St. Martin Parish, LA Tornado Risk & Storm Shelter Cost
St. Martin Parish's tornado history, by the numbers

St. Martin Parish's EF4-5 history
St. Martin Parish's record has no EF4-5 tornado - its 26 tracks split 17 weak and 7 significant. That does not rule one out in the future, only that none has been recorded since 1950.
What a storm shelter costs near St. Martin Parish
For a St. Martin Parish homeowner, budget $2,890-$13,280 for a shelter or safe room ($7,645 typical) - this pass found no Louisiana-specific rebate on top of FEMA's underlying 75% national cost-share program.
The outage nobody plans for
The storm that misses St. Martin Parish outright can still take its power out - outbreak-scale outages across Louisiana are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
Check your coverage, not just your risk
Because Louisiana allows wind/hail exclusions on standard homeowners policies, a St. Martin Parish homeowner should confirm tornado wind damage is actually covered, not assume it - a separate endorsement is common here.
Read this before you rely on it
This is a county-level figure, not a per-address probability. St. Martin Parish covers about 738 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. Pre-radar-era records (before the 1990s) are also documented by NOAA as undercounting weaker tornadoes in sparsely-instrumented areas. St. Martin Parish has about 51,218 residents.
