The Philippines evacuated tens of thousands of people from their homes and cancelled dozens of flights on Saturday, as a super typhoon threatened to unleash heavy rains and powerful winds that could trigger floods and storm surges.

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.

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.
