BEIJING, Sept. 20 (Xinhua) -- China's national observatory on Friday maintained a warning for super typhoon Usagi, which was expected to hit coastal region of southern Guangdong Province on Sept. 23.
The center of Usagi, one of the strongest typhoons to hit China's southeastern coast this year, was at 625 kilometers southeast of Taiwan's Cape Eluanbi early on Friday, and would continue to strengthen and move northwestward at a speed of up to 20 km per hour, the National Meteorological Center forecast.
The center said Usagi would bring strong gales to sea waters of the Taiwan Strait and east of Taiwan on Friday and Saturday.
It also forecast that a cold front would sweep across most parts of China from Sept. 21 to 25. Temperatures in Gansu Province as well as Xinjiang Uygur and Inner Mongolia autonomous regions were expected to fall on Saturday, with thermometers in some Xinjiang regions plunging by up to 12 degrees Celsius.
