The National Weather Service issued a flood warning Wednesday for portions of McHenry County near the Fox River.

The NWS issued a warning for areas including near the Fox River at the Algonquin Tailwater, the stretch of water immediately downstream of the dam. The warning will continue until further notice.

At 9:30 a.m. Wednesday, the river was 10.4 feet; the flood stage is 9.5 feet. The river will continue rising to almost 10.8 feet by Thursday afternoon and then begin falling, according to the NWS. Moderate flooding was reported at the Fox River in Algonquin, and minor flooding was reported along the river in McHenry.

The portion of the river between the dams in Algonquin and McHenry is closed. A debris advisory also remains in effect for the entire system, according to the Fox Waterway Agency.

The agency announced boaters are allowed to pull their boats at no wake speed but must call ahead to verify marinas are open and not sandbagged before proceeding. Boaters should maintain extreme caution because of fast river flows that could make it difficult for rescue crews to launch in emergencies.

The NWS recommends motorists avoid flooded roads. Although localized minor flooding could result, the NWS predicts that the threat of flash flooding still is low.

Amy Seeley, a meteorologist with the NWS in Romeoville, said about an inch of rain fell Wednesday. She said the next few days will be clear.

Ten days into October, Seeley said about 3.65 inches of rain has fallen, already beating the 3.15-inch monthly average for the Chicago area. She said there’s a 20 percent chance of rain Saturday night and a 30 percent chance Monday evening.

And don’t expect more days with temperatures in the 60s, 70s or 80s.

“We predict 40s and 50s through Oct. 17,” she said.
