Residents along the Fox River should be prepared for major flooding, the National Weather Service said, as the area readies for another wet day.
Late Wednesday night, the weather service upgraded the level at which the Fox River will crest from moderate to major flooding.
The weather service anticipates Wednesday’s severe weather will continue today with damaging thunderstorm winds and hail larger than one inch in diameter.
The threat for isolated tornadoes also remains.
On Wednesday, the National Weather Service issued a flood warning for the Fox River at the Algonquin Tailwater. By Wednesday afternoon, the water level was at 10.21 feet. Rounds of heavy rain-producing thunderstorms also are expected today, which will continue the flooding threat.
“There could be flooding not just near creeks, streams and rivers, but we could also see some pretty significant flooding in low-lying areas,” said Gino Izzi, meteorologist with the National Weather Service.
The area’s recorded rainfall was as high as 2.26 inches in Cary, 2.25 inches in Algonquin, 2.21 inches in McHenry and 1.94 inches in Woodstock, said a Weather Service meteorologist.
An aerial flood warning remains in effect through noon today as thunderstorms are expected to produce rainfall in excess of 4 inches in some portions of northern Illinois and northwestern Indiana.
The Fox Waterway Agency closed the entire Fox River and Chain O’ Lakes system from Algonquin to the state line. Residents along waterways were encouraged to sandbag their properties.
In Algonquin, sandbags will be available for residents at the Algonquin Wastewater Treatment Facility, 125 Willbrandt St.
The National Weather Service was forecasting water levels to be 2 feet above flood stage at the Fox River in Algonquin, and drivers should take extra caution when going through low-lying areas, Izzi said.
