State officials say the number of Oklahoma homes and businesses without power had dropped below 100,000 as of Sunday afternoon.

The Oklahoma Corporation Commission said Sunday that 92,460 customers of electric utilities were still without power due to the winter storm that hit the state Thursday.

Authorities said the storm was linked to four deaths in the state. An Ada woman died when a propane tank exploded, a Pontotoc man using a wood-burning stove died in a house fire, a Holdenville driver died in a weather-related accident and a Geary woman died after apparently slipping on ice.

Among those without power was Altus Air Force Base. Other Air Force bases in the region were sending relief personnel and equipment like diesel generators, bucket lifts and line trucks.
