OKLAHOMA CITY (AP) - Utilities are still working to restore power following a winter storm that brought ice, sleet and snow to Oklahoma last week.

Nearly 71,000 homes and businesses remained without electricity Tuesday.

The Oklahoma Department of Emergency Management reported that the majority of the power outages were in the southern part of the state. Utility officials have said it could be next week before service is restored.

Emergency management officials say the majority of outages, about 34,000, continue to be in the Oklahoma Association of Electric Cooperatives service areas. Other extensive outage areas are more than 20,000 Public Service Company of Oklahoma customers, more than 8,400 of which are in Lawton.

Altus' 9,300 customers make up the majority of the nearly 15,000 homes and businesses without power in the Oklahoma Municipal Power Authority service area.
