MANILA, Philippines – The intertropical convergence zone (ITCZ) is affecting the southern part of Mindanao, while the tail-end of a cold front (TECF) is affecting the southern part of Luzon.
The ITCZ is a belt near the equator where the trade winds of the Northern Hemisphere and Southern Hemisphere meet, causing thunderstorms.
The TECF, meanwhile, is an “extended zone of converging winds from east to northeast that often brings thunderstorms and rainshowers,” according to the state weather bureau.
In a bulletin issued 4 pm on Thursday, January 2, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said the following areas will have scattered rain and thunderstorms within the next 24 hours due to the ITCZ:
- Davao Region
Similar conditions will persist in the areas below on Friday, January 3, this time due to the TECF:
- Oriental Mindoro
- southern part of Quezon
For areas affected by both the ITCZ and the TECF, PAGASA warned that flash floods and landslides are possible in high-risk zones.
There will also be scattered light rain due to the northeast monsoon or hanging amihan in the following areas:
- Cagayan Valley
- Mountain Province
- northern part of Quezon
The rest of Luzon, including Metro Manila, will only have isolated light rain, still due to the northeast monsoon.
Palawan, the Visayas, and the rest of Mindanao will enjoy generally fair weather, with only isolated rainshowers or localized thunderstorms.
PAGASA Weather Specialist Aldczar Aurelio said there is no low pressure area or tropical cyclone being monitored, whether inside or outside the Philippine Area of Responsibility.
The Philippines gets an average of 20 tropical cyclones per year. (READ: FAST FACTS: Tropical cyclones, rainfall advisories) – Rappler.com
