Risk Overview

About Natural Disaster Risk in Washington Parish, Louisiana

Washington ranks among nation's riskiest

With a composite risk score of 85.53, Washington Parish faces relatively moderate risk that exceeds most American counties. The parish's hurricane risk score of 95.91 places it among the most vulnerable communities in the nation to major tropical storms.

Louisiana's highest-risk parish overall

Washington Parish leads all 64 Louisiana parishes with a composite risk score of 85.53, far exceeding the state average of 62.37. The parish sits at the intersection of multiple hazard zones—coastal hurricane exposure, significant flood vulnerability, and elevated wildfire and tornado risk.

Significantly riskier than east-bank peers

Washington's risk profile substantially exceeds neighboring St. Tammany and St. Helena parishes, primarily due to elevated hurricane (95.91) and wildfire (80.03) scores. The parish's eastern location exposes it to Gulf storm surge paths that neighboring parishes experience less intensely.

Hurricanes and wildfires pose dual threats

Washington faces critical hurricane risk (95.91) and elevated wildfire risk (80.03), creating complex preparation challenges across two distinct seasons. Flood risk of 78.98 compounds exposure during storm events, and tornado risk of 71.63 requires year-round vigilance.

Multi-layered insurance strategy vital

Washington residents need comprehensive hurricane preparation including structural reinforcement and separate flood insurance, given scores exceeding 78 for both hazards. Review your homeowners policy annually, maintain emergency supplies, and create an evacuation plan—this parish faces the state's most complex disaster landscape.

Risk Verdict

At the 86th percentile nationally, Washington Parish sits in the upper half of U.S. counties for natural disaster exposure. At this risk level, having a documented household preparedness plan — not just awareness — is the meaningful next step for Washington Parish residents.

Hazard Breakdown

Hurricane risk is Washington Parish's dominant natural hazard, ranked at the 96th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 80th percentile nationally. Additional tracked hazards include flood (79th percentile), tornado (72th percentile), earthquake (55th percentile).

Preparedness Context

With hurricane ranked at the 96th percentile nationally, Washington 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. Washington Parish's wildfire exposure at the 80th percentile nationally adds a hazard layer that can persist or intensify after hurricane-force winds have passed, particularly in low-lying inland areas. Insurance gaps are the most common post-hurricane financial shock: standard homeowners policies typically exclude flood damage and may have a separate wind deductible. Washington Parish households benefit from a pre-season insurance review confirming both wind and flood coverage.

Regional Context

The Louisiana county average is 23.2 composite points below Washington Parish's score, a gap that reflects the county's elevated position in the state's hazard distribution.

Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Washington Parish higher risk than average?
Washington Parish's composite risk score of 86th percentile is above the Louisiana state average of 62th percentile.
