MANILA, Philippines — Monday, October 12, 2026: Most Filipinos across Luzon, Visayas, and Mindanao will wake up to cloudy skies and face a day of scattered to isolated rain and thunderstorms, according to PAGASA's 4:00 AM public weather forecast issued today. Flash floods and landslides are the primary hazards to watch, with several of the country's most densely populated areas — including Metro Manila — included in the affected zones.
Three separate weather systems are working simultaneously across the archipelago, ensuring that virtually no region escapes wet conditions entirely today.
What Is Driving Today's Weather
The dominant force across Southern Luzon, the Visayas, and Mindanao is the Intertropical Convergence Zone (ITCZ) — a broad belt near the equator where trade winds from the northern and southern hemispheres meet, forcing warm, moist air upward and triggering persistent cloud formation, heavy rain, and thunderstorms. When the ITCZ sits over or near the Philippines, it can produce prolonged and widespread rainfall across a large swath of the country.
Meanwhile, easterlies — steady winds blowing in from the Pacific Ocean — are bringing moisture-laden air into the eastern sections of Northern and Central Luzon, including Metro Manila and surrounding provinces. This wind pattern channels ocean moisture directly inland, fueling rain and thunderstorms across the most populated corridor of the country.
In the far north, northeasterly windflow — the early signature of the northeast monsoon, locally known as amihan — is influencing Batanes and the Babuyan Islands, bringing cloudy skies and rain to the country's northernmost communities.
Additionally, PAGASA reports a tropical depression located 3,030 kilometers east of Central Luzon (at coordinates 16.6°N, 150.5°E), with maximum sustained winds of 55 km/h near the center and gustiness of up to 70 km/h. The system is moving north-northwestward slowly and remains well outside the Philippine Area of Responsibility (PAR). It poses no direct threat to the country at this time, but PAGASA continues to monitor its track and intensity.
Region-by-Region Forecast
Luzon
Batanes and Babuyan Islands — the Philippines' northernmost communities — will experience cloudy skies with rain due to northeasterly windflow. Moderate to heavy rain is possible, raising the risk of flash floods and landslides in these island communities.
Metro Manila, CALABARZON (Cavite, Laguna, Batangas, Rizal, Quezon), Central Luzon, Isabela, Quirino, Nueva Vizcaya, Benguet, and Pangasinan are all under a forecast of cloudy skies with scattered rains and thunderstorms driven by the easterlies. Moderate to heavy rain is expected at times, and residents should be prepared for flash flooding in low-lying areas and landslides in elevated terrain.
Bicol Region and MIMAROPA (Mindoro, Marinduque, Romblon, Palawan) face some of the more serious conditions today. The ITCZ will bring cloudy skies with scattered rain and thunderstorms, with moderate to heavy rain expected. Flash floods and landslides are a clear hazard for communities in these areas, including Camarines Norte, Camarines Sur, Albay, Sorsogon, and the island provinces of MIMAROPA.
The rest of Luzon — areas not specifically named above — can expect partly cloudy to cloudy skies with isolated rainshowers or thunderstorms. Flash floods and landslides remain possible during severe thunderstorms, though conditions are expected to be less persistent than in the named areas.
Visayas
Much of the Visayas will feel the full force of the ITCZ today. Western Visayas, Negros Island Region, and Central Visayas are forecast to have cloudy skies with scattered rain and thunderstorms, carrying the risk of flash floods and landslides due to moderate to heavy rains. Residents of Iloilo, Bacolod, Cebu, and surrounding provinces should remain alert throughout the day.
Leyte and Southern Leyte face the same ITCZ-driven conditions — cloudy skies, scattered rain and thunderstorms — with flash flooding and landslides possible in areas prone to these hazards.
The rest of the Visayas will see partly cloudy to cloudy skies with isolated rainshowers or thunderstorms. Flash floods and landslides may still occur during the more intense thunderstorm episodes.
Mindanao
Caraga, Northern Mindanao, and Zamboanga Peninsula are directly in the ITCZ's path and will experience cloudy skies with scattered rain and thunderstorms. Moderate to heavy rain is forecast, with the risk of flash floods and landslides across these regions. Residents of Davao Oriental, Surigao del Norte, Misamis Oriental, and Zamboanga City should take particular caution.
