QUEZON CITY, October 15, 2026 — Large parts of the Philippines face rain, thunderstorms, and the risk of flash floods and landslides on Thursday, as the Intertropical Convergence Zone (ITCZ) bears down on the Visayas, Mindanao, and portions of Luzon, while northeasterly winds bring milder but still unsettled conditions to the north. PAGASA issued its 24-hour public weather forecast at 4:00 AM today, valid until 4:00 AM on Friday, October 16, 2026.
What Is Driving Today's Weather?
Two weather systems are shaping Thursday's conditions across the archipelago. The dominant force is the Intertropical Convergence Zone, or ITCZ — a broad belt near the equator where warm, moisture-laden air masses from the northern and southern hemispheres meet, rise, and produce heavy cloud cover, persistent rains, and thunderstorms. When the ITCZ stalls or lingers over a region, it can dump rainfall over an extended period, making flash floods and landslides a serious concern in low-lying areas and hilly terrain.
The second system is northeasterly windflow, a seasonal wind pattern blowing from the northeast that is influencing Northern and Central Luzon. This wind pattern generally brings drier, cooler air to the northern parts of the country, resulting in mostly partly cloudy skies with only light, isolated rains in those areas.
Additionally, PAGASA is tracking a Tropical Depression currently located 2,015 kilometers east of extreme Northern Luzon — well outside the Philippine Area of Responsibility (PAR). As of 3:00 AM today, it had maximum sustained winds of 45 km/h near the center and gustiness of up to 55 km/h, moving westward at 10 km/h. PAGASA has not placed any part of the country under a tropical cyclone wind signal, and this system is not directly affecting local weather at this time. Filipinos should continue monitoring for updates as it tracks westward.
Region-by-Region Forecast
Luzon
Bicol Region and Quezon Province are squarely in the ITCZ's path today, according to PAGASA. Residents there can expect cloudy skies with scattered rains and thunderstorms, with moderate to at times heavy rainfall raising the risk of flash floods and landslides. People living near rivers, drainage channels, or on hillside communities in these areas should be on alert and ready to act on evacuation advisories from local disaster risk reduction offices.
Metro Manila and the rest of Luzon — provinces not covered by the ITCZ forecast or the northern windflow — can expect partly cloudy to cloudy skies with isolated rainshowers or thunderstorms due to localized thunderstorm development. PAGASA warns that flash floods and landslides remain possible during severe thunderstorm episodes. Commuters and outdoor workers in the capital region and neighboring provinces should be prepared for sudden, intense downpours at any time of day.
Ilocos Region, the Cordillera Administrative Region (CAR), Cagayan Valley, and Central Luzon will have a comparatively calmer day. PAGASA forecasts partly cloudy to cloudy skies with isolated light rains under northeasterly windflow. No significant weather impact is expected in these areas, though residents should remain weather-aware given the broader unsettled pattern across the country.
Visayas
All areas of the Visayas are under ITCZ influence today. PAGASA forecasts cloudy skies with scattered rains and thunderstorms, driven by moderate to at times heavy rainfall. The hazards of flash floods and landslides apply across the entire island group. Residents of Eastern, Western, and Central Visayas — particularly those in coastal or upland communities — should exercise caution and keep lines of communication open with local authorities.
Mindanao
Mindanao is also largely under the ITCZ, with the forecast for cloudy skies, scattered rains, and thunderstorms carrying the same flash flood and landslide risks as the Visayas. The full breadth of the island — from the Zamboanga Peninsula to Davao, the Caraga region, BARMM, and Soccsksargen — should prepare for wet, stormy conditions throughout the day. PAGASA notes that Palawan, while geographically positioned between Luzon and Mindanao, is also affected by the ITCZ today and faces the same hazards.
Decoding the Warnings: What Each Hazard Means for You
PAGASA identifies flash floods and landslides as the primary hazard for ITCZ-affected areas today. Flash floods can develop within minutes after intense rainfall — especially in areas near rivers, streams, and esteros. Landslides are a risk in mountainous provinces and areas with steep slopes, including parts of Bicol, the Cordilleras, Caraga, and Davao de Oro.
