Forecasters are warning of worsening floods after heavy rain closed sections of Kansas highways 87 and 99 in Marshall County late Wednesday, pushing the expected crest of the Big Blue River near Blue Rapids to 41.5 feet by early Sunday afternoon.

As the swollen river empties into Tuttle Creek Lake above Manhattan, the National Weather Service is also projecting minor weekend flooding along the Missouri River, with crests expected to reach 21.2 feet in Leavenworth on Saturday and top the 25-foot flood stage near Parkville, Missouri, on Sunday.

With the Big Blue having already surpassed its 26-foot flood stage and more rain forecast for Thursday, officials caution that downstream reservoir releases and river forecasts will likely be revised further.
