On this day in 1989: Straight-line wind damage and a few isolated tornadoes occurred. The vast majority of the damage was in the form of downed trees and power lines. One storm spawned a tornado that touched down near Clinton, LA (East Feliciana Parish). The tornado moved due east carving out a roughly 3 mile path of destruction. The F2 tornado caused no fatalities nor injuries but did produce an estimated $250K in damage.