The rest of Mindanao will have partly cloudy to cloudy skies with isolated rainshowers or thunderstorms. As with the rest of the country, severe thunderstorms can still trigger localized flash flooding and landslides even in areas with generally lighter forecast conditions.
Wind and Sea Conditions
Wind and wave conditions today vary by location:
- Northern Luzon, Central Luzon, and the western section of Southern Luzon: Moderate winds blowing from the northeast to east. Coastal waters will be moderate, with wave heights of 1.5 to 2.5 meters. Small vessel operators in these waters should exercise caution.
- Visayas and the rest of Luzon: Light to moderate winds from the east to southeast. Coastal waters will be slight to moderate, with wave heights of 0.6 to 1.8 meters.
- Mindanao: Light to moderate winds from the southwest to southeast. Coastal waters will also be slight to moderate, with wave heights of 0.6 to 1.8 meters.
Decoding Today's Hazard Warnings
PAGASA's forecast identifies flash floods and landslides as the primary hazards across most of the country today, tied directly to the rainfall from the ITCZ, easterlies, and northeasterly windflow. These are not abstract risks — they are the forecasted consequence of moderate to heavy rain falling in areas with rivers, drainage systems, and slopes that can overwhelm quickly.
No tropical cyclone wind signals are in effect, as the tropical depression in the Pacific remains far outside PAR. However, the combination of three active weather systems means that rain can intensify quickly and without much warning in localized areas, particularly during thunderstorms.

What It Means for You
Commuters
Metro Manila, CALABARZON, and Central Luzon commuters should expect rain during the morning and throughout the day. Flooding on low-lying roads and streets is possible during heavy downpours. Allow extra travel time, avoid underpasses and flood-prone corridors during peak rainfall, and keep emergency contacts ready. If driving, do not cross flooded roads regardless of water depth.
Fisherfolk and Small-Boat Operators
Moderate coastal waters with wave heights reaching up to 2.5 meters off Northern and Central Luzon present real challenges for small and medium fishing vessels. PAGASA advises caution in these waters. Fisherfolk in the Visayas and Mindanao face slight to moderate seas (up to 1.8 meters), which are more manageable but still require attention. All mariners should check conditions before heading out and be prepared to return to port quickly if the weather deteriorates.
Farmers
The scattered to widespread rainfall across the country today can be beneficial for crops, but heavy downpours in Bicol, Leyte, Caraga, and Northern Mindanao raise the risk of flash flooding that can inundate low-lying farmland. Farmers in hilly and mountainous areas across all three island groups should be alert to landslide risks on slopes. Secure equipment and livestock before thunderstorms develop.
Students, Parents, and School Administrators
With thunderstorms forecast across most regions, parents and school administrators should monitor local government announcements on class suspensions, particularly in Bicol, the Visayas, and Mindanao where ITCZ-driven rain is expected to be heaviest. Students commuting to school should bring rain gear and avoid walking through flooded streets.
Outdoor Workers and Construction Personnel
Construction sites, outdoor markets, and agricultural work sites across virtually all regions face the risk of sudden, intense thunderstorms today. Workers should have a clear plan for shelter when lightning is observed or thunder is heard, and supervisors should assess whether it is safe to continue outdoor operations throughout the day.
Temperature Outlook
PAGASA's weather station at Science Garden in Diliman, Quezon City recorded temperatures for the 24-hour period ending at 8:00 PM yesterday: a maximum of 29.1°C (recorded at 11:00 AM) and a minimum of 25.7°C (recorded at 5:00 AM). Relative humidity peaked at 95% at 8:00 AM and dipped to a minimum of 76% at 11:00 AM. The high humidity combined with cloud cover and rainfall will make conditions feel muggy and oppressive in many areas today, even when rain is not actively falling.
Bottom line: Rain, thunderstorms, and the risk of flash floods and landslides touch virtually every region of the Philippines today, October 12, 2026. Whether you are in Metro Manila, the Bicol Peninsula, the Visayas, or Mindanao — stay away from rivers, esteros, and hillsides during heavy rain, and do not wait for floodwaters to rise before moving to higher ground. The safest action is to shelter in place during thunderstorms and to monitor your local government's announcements throughout the day.
