Suspected tornadoes cause injuries, damage in Arkansas Sat Dec 21, 2013 10:41pm EST (Reuters) - Suspected tornadoes wreaked havoc in Arkansas on Saturday, injuring several people, damaging some homes and in one case sweeping trucks off a highway, officials said. The most widespread damage was near Dermott, Arkansas, in the southeast corner of the state, where five homes were seriously damaged, 15 suffered minor damage and four semi-trucks were blown off a highway, said National Weather Service meteorologist David Cox in Jackson, Mississippi. Two people were injured, he said. "We are thinking it was a tornado," Cox said. We had quite a bit of rotation and quite a bit of damage. The storm hit at about 5 p.m. local time, he said. The same weather system crossed the state line into Boliver County, Mississippi, where winds clocked at 64 mph downed power lines and trees and damaged some buildings, Cox said. A possible tornado injured several people and damaged a few homes on Saturday near the town of Hughes in eastern Arkansas, officials said. The windstorm struck at about 4 p.m., said dispatcher Lynn Morgan of the Saint Francis County Sheriff's Office. The storm has not yet been classified as a tornado by the National Weather Service, he said. A turbulent weather system was moving late Saturday from the south central United States into the Midwest, according to the National Weather Service. The National Weather Service has posted tornado watches on the southern end of the system and winter storm warnings to include ice, sleet and 4 to 8 inches of snow from eastern Kansas into Michigan late Saturday and early Sunday.
