About 300 people remained displaced by flooding Monday afternoon as a result of heavy rainfall that occurred earlier in the day in Riley County, including the Manhattan area, the Riley County Police Department reported.

An emergency evacuation shelter held been put in place at Pottorf Hall at the county fairgrounds and efforts were under way to set up a second shelter, the department said on its Facebook page.

"The number of homes affected is not known at this time," the the post said. "An assessment will be done later today to determine that number."

No fatalities or serious injuries had been reported by early Saturday afternoon, according to the police Facebook page.

It indicated the Manhattan Fire Department by boat, dump truck or in person had removed 60 people from Manhattan's Redbud neighborhood, 50 people and 20 pets from the Gardenway neighborhood, 26 people and four pets from the Village/Whitetail neighborhood and 16 people from Highland Ridge.

The Riley County Police Facebook page said Manhattan and Riley County officials were notified about 4:30 a.m. Monday that water in Wildcat Creek was rising rapidly after heavy rainfall at Keats, an unincorporated community about five miles west of Manhattan.

"The (Army) Corps of Engineers reports rainfall around 8.9 inches and around 3-4 inches in Riley," the post said. "That water then came down Wildcat Creek. Roads were blocked off and residents were notified at that time to evacuate if they lived in the areas near the flooded roadways."

Power outages continued to affect more than 700 homes and businesses early Monday afternoon in the Manhattan area, according to the Westar power outage map.

The police department reported earlier Monday afternoon that the water was receding in some areas but water levels were rising in others. Police warned the public to not go through areas of high water.

Authorities were waiting for water to recede from two bridges that had been closed as a result of the flooding so inspectors could determine whether they were safe, Manhattan city manager Ron Fehr said in a medic briefing early Monday afternoon. The briefing was broadcast live on the police department Facebook page.

Flash flood warnings had also been issued Monday for portions of Marshall, Pottawatomie and Geary counties.

An area north of Manhattan received 9.13 inches of rain inches of rain. Radar estimates projected other areas in north-central and northeast Kansas received about 10 inches of rain.

Meteorologist Brandon Drake, of the National Weather Service office in Topeka, said reports of flooding were coming in throughout Monday morning.

Among areas with the most severe flooding was Keats, located along Wildcat Creek about five miles west of Manhattan. Residents of that area were being evacuated before sunrise Monday.

Drake said the rain fell about 10 hours straight in places, starting Sunday evening and continuing until around 8 a.m. Monday.

The heavy rainfall "tapered off" just east of Manhattan, near St. George, Drake said. Areas east of that location didn't receive the heavy rains on Monday.

More rainfall is expected over the next few days in north-central and northeast Kansas, as warm, moist air continues to make its way into the area from the Gulf of Mexico.

Earlier Monday, the National Weather Service issued several flash flood warnings and was monitoring the levels of creeks and rivers in the area.

A Flash Flood Warning was issued around 5:50 a.m. for southern Geary and south-central Riley counties. The warning was to be in effect until 8:45 a.m., as heavy rain was falling in the area. The weather service said 2 to 4 inches of rain already had been reported in the area.

Some locations expected to have flooding included Junction City, Ogden, rural areas of Geary County and Grandview Plaza. The Flash Flood Warning included Interstate 70 between mile markers 295 and 314.

Meanwhile, evacuations were taking place a few miles to the east.

Another Flash Flood Warning was in effect until 9 a.m. Monday for southeastern Marshall, northwestern Pottawatomie and central Riley counties, according to the National Weather Service.

Excessive rainfall over the area could cause mudslides near steep terrain, the weather service said. The mudslide can consist of rock, mud, vegetation and other loose materials.

The weather service said locations expected to experience flooding included Manhattan, Blaine, Ogden, Riley, Frankfort, Leonardville, Olsburg, Randolph, Keats and Tuttle Creek Lake.
