Authorities on Mexico\'s Gulf coast prepared for Tropical Storm Nate\'s arrival Saturday while air and sea search teams hunted for 10 oil workers missing since abandoning a disabled research vessel in stormy waters, AP reported. Nate was still moving toward the coast very slowly, but was expected to pick up some speed Saturday, said the U.S. National Hurricane Center in Miami. Forecasters said the storm would approach the coast Sunday, mostly likely just below hurricane strength. Mexico\'s state oil company, Petroleos Mexicanos, had two ships searching for the missing oil workers. A port official said Friday that they included four Americans, four Mexicans, one from Kazakhstan and a 10th of unconfirmed nationality.
