SURVEY_SUMMARY: The first area of significant damage in the EF2
range was in the area around the La Salle County Nursing Home and
La Salle County Highway Department, with lighter damage upstream
from this location. The tornado continued into Naplate and
produced widespread EF2 damage to numerous homes. EF3 damage also
was identified in two locations, the first where a home was
lifted off its foundation and left with only its interior walls
intact, and the second at the Pilkington Glass plant where one
section of the factory was completely destroyed. The tornado then
crossed the Illinois River and moved through the south side of
Ottawa, producing an 800 yard wide path of EF1 damage to trees
and homes. The tornado then crossed the Illinois River again and
continued to produce EF1 and EF0 damage as it exited Ottawa,
finally dissipating in the area northwest of Marseilles.
