In the 5 a.m. bulletin, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said the low pressure was determined to be about 80 km east-northeast of Cuyo town, also in this province, and was within the Philippine area of responsibility.
Pagasacho weather expert Benison Estareja said: "This low pressure area is not yet likely to develop into a storm and may dissipate within the next 24 hours".
Pagasa said the low pressure area will affect the Visayas, Calabarzon, Mimaropa, Bicol and Zamboanga peninsula regions, which are forecast to have cloudy weather with scattered thunderstorms.
The Philippine Meteorological Agency warns residents and tourists to be on guard against the risk of flash floods or landslides due to moderate to heavy rain, sometimes very heavy rain in some areas in the archipelago.
Metro Manila and the rest of the Philippines are expected to see partly cloudy to gloomy skies, accompanied by scattered showers or thunderstorms over the next 24 hours.
The low pressure has not yet affected the weather in the coastal areas of Vietnam. According to the National Center for Hydro-Meteorological Forecasting, it is forecasted that on the day and night of May 8, most sea areas from the Gulf of Tonkin to the Gulf of Thailand, Truong Sa archipelago and Hoang Sa archipelago will have scattered showers and thunderstorms, with a long view of over 10km.
In particular, the Northeast of the East Sea will have scattered showers, thunderstorms in some places, with the possibility of tornadoes and strong gusts of wind.
