Heavy ice is blamed for thousands of power outages that persist across the FOX 7 viewing area. The weight of ice on tree limbs is causing some of them to touch lines, creating an electrical arc which blows fuses along the power grid. More troubling for power crews are the tree limbs and branches that fall and snap lines and power poles. Tuesday, Vectren reported about 3,000 customers still without power, but as of Wednesday, nearly everyones power is back on. In Kentucky, Kenergy and Kentucky Utilities are reporting around 8,000 outages. Several shelters have been set up for those without power and without heat. The Evansville Red Cross has one shelter open at its headquarters on Stockwell Road. There is also a shelter in Boonville at the Main Street Baptist Church, as well as shelters in Clay, Kentucky, McLean County, Kentucky and Hopkins County, Kentucky.
