The two low pressure areas are being monitored in the Philippine Area of Responsibility on May 7, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration ( pagasa).
As of 3:00 a.m. on May 7 (local time), the two low pressure areas were identified 425 km west of Iba, Zambales and off the coast of kalibo, Aklan, according to Benison Estareja, a Pagasa weather expert.
Mr. Estareja said that the low pressure area off the Zambales may exit the Philippine Area of Responsibility (PAR) within 24 hours.
In addition, the low pressure area off the coast of Aklan will only move within the Visayas region before gradually dissipating, but it will cause rain before weakening.
While the low pressure area is unlikely to develop into a tropical storm, it is still expected to bring rain to most of southern Luzon and the Visayas, Estareja said in Pagasas weather forecast.
The depression will only remain in the Visayas and Mimaropa regions (including Occidental Mindoro, Oriental Mindoro, Marinduque, Romblon, Palawan) until it weakens by noon or tomorrow afternoon (May 8), he added.
Although the impact of the low pressure on Vietnam's sea weather is not yet clear, people and tourists should pay attention to the weather forecast for the night of May 7 and 8.
