1002 PM     Tornado          1 ENE Rolla             37.96N 91.75W
07/09/2026                   Phelps             MO   NWS Storm Survey

            An EF0 tornado with peak winds of 80 to 85
            mph began along Homelife Plaza in Rolla and
            travelled south before lifting near Soest
            Road. Tree and building debris was laying in
            convergent patterns. Additional limbs were
            downed south of Soest Road, however it could
            not be determined as tornadic from that
            point on due to the lack of convergent
            damage. The tornado was on the ground for a
            total of 0.7 miles with a width of 200 yards
            and caused damage to trees and the roofs of
            several businesses.
