At least two people have been killed as a violent thunderstorm struck the Great Smoky Mountains National Park. A man on a motorcycle was killed and a 41 year old woman when a tree fell on them. Names of the victims are being withheld pending notification of family members. The storms hit Thursday evening at the west end of the park on the Tennessee-North Carolina border. Most of the damage appears to be in Cades Cove. (jb)
