Tropical cyclone Man-yi has strengthened into a super typhoon, threatening to bring intense rains and high waves on the Philippines’ main island that’s still reeling from a string of storms in recent weeks.

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.

The fifth major storm in three weeks is approaching the Philippines, prompting more largescale evacuations and a United Nations request for emergency funds to help the government ease the plight of hard-hit villagers.
