High waves for the next several days will hamper the search for 12 Marines missing at sea after two helicopters collided near the island of Oahu in Hawaii, U.S. Coast Guard officials said on Friday.
Two Coast Guard cutters and several Coast Guard aircraft were searching, along with two U.S. Navy warships and local police and fire department helicopters, the Coast Guard said.
A safety zone has been set up from the shoreline that matches up with the accident site to 8 miles (13 km) out to sea, the Coast Guard said.
“We’ve seen debris through the entire area,” said Lieutenant Scott Carr, a Coast Guard spokesman. He added the high surf was expected to last until at least Tuesday.
