The National Weather Service says a weak tornado touched down in DeKalb County last week.

The EF-0 tornado happened at about 4:20 last Tuesday afternoon as a strong line of storms moved through DeKalb County prompting Severe Thunderstorm Warnings.

The National Weather Service says the tornado with peak winds of 80 miles an hour touched down northwest of Somonauk and was on the ground for 10 miles before lifting near Hinckley. It had a maximum width of 50 yards as it went through farm fields. A grain silo and power lines were damaged along its path.

About 20 minutes later, another EF-0 tornado touched down in Kane County near Lily Lake.

The weather service says the second tornado also had peak winds of 80 miles an hour and damaged trees and an outbuilding roof while it was on the ground for four miles.

The windy weather has continued since then.

DeKalb County was under a Wind Advisory on Sunday, and the weather service says a gust of 47 miles an hour was recorded at the DeKalb Taylor Municipal Airport shortly before 11 Sunday morning.
