MANILA — The typhoon with international name “In-fa” is expected to enter the Philippine Area of Responsibility (PAR) on Sunday evening, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
PAGASA weather forecaster Aldczar Aurelio said that as of 4 a.m. Sunday, the eye of typhoon “In-fa” was still outside the PAR — some 1,400 kilometers east of Samar (12.8°N, 137.5°E) — packed with maximum sustained winds of 175 kilometers per hour (kph) near the center and gustiness of up to 210 kph. It is forecast to move west- northwest at 25 kph.
Once it enters the PAR, the typhoon will be named “Marilyn” — the 13th tropical cyclone to affect the country this year, Aurelio said.
He added that once inside the PAR, the typhoon will not directly affect the country and is not expected to make landfall but the agency will continues to monitor it.
Aurelio said if it maintains its speed and movement, the typhoon is expected to exit the PAR by Wednesday or Thursday headed towards Japan.
Meanwhile, the inter-tropical convergence zone (ITCZ) remains the prevailing weather system that is currently affecting Mindanao.
Cloudy skies with rains are expected over parts of Eastern Visayas and Mindanao on Sunday due to the presence of ITCZ.
Aurelio said the ITCZ affecting Mindanao is the thick clouds coming from the south of Asia and considered a breeding ground for low-pressure areas (LPAs) or potential cyclones.
He said cloudy skies with light to moderate rains and isolated thunderstorms will prevail over Eastern Visayas and Mindanao.
He added that fair weather continues in the rest of the country, including Metro Manila except for isolated thunderstorms.
In its advisory, PAGASA said moderate to strong winds blowing from the northeast will prevail over Luzon and the Visayas and the coastal waters along these areas will be moderate to rough.
Elsewhere, winds will be light to moderate coming from the northeast with slight to moderate seas.
The state-run weather bureau also issued a gale warning due to the effects of the northeast monsoon as the sea condition would be rough to very rough due to strong to gale force winds expected to affect the Northern and Eastern seaboards of Luzon and the Eastern seaboard of the Visayas.
“Fishing boats and other small seacraft are advised not to venture out into the sea while larger sea vessels are alerted against big waves,” it warned. PNA
