JOHNSTON ISLAND (AP) - As a hurricane approached, the U.S. Army evacuated military and civilian workers Monday off a small central Pacific island that is home to an Army chemical weapons incineration facility. Most of the 1,300 military and civilian workers on Johnston Island, part of a four-island atoll located 825 miles southwest of Honolulu, were evacuated. Officials closed tanks and lines in the weapons incinerator, securing the rest of the weapons in storm-proof bunkers. Hurricane Dora was forecast to pass 7 miles north of the island Tuesday night, close enough for forecaster National Weather Service Jeff Powell to call it a direct hit.
