How Likely Is a Tornado in Plaquemines Parish, LA?
Plaquemines Parish, LA: what NOAA's tornado record says
Plaquemines Parish has recorded 37 tornado touches in NOAA's 76-year database, a rate of roughly one every 2.1 years - our Elevated band. Put another way: Plaquemines Parish sees more tornado activity than 77% of US counties. Among 64 Louisiana counties in this dataset, Plaquemines Parish ranks 35 for how often a tornado touches down.
Beyond the frequency band: violent history
31 weak and 4 significant tornadoes make up Plaquemines Parish's 37-track record - none violent. NOAA has never logged an EF4 or EF5 crossing this county.
The dollar figure Plaquemines Parish's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Louisiana has no state rebate program confirmed here; FEMA's underlying 75% cost-share exists nationwide, but applying through a state program is what usually makes it real, and none was found for Louisiana this pass.
What a direct hit isn't required for
Tornado outbreaks routinely knock out power across Louisiana for days, separately from any single house getting hit. A portable battery bank keeps a fridge, phone chargers and a radio running through that gap - cheaper and faster to set up than a generator.
Wind damage may need its own endorsement
Louisiana is one of a handful of states where insurers can write wind/hail damage out of a standard homeowners policy - tornado damage may not be fully covered without a separate wind endorsement. Worth confirming directly on a Plaquemines Parish policy rather than assuming it is included.
What this number is, and is not
One caveat before relying on Plaquemines Parish's number: it is county-wide, and it covers about 781 square miles, so a single touch counts the same as one in a county a fraction of that size. Weaker pre-1990s tornadoes are also documented as undercounted in NOAA's own record. Plaquemines Parish has about 22,289 residents.
