Pagasa said estimated rainfall amount is from 5 – 15 mm per hour (moderate – heavy) within the 550 km diameter of the typhoon.
Typhoon “Igme” is expected to enhance the southwest monsoon that will bring light to moderate rains over Luzon especially the western section particularly Pangasinan, Zambales, Bataan, Batangas and Mindoro.
It said fishing boats and other small sea crafts are advised not to venture out into the eastern seaboards of Central and southern Luzon due to big waves caused by typhoon and the southwest monsoon.
