The shear line and the intertropical convergence zone (ITCZ) are bringing rain to several areas in the Philippines, as the state weather bureau continues to monitor a low-pressure area (LPA) inside the Philippine Area of Responsibility.
The LPA was located 820 kilometers east of Eastern Visayas on Tuesday morning, still too far to affect the country, the Philippine Atmospheric, Geophysical and Astronomical Services Administration said Tuesday.
PAGASA said the LPA may develop into a tropical depression that would be called “Paeng” within 72 hours — the country’s 16th tropical cyclone for the year and the fourth for October.
The shear line is the point where warm air and cold air converge, while the ITCZ is a belt near the equator where the trade winds of the Northern Hemisphere and Southern Hemisphere meet.
In an advisory at 11 am on Tuesday, PAGASA said moderate to heavy rain, with at times intense rain, was hitting Aurora, Quezon, and Eastern Visayas.
Light to moderate rain, with at times heavy rain fell over Cagayan, Isabela, Apayao, the rest of Central Luzon, Metro Manila, Rizal, Laguna, Central Visayas, Caraga, and Northern Mindanao.
PAGASA warned that floods and landslides are likely in these areas.
