Event Narrative The tornado entered LaSalle County from Putnam County, approximately 3 miles northeast of the town of Standard, producing F0 intensity damage in a wooded area southwest of Peru. As the tornado continued northeast, F2 intensity damage was done to several homes in a subdivision near the intersection of East 250th and 2569th Roads. Several roofs were blown off homes along with damage to external walls. Significant tree damage was done as well. Path width was estimated at 50 yards at this location. The tornado then continued northeast, crossing the Illinois River twice as it moved toward the town of Utica, downing a steel high tension tower on the north bank of the river, immediately west of Illinois 251. The tornado moved into the southwest side of Utica where it was F0 intensity. Homes along Washington Street only had tree and minor roof damage. A church steeple was damaged on Division between Johnson and Washington. Roofs and trees were more severely damaged on the south side of Johnson Street. The tornado rapidly increased to F3 intensity on the north side of Johnson Street where one home had its roof taken off and north walls blown out. A machinery building was completely destroyed on the south side of the canal and a semi-tractor trailer was blown into the canal. A large grain bin was blown across the canal and flattened. The tornado then moved north of the canal into the heart of town where several homes were severely damaged, garages were destroyed and brick buildings collapsed. Eight people died and seven were rescued from the basement of a turn of the century sandstone building at Clark and Church Streets. The tornado was approximately 250 yards wide at this point. On the east edge of the vortex along Mill Street, in downtown, buildings suffered damage to facades, roofs and windows. East of Mill Street there was damage to trees and minor roof damage. In the northeast section of town a mobile home was overturned on Grove, just east of Mill Street. The vortex crossed the railroad tracks and apparently dissipated on a steep bluff on the northeast side of town. At the top of the hill there were some trees and limbs down and some debris deposited.
