MANILA, Philippines — Parts of the Philippines are in for a wet and stormy Wednesday as PAGASA's 4:00 AM forecast for November 4, 2026 warns of scattered rains and thunderstorms across several regions, with the Bicol Region facing the greatest risk of flash floods and landslides today. Residents and travelers in affected areas are urged to stay alert throughout the day.
What Is Driving Today's Weather
Two weather systems are shaping conditions across the country on November 4, according to PAGASA.
The northeast monsoon, known locally as the amihan, is currently affecting Northern Luzon. The amihan is a seasonal wind pattern that brings cooler, drier air flowing from the northeast — in areas it directly influences, it typically produces only light rain or partly cloudy conditions rather than heavy downpours.
The easterlies — moisture-laden winds blowing in from the Pacific Ocean — are the main driver of rain for the rest of the country today. As these winds push against land, they force warm, humid air upward, triggering cloud formation, rainshowers, and in some cases, intense thunderstorms. The Bicol Region, Metro Manila, the rest of Luzon, the Visayas, and Mindanao are all under their influence today.
PAGASA also notes that Typhoon In-Fa (2631) is currently located 1,770 kilometers east-northeast of extreme Northern Luzon, at coordinates 23.9°N, 138.7°E, as of 3:00 AM today. The typhoon is outside the Philippine Area of Responsibility (PAR) and is not directly affecting the country's weather at this time. It is packing maximum sustained winds of 130 km/h near its center and gusts of up to 160 km/h, moving north-northwestward at 10 km/h.
Region-by-Region Forecast: November 4, 2026
Bicol Region (Quezon, Camarines Norte, Camarines Sur, Catanduanes)
Residents in the Bicol Region face the most hazardous weather conditions in the country today. PAGASA expects cloudy skies with scattered rains and thunderstorms over Quezon, Camarines Norte, Camarines Sur, and Catanduanes, driven by the easterlies. The forecast warns of moderate to at times heavy rainfall, with flash floods and landslides as specific hazards. People living near rivers, low-lying areas, and hillsides in these provinces should be on alert and prepared to move to higher ground if necessary.
Northern Luzon: Ilocos Region, Cordillera Administrative Region, Cagayan Valley
These areas in Northern Luzon will have the calmest weather today, courtesy of the northeast monsoon. PAGASA forecasts partly cloudy to cloudy skies with isolated light rains. No significant weather impact is expected for the Ilocos Region, the Cordillera Administrative Region, and Cagayan Valley.
Metro Manila and the Rest of Luzon
Metro Manila and the remaining provinces of Luzon not covered above will experience partly cloudy to cloudy skies with isolated rainshowers or thunderstorms, brought about by the easterlies. While conditions may not be as persistently wet as in Bicol, PAGASA warns that flash floods and landslides remain possible during severe thunderstorms. Residents and commuters should keep a close eye on the sky and be ready for sudden, intense downpours.
Visayas
The Visayas will also feel the influence of the easterlies on Wednesday, with partly cloudy to cloudy skies and isolated rainshowers or thunderstorms expected across the region. As with the rest of Luzon, flash floods and landslides are possible during severe thunderstorms. Residents in low-lying coastal and inland areas of the Visayas should remain cautious, particularly during the afternoon when thunderstorm activity tends to peak.
Mindanao
Mindanao will experience partly cloudy to cloudy skies with isolated rainshowers or thunderstorms, produced by localized thunderstorm activity. PAGASA similarly flags flash floods and landslides as potential hazards during severe thunderstorms for this region.
Decoding the Warnings: What PAGASA Is Telling You
PAGASA's forecast for today does not carry any tropical cyclone wind signals, as Typhoon In-Fa remains well outside the Philippine Area of Responsibility. However, the hazard language in the forecast — specifically the mention of flash floods and landslides as possible impacts — deserves attention.
