Editor's note: This story originally reported that sirens would turn on in Jenks due to flooding. After posting on Facebook that announcement, city officials said that plan was not carried out. 

Tulsa Mayor G.T. Bynum on Wednesday afternoon said Tulsa police are encouraging people living near the Arkansas River to evacuate as the river approaches moderate flood stage with more rain in the forecast.

"Tulsa police are already visiting specific neighborhoods at risk and encouraging evacuation," he said in a tweet, without elaborating on specific areas.

"These are in the immediate vicinity of the river."

Tulsa Police Sgt. Shane Tuell said the city is not releasing the areas being evacuated to prevent looting.

"We don't want bad guys to know where the areas are that are about to have vacant houses," Tuell said.

The Police Department is going house to house in neighborhoods where residents need to evacuate immediately, Tuell said, adding that the city will provide specifics on the evacuations as more details of possible flooding become known.

"When we are able to get better mapping details and updated mapping information that will give us a better sense of where to deploy our manpower and to effectively warn the citizens," Tuell said.

River Spirit Casino closed at 2 p.m.

The closure required removal of all hotel guests, visitors and vehicles.

“The elevation of the Resort property was built to sustain a 100-year-flood; however, the impact of the water levels to access the property, and to best protect our guests and employees, requires us to completely close the property until further notice,” CEO Pat Crofts said in a news release.

Hotel guests are being relocated, and planned guests are being contacted for rescheduling, according to the release.

Cherokee Nation closed its casino in Fort Gibson at 9 p.m. Tuesday, according to spokeswoman Amanda Clinton. She said the tribe was made aware of an emergency release at Keystone Dam early Tuesday and made plans to close due to the possibility of flooding on Oklahoma 62. The casino will remain closed until the flooding emergency is over. Employees of the casino are being assigned to work at other properties during the closure, Clinton said.
