The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said that at 2:00 a.m. on August 26, the center of the low pressure was at 13.8 degrees North latitude, 122.8 degrees East longitude, in the coastal waters of paracale, Camarines Norte. The low pressure is likely to strengthen into a tropical depression in the next 24 hours.
The low pressure and southwest monsoon will bring rain and thunderstorms across the country on August 26.
Weather forecaster Obetrina Badrina said that if the depression does indeed become a tropical cyclone, it could only form during the day and eventually dissipate as it moves west.
The low pressure is forecast to bring heavy rain to the areas of Isabela, Aurora, Bulacan, Quezon, Laguna, Rizal, Camarines Norte, Camarines Sur, Albay, Sorsogon, Catanduanes and Masbate.
Floods can occur mainly in urbanized areas, low-lying areas or near rivers. Earthquakes can occur in vulnerable areas.
The Manila urban area, Cagayan Valley, Cordillera Administrative Region, Central Luzon, the rest of the Bicol Region and Eastern Visayas will experience cloudy skies with scattered showers and thunderstorms due to low pressure.
Meanwhile, Mimaropa, the Zamboanga Peninsula, BarMM, Northern Mindanao, Caraga and the rest of Visayas will also experience cloudy skies with scattered showers and thunderstorms due to Typhoon Habagat.
The remaining areas of the country will have cloudy to cloudy skies with scattered showers or thunderstorms due to local thunderstorms.
Meanwhile, according to the US Joint Typhoon Warning Center (JTWC), the low pressure system Invest 93W in the Philippines is gradually strengthening, although the circulation is still wide and the wind is light. The low pressure is unlikely to yet become a typhoon before sweeping across Luzon Island on the morning of August 26.
However, after reaching the South China Sea and merging with the monsoon disturbances in West Mindoro on August 27, the depression has favorable conditions to strengthen. The low pressure is forecast to develop into a tropical depression from August 28 or 29, moving west towards Vietnam. The JTWC assessed the possibility of the low pressure developing in the next 7 days at 70%.
