Risk Overview

About Natural Disaster Risk in Iberville Parish, Louisiana

Iberville Parish faces above-average national risk

Iberville Parish's composite risk score of 73.73 and relatively-low rating place it above typical national averages, indicating elevated but not extreme disaster exposure. Strong hurricane risk (94.41) and significant tornado exposure (77.42) drive most vulnerability, while moderate flooding (65.60) adds seasonal concern. The parish ranks in the upper-middle tier of American disaster risk.

Iberville scores above Louisiana average

At 73.73, Iberville Parish exceeds Louisiana's state average of 62.37 by 11.4 points, making it one of the state's higher-risk regions. While not as extreme as East Baton Rouge (97.96) or Iberia (90.62), Iberville clearly occupies the state's upper-risk tier. Residents face significantly steeper disaster threats than most Louisiana communities.

Moderate risk between high and low parishes

Iberville (73.73) sits comfortably below both East Baton Rouge (97.96) and Iberia (90.62) but substantially above Grant Parish (29.61) and Franklin Parish (35.91). Compared to East Feliciana (56.42), Iberville scores 17 points higher, reflecting greater hurricane and tornado exposure. The parish occupies a clear middle position within the regional risk spectrum.

Hurricanes and tornadoes drive most damage

Hurricanes pose the paramount threat at 94.41, while tornadoes follow closely at 77.42, making Iberville highly vulnerable to both tropical systems and severe thunderstorms. Flooding (65.60) represents a significant secondary concern during wet seasons and tropical events. Together, these three hazards account for nearly all of Iberville's disaster risk.

Prioritize windstorm and flood coverage

Homeowners must carry comprehensive windstorm/hurricane insurance and flood coverage through NFIP, given Iberville's dual exposure to tropical systems and seasonal flooding. Reinforced roof connections, proper grading for water drainage, and hurricane preparedness drills should be annual priorities. Review your replacement-cost coverage regularly to ensure it reflects current home values.

Risk Advisory: Iberville Parish

Risk Verdict

Iberville Parish's FEMA risk score places it at the 74th percentile nationally, indicating lower-than-typical exposure for a U.S. county. A moderate composite score often means one or two hazard categories are doing the heavy lifting — knowing which ones matters for preparation.

Hazard Breakdown

Hurricane risk is Iberville Parish's dominant natural hazard, ranked at the 94th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 77th percentile nationally. Additional tracked hazards include flood (66th percentile), earthquake (35th percentile), wildfire (6th percentile).

Preparedness Context

With hurricane ranked at the 94th percentile nationally, Iberville Parish sits in a zone where multi-day supply readiness matters: grid outages after landfalling storms can last one to three weeks in heavily affected areas. Tornado, the county's second-ranked hazard at the 77th percentile nationally, represents an additional preparedness consideration for Iberville Parish independent of hurricane season. Insurance gaps are the most common post-hurricane financial shock: standard homeowners policies typically exclude flood damage and may have a separate wind deductible. Iberville Parish households benefit from a pre-season insurance review confirming both wind and flood coverage.

Regional Context

The Louisiana county average is 11.4 composite points below Iberville Parish's score, a gap that reflects the county's elevated position in the state's hazard distribution.
