Two new low-pressure area (LPA) systems within the Philippine Area of Responsibility (PAR) are being monitored by the state weather bureau, including Tropical Storm “Peipah”.
Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) weather specialist Ariel Rojas said as of 3 p.m. Monday, the first LPA was estimated based on all available data at 280 kilometers west of Iba, Zambales.
“Mababa ang tsansa na ito ay maging isang bagyo at ito rin ay tumutulong sa paghila sa ating southwest monsoon,” Rojas said.
The other LPA was located at 895 kilometers east northeast of Basco, Batanes.
Rojas said tropical depression Marilyn had a wide circulation, which means creating a vortex or a mass of whirling fluid or air.
“Matatandaan natin na noong nakaraang linggo, napakalawak or broad itong circulation ni TD Marilyn. Ang nangyayari kapag malawak ang sirkulasyon ng isang weather disturbance, may mga posibilidad ng mga nabubuong vortices o sirkulasyon at itong LPA sa Basco, Batanes ay isa sa mga naging anak ni TD Marilyn,” he said.
Peipah, on the other hand, has been located 2,295 kilometers east of extreme northern Luzon with maximum sustained winds of 65 kilometers per hour near the center and gustiness of up to 90 kilometers per hour.
He said it is moving towards the northwest at 45 kilometers per hour.
MIMAROPA, including Palawan, will have cloudy skies with scattered rain showers and thunderstorms caused by the trough of the LPA.
Possible impacts could be flash floods or landslides due to occasional heavy rains.
