Risk Overview
About Natural Disaster Risk in Assumption Parish, Louisiana
Assumption Parish faces moderate risk
Assumption Parish's composite risk score of 70.29 places it in the relatively low category, slightly above Louisiana's state average of 62.37. The parish has meaningful disaster exposure but ranks below several other Louisiana parishes.
Mid-range risk among Louisiana parishes
Assumption ranks in Louisiana's middle tier for disaster risk, neither among the safest nor the most exposed parishes. Hurricane risk (93.49) and flood risk (78.00) drive most of the parish's composite score.
Comparable to surrounding parishes
Assumption's 70.29 score sits between Avoyelles Parish (73.00) to the north and Acadia Parish (88.61) to the south. It's notably safer than Ascension Parish (92.14) to the northeast.
Hurricanes and floods are primary threats
Hurricane risk (93.49) and flood risk (78.00) dominate Assumption's hazard profile, reflecting the parish's coastal and low-lying geography. Tornado risk (67.37) adds a secondary concern, though at lower severity than neighboring parishes.
Flood and wind insurance are vital
Assumption residents living in flood-prone areas should carry federally backed flood insurance, while all property owners need windstorm protection. Elevating structures and maintaining natural water barriers provide additional protection beyond insurance.

Hazard Breakdown
Hurricane risk is Assumption Parish's dominant natural hazard, ranked at the 93th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 78th percentile nationally. Additional tracked hazards include tornado (67th percentile), earthquake (30th percentile), wildfire (4th percentile).
Preparedness Context
At the 93th percentile nationally for hurricane risk, Assumption Parish is in a zone where flood insurance matters beyond the primary wind risk: NFIP flood insurance requires a 30-day waiting period before taking effect, making off-season enrollment the correct timing. Flood at the 78th percentile nationally is Assumption Parish's secondary hazard, often intensified by the same weather systems that produce hurricane conditions. For Assumption Parish households, the hurricane preparedness calendar matters: flood insurance has a 30-day waiting period, wind-hardening retrofits take weeks to schedule, and evacuation route scouting is best done before a storm watch is issued.
Regional Context
A composite score 7.9 points above the Louisiana state average puts Assumption Parish in a higher-risk category than most counties in the state.
