The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said it is monitoring a low pressure area forming outside the Philippine Forecast Area (PAR).
At 2:00 a.m. on June 29, the center of the low pressure was at about 14.9 degrees north latitude, 135.6 degrees east longitude, about 1,240 km east of southeast Luzon. According to PAGASA's initial assessment, the possibility of this low pressure area strengthening into a tropical depression or storm in the next 24 hours is low.
If it maintains its current direction, the low pressure area is likely to move northwest to the northeastern part of Luzon from July 1 to July 4, bringing widespread thunderstorms in Luzon and the Visayas.
At the same time, thunderstorms were also reported in Metro Manila, tarlac, Pampanga, Bataan, Batangas, Cavite, Laguna, Quezon and Rizal due to strong convective clouds.
PAGASA said that due to the influence of the southwest monsoon, thick clouds and heavy rain will cover many areas of the country's west on June 29.

Although the low pressure area is far away and has not shown any clear signs of strengthening, meteorological experts continue to closely monitor as weather fluctuations in the Philippine Sea may become complicated in the coming days, especially when the rainy season is at its peak.
People in high-risk areas are advised to regularly monitor weather forecasts from authorities to promptly respond in case this weather pattern changes faster than expected.
Meanwhile, according to the Vietnam National Center for Hydro-Meteorological Forecasting, on June 29, there will be showers and thunderstorms in the following areas: the North of the Gulf of Tonkin; the North East Sea (including the Hoang Sa archipelago); the sea area east of the central East Sea; the Gulf of Thailand. On Phu Quy island, there are southwest winds of level 5, sometimes level 6, gusting to level 7.
It is forecasted that on the night of June 29 and June 30, the following seas will continue to have showers and thunderstorms: Gulf of Tonkin; North and Central East Sea (including the sea area of Hoang Sa archipelago); Gulf of Thailand. During thunderstorms, there is a possibility of tornadoes, strong gusts of wind of level 6-7, waves over 2m high.
Sea area from Ninh Thuan to Ca Mau: Strong southwest wind level 5, sometimes level 6, gust level 7, waves 2-3m high, rough seas.
