Typhoon Krosa is unleashing its fury on the Philippines' northern Luzon Island, then will begin its journey toward Vietnam on Friday. Typhoon Krosa will then spend Thursday night tracking along the far northern coast of Luzon. Damaging wind gusts in excess of 100 kph (60 mph) are expected across northern Luzon, well north of the capital city of Manila and other highly populated areas. The heaviest rainfall will also be north of Manila.

According to Accuweather.com Meteorologist Eric Wanenchak, "125-250 mm (5-10 inches) of rainfall is expected across northern Luzon through Friday as Krosa passes over the area from east to west." This amount of rainfall will produce flooding problems and potential mudslides.

Some rain associated with Krosa will also spread over eastern Taiwan through Friday, threatening to hinder earthquake cleanup efforts. While the interaction with Luzon will cause some weakening, Krosa will still be a typhoon when it reaches the South China Sea on Friday.

Krosa will then remain over open water through the weekend, tracking as if it is heading toward Hong Kong through Saturday before curving to the southwest away from mainland China by Sunday
