Resurgence of the northeast monsoon or "amihan" further dimmed chances for re-intensification of the low pressure area (LPA) that was once tropical depression "Auring", helping raise prospects for improving weather in parts of the Visayas and Luzon later this week.
"There's very low chance for the LPA's re-intensification," said weather forecaster Robb Gile from Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
He noted existing meteorological conditions, including resurgence of "amihan" affecting Northern and Central Luzon, aren't favorable for such re-intensification.
"The cold and dry air of "amihan" doesn't help promote the LPA's development," he said.
According to Gile, latest available data indicate the LPA's circulation is weak so it's possible for this weather system to already dissipate while within the Philippine Area of Responsibility (PAR).
Another possibility is for the LPA to exit PAR this week, he noted.
He said either way, the LPA will still likely bring rain to parts of the Visayas and Luzon before weather there begins improving.
In its weather advisory 2 released Tuesday, PAGASA located the LPA at some 225 kms west of Zamboanga del Norte province's Dipolog City as of 10 a.m.
PAGASA forecast the LPA as bringing moderate to occasionally heavy rains and thunderstorms over Eastern Visayas and Luzon's Bicol Region, Palawan and Quezon provinces.
"Residents in these areas are alerted against possible flash floods and landslides," warned PAGASA.
Light to moderate rains will prevail over Metro Manila and rest of Mimaropa Region, Calabarzon and the Visayas.
Such condition, cloudy skies and the expected moderate to occasionally heavy rains and thunderstorms over Eastern Visayas and Bicol may last until Wednesday (Jan. 11), said Gile.
"We expect weather in the areas to begin improving later this week," he said.
For Northern Luzon, PAGASA forecast occurrence of strong to gale-force winds associated with "amihan".
It warned such winds can affect Northern Luzon's northern seaboard covering Batanes province, Calayan and Babuyan islands as well as northern coasts of Cagayan and Ilocos Norte provinces.
Expected 52 kph to 63 kph winds can fan there rough to very rough seas and waves up to 4.5 meters high, PAGASA said in its gale warning 1 released Tuesday.
"Fishing boats and other small seacraft are advised not to venture out into sea while larger sea vessels are alerted against big waves," PAGASA added.
