Taiwan is bracing for a deadly typhoon headed north from the Philippines, where it lashed the main island of Luzon with days of torrential rains and high winds, killing at least eight people.

Late Sunday, forecasters placed the slow-moving Typhoon Nanmadol about 250 kilometers south of Taipei. Official media reported evacuations of coastal areas were under way. The storm is expected to strike near Taiwan's port city of Khaosiung late Monday or early Tuesday before raking the island's eastern coast.

Nanmadol made landfall in the northern Philippines Saturday morning, with maximum winds exceeding 150 kilometers an hour. Philippine emergency officials say they expect the death toll to rise as reports come in from remote areas of mountainous northern Luzon. Authorities say most of the known victims, including several children, died in mudslides. At least six others were missing Sunday and thought to have been swept out to sea.

More than 100,000 people across 11 Philippine provinces have been affected, and many were without electricity.

Authorities say about 20 tropical cyclones enter Philippine territory in a typical year and, of those, 6 to 9 normally make landfall. The country's deadliest storm on record struck eastern islands of the archipelago in November 1991, killing an estimated 7,000 people.
