A super typhoon steadily battered a pair of remote U.S. islands in the Pacific Ocean with ferocious winds and relentless rains, shredding tin roofs and forcing residents to take cover from flying tree limbs. Super Typhoon Sinlaku pounded the Northern Mariana Islands for hours before daybreak Wednesday, slowing just to inflict more damage across the islands of Tinian and Saipan, home to nearly 50,000 people. The National Weather Service says the tropical typhoon was packing sustained winds of up to 150 mph when it made landfall on the islands. The weather service says tropical force winds and torrential rainfall also led to flash flooding on Guam, a U.S. territory to the south with several U.S. military installations and about 170,000 residents.