When PAGASA warns of possible flash floods or landslides due to moderate to at times heavy rainfall, as it does today for the Bicol Region, it means that rainfall could accumulate quickly enough to overwhelm drainage systems, cause rivers to overflow their banks, or destabilize slopes. These hazards can develop with little warning, particularly during thunderstorms.
For areas under isolated rainshowers or thunderstorms — Metro Manila, the rest of Luzon, the Visayas, and Mindanao — the flash flood and landslide risk is conditional: it applies specifically when thunderstorms become severe. This means the threat is real but not guaranteed for every location in those regions.

What Today's Weather Means for You
Commuters
If you are commuting in Metro Manila, the Visayas, or any part of Luzon today, be prepared for sudden downpours that can quickly flood streets and slow traffic. Bring a rain jacket or umbrella. Allow extra travel time, particularly during the afternoon and evening when thunderstorms are more likely to develop. In Bicol, commuting between provinces should be approached with caution given the forecast for scattered rains and the risk of flash floods on roads.
Fisherfolk and Small Boat Operators
PAGASA forecasts light to moderate winds blowing from the northeast to east over Luzon, Visayas, and Mindanao, with slight to moderate coastal waters. Wave heights of 0.6 to 2.5 meters are expected over Luzon and Visayas, and 0.6 to 1.8 meters over Mindanao. While these conditions are not the most severe, small boat operators should still exercise caution at sea, especially with thunderstorm activity possible. Check local conditions before heading out and do not venture out if weather deteriorates.
Farmers
Farmers in the Bicol Region should be particularly watchful today, as moderate to at times heavy rains increase the risk of flooding in low-lying agricultural areas. Secure equipment and livestock where possible. Farmers in Northern Luzon — Ilocos, Cordillera, and Cagayan Valley — face a more favorable day with only light and isolated rains forecast.
Students, Parents, and School Officials
Classes and school activities in the Bicol Region may be disrupted by heavy rain and the risk of flash floods. Parents and school administrators in Quezon, Camarines Norte, Camarines Sur, and Catanduanes should monitor PAGASA updates and local government announcements throughout the morning. In Metro Manila and the Visayas, isolated thunderstorms could cause brief disruptions, but widespread class suspensions are not indicated by the current forecast.
Outdoor Workers
Construction workers, delivery personnel, and others working outdoors across the country should be prepared for rain today. Those in the Bicol Region face the highest risk and should have contingency plans in the event of heavy downpours or flooding. In all other regions, the risk of severe thunderstorms developing means that outdoor workers should monitor conditions closely and seek shelter quickly if lightning or heavy rain begins.
Temperature Outlook
PAGASA recorded the following temperature extremes at the Science Garden weather station in Diliman, Quezon City, for the 24-hour period ending at 8:00 PM on November 3:
- Maximum temperature: 32.9°C (recorded at 2:00 PM)
- Minimum temperature: 25.5°C (recorded at 7:50 AM)
- Maximum relative humidity: 95% (recorded at 7:50 AM)
- Minimum relative humidity: 53% (recorded at 2:00 PM)
These figures reflect conditions at the Science Garden station and serve as a reference point for Metro Manila.
Tidal Information for Metro Manila
For reference, PAGASA — through data courtesy of NAMRIA — reports the following tidal predictions for Metro Manila today, November 4:
- High tide: 4:56 AM at 0.93 meters
- Low tide: 1:23 PM at 0.01 meters
- High tide: 8:58 PM at 0.52 meters
Sunrise is at 5:52 AM and sunset at 5:27 PM. The moon rises at 1:22 AM and sets at 1:59 PM, with a lunar illumination of 23%.
Bottom line: If you are in the Bicol Region today — particularly in Quezon, Camarines Norte, Camarines Sur, or Catanduanes — stay alert for flash floods and landslides as scattered rains and thunderstorms are forecast throughout the day. Avoid low-lying areas and riverbanks, and follow guidance from local disaster risk reduction offices. Everywhere else in the country, keep an umbrella handy and watch for sudden, intense thunderstorms that could cause localized flooding.
