Typhoon Usagi made landfall in the Philippines on Thursday as the authorities warned that the storm could cause widespread flooding and landslides in the north of the country.

Usagi, called Ofel in the Philippines, is the fifth major storm to hit the country in the past three weeks. The other four — Toraji, Trami, Yinxing and Kong-rey — killed more than 100 people and caused destruction. This week, four tropical storms churned at once in and around the South China Sea and the North Pacific, the first time that had happened in the region in November since records began.
