HANOI, Vietnam -- Haiyan made landfall in northern Vietnam on Monday as a tropical storm, just days after leaving massive destruction in the Philippines as the season's strongest typhoon.

The Vietnamese national weather agency said Haiyan made landfall in the northern province of Quang Ninh and was moving toward southern China.

State media quoted the National Search and Rescue Agency as saying that 13 people died and 81 others were injured while reinforcing their houses and trimming trees before Haiyan made landfall. The agency said the storm damaged more than 1,300 houses and 39 fishing boats in Quang Ninh.

It slammed into six central Philippine islands on Friday as the strongest typhoon of the year and one of the strongest on record. It appeared to be the deadliest storm -- and natural disaster -- on record to hit the Philippines, with officials saying that as many as 10,000 people are feared dead.

The storm was expected to further weaken later Monday while dropping heavy rain on the Chinese provinces of Guangxi and Hunan. Guangxi officials advised fishermen to stay on shore and told residents to take precautions against flooding and landslides.
