Typhoon Mangkhut, the world's strongest storm this year, continued its path of destruction across Southeast Asia, reaching mainland China after pummeling Hong Kong and killing dozens in the Philippines, authorities said on Monday.

Mangkhut is now expected to move inland of China's western Guangdong on Monday. While the storm has weakened, a T8 warning was still in place into Sunday evening - meaning that winds with speeds of about 63 kph were expected. The storm has carved a deadly trail across the region, killing two people in southern China and at least 54 people in the Philippines, with more than 2,50,000 people affected.
