Tropical Storm Warning has gone up for Johnston Atoll as Hurricane Hector has intensified once again to a category IV storm.
Johnston Atoll has been used in the past for nuclear tests and for storing and destroying chemical munitions. The atoll is contaminated with plutonium and other radionuclides, as well as chemical contamination from mustard gas and PCBs. It was also used for biological warfare games against Navy target vessels.
Hurricane Hector has intensified to 130 mph and is projected to pass 100 to 200 miles from the island.
