About Natural Disaster Risk in St. Landry Parish, Louisiana

St. Landry ranks above national average

With a composite risk score of 88.20, St. Landry Parish faces significantly higher natural disaster risk than the typical U.S. county. This "Relatively Moderate" rating reflects the parish's exposure to multiple hazard types, particularly tornadoes and hurricanes that regularly threaten the region.

Well above Louisiana's typical risk

St. Landry's 88.20 score towers 41% above Louisiana's state average of 62.37, placing it among the riskier parishes statewide. The parish experiences compound threats that most of the state does not face at comparable intensity levels.

Similar risk to southern Louisiana parishes

St. Landry's risk profile closely mirrors that of St. Martin Parish (87.28) and St. Mary Parish (88.93), three southern parishes sharing comparable tornado and hurricane exposure. All three face substantially higher risk than Tensas Parish (14.50) in northeast Louisiana.

Tornadoes and hurricanes dominate

Tornado risk scores an exceptionally high 94.15, while hurricane risk reaches 92.24—making these the two primary threats residents must prepare for. Flooding also registers as significant at 87.44, creating a triple threat during severe weather events.

Bundle coverage for multiple threats

St. Landry residents should secure comprehensive homeowners insurance that includes coverage for wind damage (hurricanes and tornadoes) and flood damage, which standard policies exclude. A safe room or storm shelter adds crucial protection given the parish's extreme tornado risk of 94.15.
