Earth’s stongest storm of 2013, packing 160 mph winds, moving toward Hong Kong
Super Typhoon Usagi, the equivalent of a Category 5 Atlantic hurricane, intensified rapidly Thursday in the western Pacific Ocean and will threaten parts of Taiwan, the far northern Philippines and southern China through the next several days.
A tropical cyclone is dubbed a “super typhoon” when maximum sustained winds reach at least 150 mph. Usagi underwent a period of rapid intensification from early Wednesday through midday Thursday (U.S. Eastern time), going from a 55-knot tropical storm to a 140-knot super typhoon in just 33 hours, or just under a 100 mph intensification, based on satellite estimates of intensity.