No tropical cyclone wind signals have been raised anywhere in the country. No rainfall advisory colors (yellow, orange, or red) appear in the source forecast, but PAGASA's language of "moderate to at times heavy rains" in ITCZ-affected zones is a meaningful caution in itself. Understanding what each warning level triggers is essential for every Filipino household — you can learn more about how to read PAGASA's weather warnings for rainfall colors, storm signals, and heat index categories.
Always follow instructions from your Local Disaster Risk Reduction and Management Office (LDRRMO) and do not attempt to cross flooded roads or swollen rivers.
Wind and Coastal Water Conditions
PAGASA's wind and sea-state forecast paints a varied picture for the country's coastal areas:
- Extreme Northern Luzon: Moderate to strong winds from the northeast. Coastal waters are moderate to rough, with wave heights of 1.5 to 2.8 meters.
- The rest of Luzon: Light to moderate winds from the northeast to east. Coastal waters range from slight to moderate, with wave heights of 0.6 to 2.1 meters.
- Visayas and eastern Mindanao: Light to moderate winds from the northeast to northwest. Coastal waters are slight to moderate, with wave heights of 0.6 to 1.5 meters.
- The rest of Mindanao: Light to moderate variable winds. Coastal waters are slight to moderate, with wave heights of 0.6 to 1.2 meters.
What It Means for You
Commuters
If you are traveling in Metro Manila, Bicol, Visayas, or Mindanao, expect possible traffic disruptions from flooded roads and reduced visibility during thunderstorms. Leave earlier than usual, avoid underpasses during heavy rain, and check for road closure advisories from local government units before heading out.
Fisherfolk and Small-Boat Operators
Conditions are most hazardous off extreme Northern Luzon, where moderate to rough seas with waves reaching up to 2.8 meters make small-vessel operations dangerous. PAGASA strongly advises small-boat operators in this area to remain ashore. Those in other coastal areas — where seas are slight to moderate — should still exercise caution, monitor conditions closely, and avoid heading far offshore, especially in areas already experiencing thunderstorm activity from the ITCZ.
Farmers and Agricultural Workers
Farmers in Bicol, Quezon, Visayas, Mindanao, and Palawan should be alert to the risk of flooding in low-lying agricultural areas. Prolonged or heavy ITCZ-driven rainfall can damage standing crops and disrupt field work. Coordinate with your local agriculture office for guidance on protecting harvests and livestock.
Students, Parents, and Schools
Parents of schoolchildren in ITCZ-affected regions — particularly Bicol, the Visayas, and Mindanao — should stay updated on any class suspension announcements from their respective local government units. Schools in flash-flood-prone areas may issue early dismissals if conditions deteriorate rapidly during the school day. Have a family communication plan ready.
Outdoor Workers and Construction Teams
Workers scheduled for outdoor activities across ITCZ-affected areas should be briefed on site-level weather protocols. Thunderstorm activity poses a lightning risk to those working in open fields, at elevated sites, or on scaffolding. Supervisors should have clear criteria for suspending work during severe thunderstorm events.
Temperature Outlook
PAGASA recorded the following temperature and humidity readings at its weather station in Science Garden, Diliman, Quezon City, for the 24-hour period ending at 8:00 PM on October 14, 2026:
- Maximum temperature: 31.6°C (recorded at 1:00 PM)
- Minimum temperature: 25.5°C (recorded at 5:00 AM)
- Maximum relative humidity: 92% (recorded at 5:00 AM)
- Minimum relative humidity: 60% (recorded at 4:00 PM)
The high humidity readings are consistent with the widespread moisture being drawn in by the ITCZ and prevailing wind patterns. Residents in Metro Manila and surrounding areas should expect warm, muggy conditions, particularly during any dry spells between rain episodes.
Tides and Astronomical Information for Metro Manila
For reference, PAGASA — with courtesy to NAMRIA — reports the following for Manila Bay on October 15, 2026: a low tide of -0.05 meters at 7:54 AM. Sunrise is at 5:47 AM and sunset at 5:36 PM. The moon rises at 9:34 AM and sets at 8:54 PM, with a lunar illumination of 21%.
Bottom Line
If you live in or are traveling through the Visayas, Mindanao, Bicol Region, Quezon, or Palawan today, take the flash flood and landslide risk seriously — have an evacuation plan, keep emergency supplies ready, and follow your local government's advisories. Do not wait for conditions to worsen before acting.
