"Forecast rainfall are generally higher in elevated or mountainous areas," PAGASA said.

"Under these conditions, flooding and rain-induced landslides are possible especially in areas that are highly or very highly susceptible to these hazards as identified in hazard maps and in localities that experienced considerable amounts of rainfall for the past several days," it added.

Hazards affecting coastal waters

PAGASA said that Aghon will bring moderate to rough seas (1.5 to 3.5 meters) over the coastal waters along the seaboards of Bicol Region, southern Quezon, eastern Eastern Visayas, western Samar and Northern Samar, and eastern Caraga Region on Saturday.

It also advised mariners operating motor bancas and similarly-sized vessels to take precautionary measures and avoid navigating these waters if possible, especially if inexperienced or operating ill-equipped vessels.

Track and intensity outlook

According to PAGASA, Aghon will move generally northwestward over the Samar Sea and cross the Bicol Peninsula between Saturday afternoon and early Sunday morning.

It is expected to emerge over Lamon Bay or the waters north of the Camarines Provinces by early Sunday morning.

Another landfall is possible in the vicinity of the Polillo Islands on Sunday morning. During this period, Aghon may reach tropical storm category.

It may exit the Philippine Area of Responsibility (PAR) no earlier than Tuesday.
