The Fox River in Algonquin is estimated to rise just below its flood level and stay there throughout the weekend, National Weather Service meteorologist Charles Mott said.
The portion of the river, which has a flood stage of 9.5 feet, is expected to rise to 9.4 feet by 6 a.m. Friday morning.
The service issued a flood advisory Thursday afternoon. Rainfall of one- to three-quarters of an inch in the past 24 hours on top of saturated soil caused water levels to rise, according to the weather service.
However, Mott said, the National Weather Service is not expecting that section to reach flood stage.
Many were without power Thursday, too, with equipment problems, downed power lines and severe weather listed as some of the causes for the outages.
ComEd’s outage map showed Thursday morning that more than 900 people near Wonder Lake were without power.
A few hundred customers also were out of power near Johnsburg and McHenry, and about 100 in Harvard did not have power. More than 700 customers were without power Thursday morning in the Lakewood area.
As of 3 p.m. Thursday, more than 170 people in the Johnsburg area, more than 300 people in Wonder Lake and more than 350 people south of Bull Valley still were without power.
Lee Schuppert – who lives north of Crystal Lake near Walkup and Crystal Springs roads – said his home lost power about 2 p.m. Thursday.
ComEd listed the reason for the outage in his neighborhood as “severe weather,” and Schuppert said he could see ice coating the power lines.
“We did not have a generator, unfortunately,” Schuppert said. “We probably will the next time.”
