Heavy rains predicted for Thursday could dump about an inch of precipitation on Marshall County but it’s not expected to cause the Yellow River in Plymouth to break its banks.
The National Weather Service is forecasting chances for rain through Wednesday before there is a high likelihood of precipitation Wednesday night and through Thursday. As much as 1 inch of rain is possible, with amounts possibly higher north of U.S. 30.
The weather service is also calling for a potential wintry mix Thursday night that could cause travel issues Friday morning.
With the new rainfall, the Yellow River is now expected to rise to slightly over 12 feet, still below the waterway’s 13-foot flood stage, according to the NWS.
Late Tuesday, the Yellow River was at about 11.5 feet, above the river’s action stage of 11 feet. The weather service defines the action stage as being when water reaches – or comes close to reaching – the river’s banks and accumulated rainfall can inundate low-lying areas.
After cresting at about 17.65 feet late Thursday – a record level – the Yellow River in Plymouth dropped below the 13-foot flood stage early Tuesday, according to weather service data. The river finally dropped below major flood stage – 15 feet – Sunday afternoon, according to the NWS.
The NWS extended a flood warning for the Yellow River in Knox through Thursday evening. The river was at about 10.5 feet early Wednesday, above the waterway’s flood stage of 10 feet. However, the river is expected to drop below flood stage Wednesday evening.
The predicted rainfall isn’t expected to cause additional flooding. However, the Yellow River at Knox is expected to remain at action stage through early next week, according to the NWS. The river crested at 13.75 Saturday evening.
The Tippecanoe River at Ora will remain under a flood warning until further notice, according to the weather service.
The Tippecanoe River was at 13.75 late Tuesday, well above the river’s 12-foot flood stage. The waterway is expected to stay above flood stage through the weekend.
The Tippecanoe River at Ora crested at about 15.6 feet Friday morning, just short of the record of 15.7 feet set in 2009.
