MAZON — A weak tornado touched down near Reed Road and Higgins Road near Mazon Tuesday night and caused minor damage, according to the National Weather Service in Chicago.
With wind speeds of about 85 miles per hour, the tornado had a path two miles long and 30 yards wide.
It blew down a power pole near Reed Road and Higgins Road and three more by Campbell Road, north of Spring Road, the National Weather Service said.
The tornado also tore the doors off a building and apparently carried a trampoline from a backyard before dissipating west of Coal City.
Jim Allsop, a meteorologist with the National Weather Service’s Chicago office in Romeoville, said the tornado was low intensity.
“As far as tornadoes go, that’s about as weak as they come,” Allsop said.
Allsop said he drove to the area to examine the effects of the storm and, other than the downed poles, did not observe much damage.
The tornado was an F-0 classification, according to Grundy County Emergency Management Director
Jim Lutz, denoting it as the mildest possible tornado.
“It’s relatively small in the tornado world,” Lutz said. “Luckily it was in an open area and the damage it caused wasn’t too extensive.”
Grundy County Sheriff Kevin Callahan did not believe the department had received any calls for assistance, Callahan said.
Allsop said radar signals suggested the tornado could have passed over La Salle County, but he went to Seneca and did not observe any damage that would indicate it had landed there.
STORMY WEATHER CONTINUES
The tornado was part of a week of stormy weather across the region.
On Wednesday, Marseilles Mayor Patti Smith issued an emergency declaration for the city, with concerns of potential flooding due to projected weather through the week into the weekend.
On Thursday, La Salle County was put under flood warning for the Illinois River until Monday afternoon. Minor flooding has already begun, according to the National Weather Service.
Marseilles, which is in La Salle County, is still recovering from the severe flooding that forced mass evacuations in April.
Grundy County was put under a severe thunderstorm warning Thursday afternoon, as were La Salle, Will, Cook and Lake.
