The Coast Guard is conducting an active search for six crew members of a U.S. cargo vessel that lost engine power and radio contact off Guam during Typhoon Sinlaku on April 16. A search aircraft had to return due to heavy winds but operations are resuming at first light, with the vessel's last known position about 125 miles north-northwest of Saipan. The typhoon brought typhoon-force winds spanning 275 miles and created hazardous seas with swells up to 20 feet — conditions that delayed responders from assessing the full damage across the Northern Mariana Islands and Guam.
