THE state-run weather agency said on Thursday that a low pressure area (LPA) still outside the Philippine Area of Responsibility (PAR) may develop into a tropical depression once it enters the country and would be named "Rosal".
Weather specialist Benison Estareja of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) told The Manila Times that the LPA was last spotted some 1, 265 kilometers east of Mindanao (outside PAR).
He said its trough or extension is affecting the eastern sections of Visayas and Mindanao where cloudy skies with scattered rain showers and thunderstorms may prevail over the next 24 hours.
Meanwhile, the shear line or the point where the warm and cold air converge is bringing rains over Northern Luzon particularly in Cagayan, Apayao and Ilocos Norte, Pagasa said.
Quoting Pagasa's latest forecast, Estareja said the LPA will likely enter within the day (Thursday) and will move towards Eastern Visayas and Bicol Region.
"It has a moderate chance to become a tropical cyclone," said Estareja although he declined to say if this would further escalate into a tropical storm in the coming days.
In case the LPA will develop into a storm, it will have a domestic name of "Rosal", the 18th cyclone this year and the first this month, the Pagasa forecaster said.
Over Metro Manila and the rest of the country, the weather bureau said generally fair weather is likely over the next 24 hours although partly cloudy to cloudy skies with isolated rain showers or thunderstorms may be experienced in late afternoon and night time due to the localized thunderstorms.
