Tornadoes:

EF-1 Tornado in Manhattan, IL

Tornado - Manhattan, IL Will County Date 26 June 2018 Time (Local) 6:54-6:59 CDT EF Rating 1 Est. Peak Winds 95 mph Path Length 1.13 miles Max Width 100 yards Injuries/Deaths None Summary: Damage was first observed at a farm along Bruns Road. Two large trees lost limbs or portions of their trunk and numerous smaller branches were broken. The resident reported seeing a mass of wind and clouds upstream from this location but not a funnel. There was no damage observed in the crops upstream of this location, at least from what could be seen from the ground. There was debris in the field north of the farm, but no other damage was visible until the tornado entered Manhattan near the park. Damage in Manhattan consisted of numerous snapped branches of various size and at least two large (> 1ft diameter) trunks snapped. Damage in the park was about 100 yards wide. Several buildings in town received just minor damage, but the post office lost a portion of its roof covering, and a building next door had broken windows as well as shingle and roof damage.  The tornado dissipated near Prairie Street as it exited downtown. No damage was seen in the tree line north of Prairie Street. Track Map Downloadable KMZ File

• Two other very brief tornadoes were observed and filmed by trained spotters. 
  • One was in Kane County, 4 miles SSE of Maple Park, IL.  A video showed a brief surface touchdown that kicked up some water in a field. The tornado only lasted a few seconds and produced no damage, so it was not surveyed, nor has an exact position been established.
  • The other was in Will County southeast of Manhattan, somewhere in the area between Wilton Center and the Green Garden Country Club.  No damage was reported with this tornado but this area was surveyed by the National Weather Service, and no damage was observed.  The exact location where spotter video indicated a touch down has not been established.

The Enhanced Fujita (EF) Scale classifies tornadoes into the following categories:

EF0 Weak 65-85 mph	EF1 Moderate 86-110 mph	EF2 Significant 111-135 mph	EF3 Severe 136-165 mph	EF4 Extreme 166-200 mph	EF5 Catastrophic 200+ mph
