When was the last damaging storm in Miller County?

The most recent record with damage, injuries or deaths is the July 8, 2024 tornado.

An EF-1 tornado with estimated maximum winds near 95 mph touched down along the Red River just north of its confluence with the Sulphur River in Southeast Miller County south of County Road 12, and initially moved in a generally northerly direction along County Road 8. Most of the damage consisted of uprooted trees and downed limbs, but a metal barn near the tornado's start point sustained the loss of a few metal roof panels. The tornado then made a turn to the northwest and continued to snap trees as it crossed Miller County 9, Interstate 49, and Highway 71. The tornado tracked between Miller County 7 and Highway 71 just south of Fouke, snapping and uprooting additional trees. As the tornado began to occlude, it turned to the west and moved along Miller County 24 damaging additional trees before lifting just west of the intersection of Miller County 7 and 24.
