Aug. 25 (UPI) -- A powerful typhoon made landfall in northeast Vietnam, prompting schools and airports to close and prompting people to evacuate.

Typhoon Kajiki threatens the country with destructive winds and storm surges. It downed trees and brought heavy rains to China's Hainan Island on Sunday before moving over the Gulf of Tonkin overnight with sustained wind speeds of 103 mph, according to Vietnam's national weather forecast agency. It's equal to a Category 2 Atlantic hurricane.

More than 586,000 residents have been evacuated. Schools and public buildings have been converted into temporary shelters, according to Vietnamese authorities. Those still at home have been told not to leave their homes between 11 a.m. and 6 p.m. local time.

Kajiki made landfall in the central provinces of Thanh Hoa and Nghe An late afternoon. Thanh Hoa is about 103 miles south of Hanoi and includes the city of Vinh.
