The most powerful typhoon of the 2013 season approached the northern Philippines and southern Taiwan on Friday (Sept. 20) with wind reaching 300 kph (184 mph) and torrential rain. The death toll now stands at 475 and is expected to increase dramatically in the days to come. Usagi has a diameter of 1,100 kilometers (660 miles), with outer rain bands extending across the main northern Philippine island of Luzon and southern Taiwan. Forecasters predict 24-hour rainfall accumulation of 500 millimeters (nearly 20 inches) near its center. Presentation courtesy of Dr Walter Hays, Global Alliance for Disaster Reduction
