All seven of the people listed as missing following a series of strong tornadoes late Wednesday have now been accounted for in Granbury, Texas, leaving the death toll at six, authorities said Friday. Workers were clearing debris to allow residents of the most damaged area to return to see the destruction, and volunteers have arrived to help with the massive cleanup effort, said Texas Department of Public Safety spokesman Lonny Haschel. The search for survivors is complete, and everyone is accounted for, Haschel said. Fifty people were taken to area hospitals for injuries, and another 90 were treated for minor injuries at the scene, he said. “Crews are trying ... to make sure it's safe for people to return," Haschel said. “There is still debris everywhere, and some still falling off the houses, so we want to make sure it is safe." The biggest of 16 confirmed tornadoes, which had winds around 300 kilometers per hour (kph), was rated an EF-4 by the National Weather Service (NWS), the second-most powerful level for such a storm.
