Yikes!
They were saying possible power outages in some areas of up to two weeks, and even in the metro areas (of Tulsa) a possibility of power outages of 5-10 days...
But, they are still revising things as they go, and have said that this is the way it seems right now, but it could shift again...
Here is the link to the 6:45 am Tulsa forecast office briefing:

Enjoy - the ice index is at 3-4 so there is a high likelihood of losing power.
