A handful of residents in Missouri’s capital city and some businesses have been ordered to leave as the Missouri River rises.

Jefferson City issued a mandatory evacuation order Wednesday for residents and businesses on the north side of the river. The capitol building, state penitentiary and nearly all of the city’s homes are on the south side of the river.

Residents of several communities in Oklahoma and Kansas also have been urged to evacuate as rivers and streams rise.

Jefferson City police Lt. Dave Williams estimated that only about five to 10 homes are in the area that’s under a mandatory evacuation.

As a precaution, the Missouri National Guard also moved four helicopters out of the city’s airport, which also is on the north side of the river. And a Memorial Day weekend airshow was canceled.

More Oklahoma residents are being encouraged to evacuate because of expected flooding that has also prompted concerns in Missouri and Kansas.

Authorities on Wednesday encouraged people living along the Arkansas River in the Tulsa suburb of Bixby and low-lying areas near creeks both north and south of Okmulgee, about 35 miles south of Tulsa. to leave their homes.

Residents in the Tulsa suburb of Sand Springs; Fort Gibson, about 50 miles southwest of Tulsa; and Webbers Falls, some 70 miles southeast of Tulsa, were advised earlier to evacuate because of flooding forecast on the Arkansas River.

Residents along the Cimarron River were evacuating as the riverbank eroded beneath their homes about 34 miles north of Oklahoma City.

One unoccupied home rolled off the river bank and into the Cimarron River on Tuesday. Authorities say parts of others ae hanging over the riverbank and are threatened with collapsing.
