LPA affecting Eastern Visayas, Caraga, Davao
MANILA, Philippines – State weather bureau PAGASA continues to monitor a low pressure area (LPA) as it heads for Mindanao.
In a bulletin issued 4 pm on Saturday, June 2, PAGASA said the LPA is located 315 kilometers east southeast of Surigao City, Surigao del Norte.
It is also embedded along the intertropical convergence zone (ITCZ), a belt near the equator where the trade winds of the Northern Hemisphere and Southern Hemisphere meet, usually causing LPAs or thunderstorms.
The LPA will trigger moderate to heavy rain in Eastern Visayas, Caraga, and Davao. Residents of these regions should be on alert for possible flash floods or landslides.
PAGASA also warned that the LPA could develop into a tropical depression within the next 24 to 48 hours. It would be given the local name Domeng if it becomes a tropical depression. (READ: LIST: PAGASA's names for tropical cyclones in 2018)
Aside from the LPA, the ITCZ itself will bring light to heavy rain to Mimaropa, Bicol, the rest of the Visayas, and the rest of Mindanao. Flash floods and landslides are also possible in these areas.
The rest of Luzon, including Metro Manila, will only have isolated rains or thunderstorms with "no significant impact."
Meanwhile, another LPA that PAGASA was previously monitoring, located off Palawan, has since exited the Philippine Area of Responsibility (PAR). It became a tropical depression outside PAR and does not pose a threat to the country.
PAGASA earlier said it might declare the official start of the rainy season between June 4 and 14.
For the onset of the rainy season to be declared, the requirement is 5 straight days of rain generating a total amount of at least 25 millimeters (mm) of rainfall. These 5 days must also include 3 straight days of at least 1 mm of rainfall. (READ: FAST FACTS: Tropical cyclones, rainfall advisories) – Rappler.com
