Tornado Risk in Jefferson Davis County, MS
Jefferson Davis County's tornado history, by the numbers
49 tornado tracks have crossed Jefferson Davis County since 1961 by NOAA's count, roughly one every 1.6 years - the High band on this site's scale. That is the 87th percentile nationally for tornado frequency. Among 82 Mississippi counties in this dataset, Jefferson Davis County ranks 29 for how often a tornado touches down.
The number that matters more than frequency
Yes. Jefferson Davis County has recorded 3 EF4 or EF5 tornados - the strength FEMA's own safe-room guidance is built around, because a standard code-built house is not expected to survive those winds without a hardened room. A county can be lower-frequency overall and still carry this history.
Shelter and safe-room economics
A storm shelter or in-residence safe room typically runs $2,890-$13,280 nationally (around $7,645 typical). Mississippi's Mississippi Emergency Management Agency's Safe Room Program covers 75% of an approved project, up to $3,500 - bringing a typical job down to roughly $722.5-$9,780 out of pocket, when the program is currently funded.
Power after the storm, not just shelter during it
Tornado outbreaks routinely knock out power across Mississippi 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
Mississippi 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 Jefferson Davis County policy rather than assuming it is included.
What Jefferson Davis County's figure does not tell you
Jefferson Davis County's figure is county-wide, not address-specific. Jefferson Davis County covers about 408 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. NOAA also documents that older records undercount weaker tornadoes from before Doppler radar became standard. Jefferson Davis County has about 11,059 residents.
