Typhoon Usagi weakened sharply on Friday after bearing down on the Philippines' northern towns, blowing away houses in its path as authorities brace for another storm that could hit the capital Manila over the weekend.

Typhoon Usagi slammed into the Philippines' already disaster-ravaged north on Thursday, as authorities rushed to evacuate thousands of people from coastal areas.

Typhoon Usagi blew out of the Philippines early Friday as another dangerous storm drew closer, threatening an area where scores were killed by flash floods and landslides just weeks ago, the weather service said.
