PAGASA forecaster Mario Palafox said on dzBB radio that Domeng would also likely make landfall over eastern Mindanao, then head on towards the Visayas.
As of 4 a.m., Domeng was 880 km east of Davao City, with maximum sustained winds of 65 kph near the center, and gustiness of up to 80 kph.
Domeng was moving west-northwest at 15 kph, with its outer rain bands now affecting the eastern parts of the Visayas and Mindanao.
"Maaring mag-experience ang Mindanao at Eastern Visayas ng kalat-kalat at mahinang pagulan," he said.
Palafox added that while Domeng was too far to affect Luzon, there was a possibility that it would affect some parts of Luzon.
