Development of a low-pressure area (LPA) is expected to be observed in the last week of November, according to the numerical prediction model of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

In an interview with local chief Sonny Pajarilla on Friday, he said they are not monitoring any LPA yet inside the Philippine Area of Responsibility (PAR) but there is an active intertropical convergence zone (ITCZ) in the southeastern part of Mindanao.

“So far ngayon, wala pang full fledge na low-pressure system. Ayon nga lang, medyo aktibo ‘yong ITCZ sa malayong timog silangang bahagi ng Mindanao. Base sa numerical model guidance, maaaring may mabuo next week, maaaring may pumasok sa PAR na low-pressure area between Thursday hanggang Sabado,” he said.

He said that Palawan is experiencing fine weather due to the prevailing of easterly winds. There is a high chance of thunderstorm development that will result in partly cloudy conditions at noontime to the afternoon.

Meanwhile, tropical storm Sarah is expected to leave PAR between 11:00 in the evening to 05:00 in the morning on Saturday.

Pajarilla said that even if tropical storm Sarah is still within the PAR, it will no longer affect any landmass of the country.
