The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Monday that it is not expecting any low-pressure area (LPA) that can develop into a tropical depression in the next 10 days.
“Wala tayong low-pressure area na present ngayon base dito sa ating forecast. Wala ring inaasahan na mamumuo within the next days bago pa man matapos ang buwan ng Mayo,” Pajarilla said.
He said the south-westerly wind is still prevailing but the absence of the LPA that could trigger the onset of the rainy season with significant volume will not occur.
Thunderstorms will be observed briefly during the afternoon as heavy rains in the southern areas continue, he added.
On Saturday, a netizen posted a video of a strong water flow in Estrella Falls in Narra town believed to be caused by strong rains in the mountain.
Pajarilla said the flashflood-like incident that happened was probably caused by an isolated thunderstorm.
“Isolated thunderstorm, kahapon nga may malakas na (ulan) sa south ng Narra… sa pagitan ng (Barangay) Abo-Abo hanggang Narra… meron at napalakas dyan kahapon, halos bumaha, mag-flash flood pero pagdating sa bayan ng Narra, localized thunderstorm ang tawag natin,” he added.
He also said this is “normal” because it is the kind of rain that occurs during the dry season.
In June, the southwest monsoon or habagat is expected to arrive with thunderstorms also occurring, Pajarilla said.
