Residents in northeast Oklahoma are cleaning up after storms moved through the area early Sunday morning.

Wind gusts were measured at 90 miles per hour as a strong line of storms moved through Tulsa and the surrounding area. A spotter-confirmed tornado prompted a warning near Oologah and another tornado warning was issued near Adair. Many communities also sounded sirens due to high winds.

Public Service Company of Oklahoma says this is the most significant restoration event since the 2007 ice storm. During this weekend's storm, power equipment sustained substantial damage including transmission structures, broken poles, cross-arms and downed wires. Crews continue to work to safely restore power. PSO says this is going to be a multiple-day effort. This morning, outages are concentrated in the Tulsa and McAlester areas, and approximately 166,000 customers remain without power.
