What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

The tornado began in Bridgeton on Pennridge Drive, just northeast of St. Charles Rock Road. A skating rink in this location suffered EF-1 roof damage. The tornado moved northeast causing sporadic EF-0 and EF-1 tree damage for about 3 miles crossing Highway 370 in the process. The tornado intensified to EF-2 strength in Hazelwood near Woodcrest Lane where the roof was torn off a home. The tornado was also at its maximum width at this location reaching 500 yards wide. Along Teson Road, north of Howdershell Road, 10 apartment buildings were damaged with 5 buildings losing portions of their roofs. The tornado then turned a bit to the east and caused EF-2 damage at Lynn Haven Lane and Howdershell Road. Two homes at this location lost most of their roofs. Also, across the street on the north side of Howdershell Road a strip mall had small portions of the roof removed, as well as glass windows and doors shattered. Tree damage, EF-0 to EF-1 strength, occurred along Lamplight Lane, Coach Light Lane, Caposele Lane, and Gerardini Drive. Several homes on these streets suffered roof damage from falling trees and large tree limbs. The area from Lynn Haven Lane to Gerardini Drive had the highest concentration of damage. As the tornado moved east northeast into Florissant sporadic EF-0 to EF-1 tree damage occurred to just east of St. Ferdinand Park along Beverly Drive. Also, just south of St. Ferdinand Park, another strip mall at the intersection of Lindbergh Boulevard and St. Jean Street sustained minor roof damage. The tornado moved very fast, covering 6.75 miles in about 5 minutes. Sporadic thunderstorm wind gust damage, mainly tress uprooted or large limbs downed, was noted north and south of the tornado track. Several business signs were also damaged along Lindbergh Blvd. in Florissant. Two people sustained minor injuries. One had a broken leg and another just had some scrapes and bruises. Almost 400 structures sustained some kind of damage. Fifty five of these structures were either destroyed or sustained significant damage. The tornado was rated EF-2 overall.
