Risk Overview

About Natural Disaster Risk in Iberia Parish, Louisiana

Iberia Parish faces severe national-level risk

Iberia Parish's composite risk score of 90.62 places it in the relatively-moderate category but ranks among the most hazard-exposed counties nationally. Extreme hurricane exposure (97.29) and elevated tornado risk (91.57) combine with substantial flooding (81.42) to create a severe multi-hazard environment. The parish sits in America's upper tier of disaster-prone locations.

Iberia ranks among Louisiana's highest-risk

At 90.62, Iberia Parish scores 28.2 points above Louisiana's state average of 62.37, making it one of the state's most hazardous regions. Only East Baton Rouge Parish (97.96) scores higher, with Iberia occupying a clear second-place position in statewide disaster risk. Residents face substantially greater threats than most Louisiana communities.

Second only to East Baton Rouge in risk

Iberia (90.62) trails only East Baton Rouge (97.96) but far outpaces every other nearby parish, including Iberville (73.73), East Feliciana (56.42), and Evangeline (75.92). Its hurricane exposure is among the state's highest and its tornado risk nearly rivals the highest-risk parishes. Iberia ranks unmistakably in Louisiana's most dangerous tier.

Hurricanes and tornadoes threaten relentlessly

Hurricanes dominate Iberia Parish's threat landscape at 97.29, nearly the highest possible score, while tornadoes add severe secondary risk at 91.57. Flooding (81.42) compounds these threats during tropical systems and heavy rainfall events. This trinity of hazards creates an exceptionally challenging disaster environment requiring year-round preparedness.

Comprehensive insurance is absolutely essential

Homeowners must carry full windstorm/hurricane insurance, flood insurance through NFIP (especially given coastal location), and maximum homeowners coverage to address tornado and wind damage. Hurricane shutters, roof reinforcement, and proper elevation for flood risk are critical physical investments. With Iberia's extreme exposure, maintaining 100% replacement-cost coverage is not optional—it's a survival necessity.

Risk Advisory: Iberia Parish

Risk Verdict

Iberia Parish's overall risk score at the 91th percentile nationally signals meaningful exposure to multiple natural hazard types. Comprehensive household preparedness — including reviewing insurance, maintaining emergency supplies, and knowing evacuation routes — is strongly recommended.

Hazard Breakdown

Hurricane risk is Iberia Parish's dominant natural hazard, ranked at the 97th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 92th percentile nationally. Additional tracked hazards include flood (81th percentile), earthquake (47th percentile), wildfire (29th percentile).

Preparedness Context

Iberia Parish ranks at the 97th percentile nationally for hurricane risk. For coastal counties, wind-resistant shutters or impact-rated windows represent the highest single structural investment for reducing property damage. Iberia Parish's tornado exposure at the 92th percentile nationally adds a hazard layer that can persist or intensify after hurricane-force winds have passed, particularly in low-lying inland areas. For extended post-storm outages common in Iberia Parish's hurricane zone, a portable generator (operated outdoors only) and a supply of non-perishable food for at least seven days provides meaningful household resilience.

Regional Context

Compared to other Louisiana counties, Iberia Parish runs 28.2 composite risk points higher than the state mean — reflecting above-average hazard concentration in this area.

How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Iberia Parish higher risk than average?
Iberia Parish's composite risk score of 91th percentile is above the Louisiana state average of 62th percentile. This elevated risk is driven by hurricane exposure (97th percentile), along with tornado and flooding risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
