More than 43,000 people have been evacuated and schools in six provinces have suspended classes as the eastern islands of the Philippines were lashed Tuesday by heavy rains from Typhoon Kammuri after it made landfall late Monday.

The storm, packing wind gusts as high as 150 miles per hour, was battering the Philippines on Monday night and into Tuesday, after its eye made landfall near Gubat, a city on Luzon island, the national weather agency said.

Officials ordered the closing of Manila’s main airport for 12 hours starting at 11 a.m. Tuesday, and the Philippine Coast Guard ordered a halt to marine traffic in affected areas.

The typhoon struck the Philippines just after President Rodrigo Duterte, joined by the politician and boxing star Manny Pacquiao, presided over the opening of the Southeast Asian Games, a biennial sports event that draws top athletes from 11 Southeast Asian nations.
