The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (Pagasa) has issued its detailed weather forecast for December 22, 2024, highlighting the effects of the Shear Line and the Northeast Monsoon across the country. Meanwhile, a tropical depression outside the Philippine Area of Responsibility (PAR) is being monitored closely.
Tropical Depression Update
As of 3:00 AM today, a tropical depression is located 620 kilometers south of Kalayaan, Palawan, at coordinates 5.5°N, 114.3°E. It has maximum sustained winds of 55 km/h with gusts reaching 70 km/h. The system is moving north-northeastward at 20 km/h.
Weather Conditions Across Regions
Southern Luzon, Visayas, and Dinagat Islands:
The Shear Line brings cloudy skies, scattered rains, and isolated thunderstorms to the Bicol Region, CALABARZON, Mindoro provinces, Marinduque, Romblon, and the Visayas. Residents should prepare for possible flash floods and landslides, especially in areas prone to moderate to heavy rains.
Zamboanga Peninsula, Palawan, and Sulu Archipelago:
The trough of the tropical depression is causing cloudy skies with scattered rains and thunderstorms. This may lead to flash floods or landslides in areas experiencing moderate to heavy rainfall.
Metro Manila, Cagayan Valley, Cordillera Administrative Region, and Central Luzon:
The Northeast Monsoon is expected to bring cloudy skies and rain. Moderate to heavy rainfall may result in localized flooding or landslides, especially in low-lying and mountainous areas.
Rest of Luzon:
Partly cloudy to cloudy skies with isolated light rains are expected due to the Northeast Monsoon. No significant impacts are anticipated.
Rest of Mindanao:
Partly cloudy to cloudy skies with isolated rain showers or thunderstorms are expected, influenced by the tropical depression’s trough. Severe thunderstorms may trigger flash floods or landslides in some areas.
Coastal Water and Wind Conditions
Northern Luzon and Eastern Sections of Central and Southern Luzon:
Expect strong northeast winds with rough coastal waters ranging from 2.8 to 4.5 meters.
Visayas, Rest of Luzon, and Northeastern Mindanao:
Moderate to strong winds from the northeast to east will create moderate to rough coastal waters, with wave heights from 1.5 to 3.7 meters.
Rest of Mindanao:
Light to moderate winds from the east to southeast will result in slight to moderate seas, with wave heights ranging from 0.6 to 2.5 meters.
Rainfall Outlook
Today:
- Intense to torrential rains (>200 mm) in Kalayaan Islands.
- Heavy to intense rains (100-200 mm) in Quezon, Camarines Norte, and Palawan.

Flood Advisories
Flood advisories have been issued for several regions, including MIMAROPA, Bicol, Central Visayas, Eastern Visayas, and Zamboanga Peninsula. Residents in affected areas are urged to take precautionary measures.
Pagasa advises continuous monitoring of updates, particularly in areas under the influence of the Shear Line and the tropical depression’s trough.
