Jackson County’s 80 recorded tornadoes include deadly storms in February and May. For a shelter quote, ask a local installer to assess your chosen spot and handle any permit paperwork.

Tornadoes outside the usual season

Three tornadoes in the county’s record stand out:

  • May 11, 1982, F3: tied for the deadliest. It killed 2 people and injured 18 on a 10-mile path that stayed in Jackson County.
  • February 22, 1975, F2: it also killed 2 people and injured 8, on a 5.2-mile path inside the county.
  • November 7, 2011, EF4: the strongest tornado in the record. No deaths or injuries are listed. It also touched Tillman County.

Ratings show the worst damage anywhere on a tornado’s path. Deaths and injuries also count the whole path.

The 2016–2025 total is 9 tornadoes; none is listed as EF3 or stronger. The county’s 2021–2026 draft hazard plan also lists an EF3 near Elmer on May 16, 2015, and an EF0 at Altus on May 9, 2013. The plan says every part of the county is equally at risk, and it rates future tornadoes as “Likely”.

A county list of private shelters

The Jackson County draft hazard plan for 2021–2026 includes a project to locate and map private storm shelters inside the county’s towns. The goal is a plan to get people out of a shelter after a storm if needed. The plan marks the database as complete and continuously updated, as owners report new shelters.

In Altus, the Fire Department has run a free, voluntary shelter registry since 1999. The city uses the information only if a storm causes structural damage. Details are on storm shelters in Altus.

Clay that reaches the surface

The survey puts 28.4% of Jackson County’s mapped land in the high or very high shrink-swell classes. These ratings describe soil expansion when wet and shrinkage as it dries. The surface layer has a high or very high rating on 16.4% of mapped land. The largest such area is Hollister silty clay loam, 74,262 acres on 0–1% slopes. If you plan an in-ground shelter, ask the installer how it handles this clay at your spot. The county map is not a test of your own lot.

If cracks or sticking doors are the concern, see foundation repair in Altus. Published shelter prices are on storm shelter costs in Oklahoma.

Asking for a free quote

Request a free quote and ask the installer to see the spot before setting a price. A written quote should show:

  • the shelter and its installation
  • any city permit, with its fee
  • digging and dirt hauling, as separate lines

Also ask whether the installer reports the new shelter to the local registry for you.
