Cloudy and rainy weather will prevail in most parts of the country on Wednesday because of the presence of an Intertropical Convergence Zone (ITCZ) affecting Mindanao while Typhoon “Ompong” (international name: Vongfong) has intensified, according to Philippine Atmospheric, Geophysical Astronomical Services Administration (PAGASA).
ITCZ, which is the thick clouds coming from the south of Asia, is considered a breeding ground for low-pressure areas (LPAs) or potential cyclones.
In an interview, PAGASA weather forecaster Gener Quitlong said due to ITCZ outer rain cloud bands which will bring cloudy skies with light to moderate rainshowers over Metro Manila, Calabarzon (Cavite, Laguna, Batangas, Rizal and Quezon) Mimaropa (Mindoro, Marinduque, Romblon and Palawan), Bicol Region, Visayas, Zamboanga Peninsula, Northern Mindanao, ARMM, SOCCSKSARGEN, Cagayan Valley, CAR and the provinces of Ilocos and Aurora.
He added the rest of the country will be partly cloudy to cloudy with isolated rainshowers or thunderstorms.
Meanwhile, Quitlong said Ompong has intensified its maximum strength from 160 kilometer per hour (kph) on Tuesday to 215 kph while its gustiness also rose from 195 kph to 250 kph.
As of 4 a.m., the eye of Typhoon Ompong was located based on all available data at 1,161 km east of Tuguegarao City (17.8ºN, 133.0ºE). It is forecast to move west northwest at 17 kph.
It is expected to change its movement from westward to northward in the coming days due to the presence of ridge of high pressure area.
He added that “Ompong” will likely follow the track of typhoon “Neneng” as it heads toward southern Japan.
Quitlong said the typhoon is still too far to affect the country and is not expected to make landfall in any part of the country.
However, Quitlong said Typhoon Ompong is expected to enhance the northeasterly winds which will result to rough to very rough sea conditions over the seaboards of Northern Luzon and the eastern seaboard of Central and Southern Luzon.
“Fisherfolks and those using small seacrafts are advised not to venture out over the said seaboards,” PAGASA warned.
The estimated rainfall amount is from 7.5–25 mm per hour (heavy–intense) within the 700 km diameter of the typhoon.
In its advisory, PAGASA said moderate to strong winds blowing from the northeast to northwest will prevail over Luzon and its coastal waters will be moderate to rough.
Elsewhere, winds will be light to moderate coming from the southwest to west with slight to moderate seas. PNA
