Entergy Arkansas spokeswoman Julie Munsell said some customers who lost power during the Christmas Day blizzard could be without service until 2013. Based on the 2000 ice storms, it is possible that some residents won't have their electricity turned back on for seven days.
Entergy Arkansas saw 191,000 customers without service at the peak Wednesday morning, and combined with other utilities the number of homes and businesses without service exceeded 200,000.
Freezing rain, sleet and snow combined to bring down power lines - either snapping lines or the poles themselves. In other places, trees fell into wires, pulling them down.
Repair crews are dealing with wind and slippery roads.
