According to reports, stretched by the Kauai flood disaster and other missions, Coast Guard capabilities are nearly maxed out and the service is asking the Navy to help, a Coast Guard spokeswoman said. The Coast Guard had a full plate even before the disaster. Its aircraft have been performing interisland air ambulance services since the crash on Maui last week of a plane operated by Hawaii Air Ambulance. The Coast Guard has been scouring the seas off Kilauea since Tuesday, when a dam collapse let loose a torrent of floodwaters that left seven people missing. Coast Guard crews found an unidentified male later that day about a mile offshore. The body of a female was found in a streambed yesterday afternoon.
