Hong Kong residents huddled indoors Sunday as Typhoon Mangkhut, the world’s strongest storm this year, carved a destructive and deadly path from the Philippines into mainland China. Fierce winds have already torn off roofs, smashed windows and downed trees in Hong Kong, as authorities warned of the threat of storm surges and flooding from torrential rain.

Typhoon Mangkhut made landfall early Saturday, September 15, threatening more than 4 million people in the northern Philippines and killing at least 54. The massive storm, the equivalent of a Category 5 hurricane, brought gale-force winds and heavy rains, causing flooding and setting off landslides.

Mangkhut has already torn through Guam and the Marshall Islands in the Pacific Ocean.
