Thunderstorms could dump five inches of rain on DeKalb County today after a faster-moving storm downed trees and power lines Monday. The county remains under a flash flood watch until 7 a.m. Wednesday, according to the National Weather Service.
Somonauk Street at Chauncey Street was closed Monday evening as Sycamore public works crews removed a tree in the road there. Meanwhile, DeKalb fire crews were responding to trees and power lines that were knocked down across the city north of Route 38, DeKalb Fire Chief Eric Hicks said.
The southern part of the county, including Sandwich, experienced more serious damage, Northern Illinois University Meteorologist Gilbert Sebenste said. Winds of 75 mph were reported at Route 47 and Interstate 88 in Kane County, and gusts of 65 mph were reported in Steward in Lee County, Sebenste said.
Southern DeKalb County was under a tornado warning between 5 p.m. and 5:30 p.m. Monday.
About 3,700 customers lost power, with about 2,000 customers without power by 7:30 p.m. Monday, ComEd spokesman Paul Callighan said. Most of them were south of Interstate 88.
Sebenste saw power lines and poles shake as the storm passed him while he was driving on Bethany Road just east of First Street in DeKalb.
“I was trying to outrun the storms in my car, and it overtook me,” Sebenste said. “I saw small trees fall in front my car.”
The ground is saturated after more than 3 inches of rain fell over the weekend, so strong rain today could cause flash floods, Sebenste said.
“Our drought is over,” he said, laughing.
