The Philippine Atmospheric, Geophysical and Astronomical Services (PAGASA) advised the public on Tuesday to stay vigilant against possible flash floods or landslides triggered by the low pressure area (LPA) and southwest monsoon or "habagat" that will bring scattered light to moderate rains with occasional heavy rains to Palawan, Visayas, and Mindanao.
As of 4 a.m., Tuesday, the LPA inside the Philippine area of responsibility (PAR) was estimated at 355 kilometers (km) east of Surigao City, Surigao del Norte. This weather disturbance may develop into a tropical depression within 24 to 48 hours, according to PAGASA.
Meanwhile, the southwest monsoon is still being enhanced by tropical storm "Nika" (international name: "Nangka") although it has already left the PAR on Monday. It was estimated at 750 km west of Northern Luzon early Tuesday.
Its enhancement of the "habagat" will gradually weaken as "Nika" moves further away from the country.
Metro Manila and the rest of the country will have improved weather but may still experience short-lived heavy rains during severe thunderstorms, especially in the afternoon or evening.
PAGASA has not issued a gale warning on Tuesday but fisherfolk and seafarers are still advised to observe caution when venturing out to sea.
Moderate sea condition is expected over the waters of northern and western sections of Luzon, moderate seas across the rest of Luzon, and slight to moderate seas in the rest of the country.
