Six tornadoes were produced during the late afternoon/early evening of January 7, 1989.  The most significant tornado of the day hit the small town of Allendale, IL in Wabash County.  Per the Storm Data Narrative from January 1989, “much of the town was obliterated.”  

The tornado developed about 4 miles SW of Allendale or 1 mile NW of Patton.  It moved northeast through Allendale and into the rural areas of Wabash County.  It then crossed the Wabash River into Indiana moving into Knox County.  The tornado dissipated 5 miles SE of Vincennes or 1.5 miles SW of Frichton.  There is a discrepancy on the path length.  The SPC has a length of 19 miles.  The Storm Data Narrative has a length of 22 miles (7 in Illinois and 15 in Indiana).  

Per the NWS survey, the tornado began at F2 intensisty and then intensified to lower end F4 about 1/2 mile SW of Allendale.  It reached maximum F4 intensity in ther southern part of Allendale.  It then dropped to F2 status by the time it hit the Wabash River and then down to F1 towas the end of its path.

Some of the damage reported:

  • 2 farm houses were first damaged ~ 1 mile SW of Allendale.
  • 4 houses were completely swept away from their foundations at the far SW corner of town.
  • Houses over a roughly 7 block area on top of a hill in the main part of town were leveled.
  • City Hall on the north side of Main Street lost most of its walls.
  • The Post Office across the street from City Hall lost part of its roof.
  • An occupied mobile home SW of the Post Office was flipped onto an automobile and then onto a second occupied mobile home.  All occupants survived.
  • Portion of a church east of the Post Office remained standing while the concrete block firehouse further east was completely destroyed.
  • The brick Allendale School was extensively damaged and the upper floor was removed from the southern half of the school.

From the January 1989 Storm Data Publication:

  • The population of Allendale at the time was about 600 people
  • 10 businesses, 47 homes and 54 vehicles were destroyed
  • It was found later during an aerial survey of the damage that the tornado left a number of swath marks in farm fields just prior to entering the town, indication that the devastating tornado was composed of multiple suction vortices, numerous miniature but very intense tornadoes rotating about a common center
