In an interview, Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) weather forecaster Manny Mendoza said typhoon "Ineng" was located based on all available data at 1,420 kilometers east of Aparri, Cagayan (18.3°N, 135.0°E) packed with maximum sustained winds of 170 kilometers per hour (kph) near the center and gustiness of up to 205 kph.
He said the typhoon is forecast to move west-northwest at 20 kph.
The typhoon is not yet affecting the country, but will enhance the southwest monsoon or "hanging habagat" which will bring rains over the Visayas and Mindanao by Wednesday, Mendoza said.
He added that by Thursday until weekend, rains will be experienced in the western part of Northern, Central and Southern Luzon, including Metro Manila.
Mendoza said the typhoon has high chance to make landfall in extreme Northern Luzon or in the province of Batanes or in Calayan by Friday because of the presence of a high pressure area (HPA) that blocks its movement.
However, he noted that once the HPA recedes, it will not make any landfall as it will follow the track of typhoon "Hanna" which only enhanced the southwest monsoon.
He also said that by Thursday or Friday, the state weather bureau may raise public storm warning signals over the provinces of Northern Luzon as the typhoon moves closer to the area.
If it maintains its speed and movement, Mendoza said the typhoon is expected to exit the PAR by Saturday morning as it will recurve and head toward Japan.
He added that for the coming days, the agency will issue gale warning due to the typhoon-enhanced southwest monsoon as the fisherfolks are not safe to venture into the sea.
Meanwhile, Mendoza said the other typhoon with international name "Atsani" has a slim chance to enter the country as its track is moving toward Japan.
However, the agency continues to monitor it and once it enters the PAR, it will be locally named "Jenny." (PNA)
