
