The Red Cross is providing cots, bedding and hot meals at each of the shelter sites.
One hundred and fifty people were registered at the Miami site as of 5 p.m. Wednesday. At least 50 sought shelter in each of the three additional community shelters, according to local emergency management officials.
There is no charge for use of the shelter and meals are free.
Shelter sites include the following:
Miami - Assembly of God Church, 1815 E. Steve Owens Blvd.
Commerce - Southeast Baptist Church, 103 East B Street.
Picher - Picher Housing Authority, 100 Deville Creek.
Wyandotte - Community Center.
New! Welch - A shelter is now open at the Welch Community Center on 600 S. Curtis St.
Animal Shelter Open - The Ottawa County Animal Welfare Society is sheltering animals while owners seek safety in Red Cross shelters.
The site is set up at the Northeastern Oklahoma A&M College Equine Center on Rockdale Road in Miami.
Those dropping off animals are asked to bring a bag of food and, if dropping of a cat, provide cat litter and a litter box.
All animals must be picked up by 5 p.m. today due to an event scheduled at the arena.
Miami's water supply has not been compromised by the recent ice storm, according to city officials.
Water pressure is good and quality is not in question.
