The super typhoon, which has attained sustained winds of 150 mph and gusts of up to 184 mph, threatens flash floods and landslides in the mountainous region.
The Noul super typhoon is forecast to hit the northeastern tip of Luzon, the largest and most populous island in the Philippines, later on Sunday.
Noul could also impact the Japanese prefecture of Okinawa early next week, according to earlier warnings.
The Philippines is routinely affected by typhoons during the monsoon rains period from June to December.
In late 2013, the Philippines was hit by a deadly Super Typhoon Haiyan, which left over 6,300 people dead.
