The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) is monitoring a low pressure area within the Philippine Area of Responsibility (PAR) east of Mindanao.
On the morning of March 28, the low pressure was located 95 km east of Hinatuan, Surigao del Sur.
The low pressure area is expected to move westward, closer to the Visayas and could weaken by the weekend, according to weather expert Aldczar Aurelio.
The low pressure, which is likely to develop into a "not-high" tropical depression, will bring rain to the Visayas and some parts of Mindanao.
Tourists in the Philippines should pay attention to the warning of the risk of flash floods or landslides in areas forecast to have thunderstorms.
It is currently the dry season (December - May) in the Philippines, visitors can still experience scattered rains due to the influence of low pressure and winter winds.
Currently, this low pressure area near the East Sea does not affect the marine weather in Vietnam.
However, the cold air mass will strengthen in the North and will affect the northern seas.
