The latest storm and low pressure information on the morning of August 27 from the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said that at 2:00 a.m. the same day, low pressure in the East Sea 08g formed. This new low pressure is currently inside the Philippine Forecast Area (PAR), about 190km from Dagupan, Pangasinan, Philippines.
Philippine typhoon forecasters said that the low pressure in the East Sea 08g has a moderate chance of strengthening into a typhoon and tropical depression in the next 24 hours.
Meanwhile, low pressure near the East Sea 08f is still being monitored east of the Philippines, within the PAR forecast area. Low pressure 08f is in the offshore waters of Jomalig, Quezon and is unlikely to develop into a tropical depression within the next 24 hours.
According to PAGASA weather forecasters, the low pressure near the East Sea along with the southwest monsoon is expected to cause widespread rain across the Philippines. The areas most affected will be Luzon, Visayas and Mindanao.
PAGASA pointed out that the Manila urban area, Ilocos region, Cordillera region, Cagayan Valley, Central Luzon, Calabarzon, Camarines Norte and Camarines Sur will have clouds, scattered rain and thunderstorms due to low pressure near the East Sea.
The southwest monsoon will also bring scattered showers and thunderstorms to the Visayas, Mimaropa, Zamboanga Peninsula, Northern Mindanao, Bangsamoro Autonomous Region of Mindanao, Soccsksargen and the rest of the Bicol region. The rest of Mindanao could see scattered clouds, showers or thunderstorms.
Heavy rain is forecast for Palawan, Western Mindoro, Oriental Mindoro, Antique and Negros Western between the afternoon of August 27 and the afternoon of August 28.
PAGASA noted that the rainfall may be greater in mountainous and highland areas, with the worst impact likely in provinces that have experienced heavy rain in recent days.
PAGASA recommends that local people and disaster risk reduction agencies take measures to prevent floods and landslides.
Due to bad weather forecasts, the Civil Aviation Authority of the Philippines recorded a number of domestic flights being canceled for safety reasons. Court activities in some areas were also affected.
