Usagi was a typhoon in the South China Sea Friday morning Philippine Time, the Joint Typhoon Warning Center said in its latest advisory. The typhoon had sustained wind speeds of 81 miles per hour, which would make it a Category 1 hurricane if it were in the Atlantic Ocean.

Category 4 Typhoon Usagi and Tropical Storm Man-yi are next on the list of storms expected to strike the region.

Typhoon Usagi struck the northern Philippines on Thursday afternoon, the fifth powerful storm to impact the country in three weeks, with the system set to swing north and move toward Taiwan.

The storm made landfall on the island of Luzon. Forecasters warned of torrential rain and landslides in the north of the country.
