The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) yesterday spotted a shallow low-pressure area (SLPA) near the Bicol region, which is expected to bring rains in Southern Luzon, including Metro Manila; Visayas, and Mindanao this week.
PAGASA Weather Specialist 2 Nonoy About said the SLPA is expected to bring rains over Southern Luzon, including Metro Manila; Visayas, and Mindanao starting today. He said that residents in the Visayas must expect widespread rains in their area.
About explained that the SLPA, embedded along the weather system Intertropical Convergence Zone (ITCZ), will cause widespread downpour in the Visayas. The ITCZ is a known breeding ground of tropical cyclones.
The SLPA was initially spotted by the weather bureau at 480 kilometers (kms) east of Catanduanes.
About said residents in Central and Northern Luzon can expect good weather in the next few days.
However, rains are expected in the two areas later this week as the SLPA moves toward Luzon.
About said that the SLPA has a chance of developing into an active low pressure area (ALPA) in the next four days.
This, he said, is due to the sea surface temperature (SST) east of Central and Northern Luzon, where the SLPA is expected to track, which is favorable to cyclonic circulation.
Once the SLPA develops into a tropical cyclone, it will be locally named "Marce," to signify its entry as the 13th tropical cyclone in the country this year. It will also be the first tropical cyclone for the month of September.
