Typhoon Mangkhut: Storm Slams Philippines on Landfall

Typhoon Mangkhut struck the Philippines early Saturday after thousands of people evacuated their homes to dodge the 550-mile-wide storm as it roared across the Pacific.The ferocity of the storm — with maximum sustained winds of around 120 miles per hour — in some ways eclipsed Hurricane Florence on the other side of the world, which was pummeling the Mid-Atlantic Coast of the United States with life-threatening rains and flooding.As dawn was breaking in the Philippines, there was no official word on casualties or damage.The eye of Mangkhut, known as Ompong in the Philippines, made landfall on the northeastern portion of Luzon island, the country’s rice- and corn-growing heartland, at about 1:40 a.m.[Catch up on the rest of our storm coverage.]
