MANILA, Philippines — Tuesday, June 24, 2026 — A trough of a Low-Pressure Area (LPA) lurking off the eastern coast of the Visayas is sending clouds and rain across a broad swath of the Philippines today, with some areas at risk of localized flooding and landslides, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
PAGASA's 24-hour public weather forecast, issued at 1:00 AM and valid through early Wednesday, identifies several regions facing the brunt of today's wet weather — from the far north in Cagayan and Batanes, down through Eastern Visayas, across Palawan and Occidental Mindoro, and through much of Mindanao. Metro Manila and surrounding areas are not entirely spared, with afternoon and evening thunderstorms possible.
What Is Driving Today's Weather?
The principal weather maker today is the trough of a Low-Pressure Area affecting the eastern section of Visayas. In plain terms, a low-pressure area is a region of the atmosphere where air pressure is lower than its surroundings — warm, moisture-laden air rises from the ocean surface, cools as it climbs, and releases that moisture as rain and thunderstorms. A trough is essentially an elongated extension of that low-pressure system, and it can spread unsettled weather well beyond the center of the LPA itself, which is why regions as far away as Cagayan and Mindanao are feeling its effects today.
PAGASA has not yet elevated this system to a named tropical cyclone, but its presence is enough to generate organized cloudiness, scattered thunderstorms, and dangerous coastal conditions across a wide area of the archipelago.
Region-by-Region Forecast
Luzon
Residents in Cagayan and Batanes, the northernmost provinces of the country, should expect cloudy skies with scattered rain showers and thunderstorms today. The weather in these areas is being influenced by the same LPA trough, and localized flooding and landslides remain a concern — particularly in hilly and coastal communities in Batanes and along river systems in Cagayan Valley.
Palawan and Occidental Mindoro are also under the influence of the LPA trough, with cloudy skies and rain showers expected throughout the day. Residents in low-lying coastal barangays and those living near mountain slopes should remain cautious and ready to respond to any flooding or landslide warnings from local disaster risk reduction offices.
Metro Manila and the rest of Luzon will see partly cloudy to cloudy skies, with isolated rain showers or thunderstorms possible — most likely during the afternoon and evening hours. While conditions are not as severe as in the directly affected provinces, sudden heavy downpours can still cause localized flooding and traffic disruptions, particularly in flood-prone urban areas.
Visayas
Eastern Visayas bears the most direct impact today, being closest to the LPA trough. Residents in Samar, Eastern Samar, Northern Samar, and Leyte should prepare for cloudy skies, rain showers, and thunderstorms that may be heavy at times. Localized flooding and landslides are explicitly cited by PAGASA as risks for this region. Communities in mountainous interior areas and those along rivers and coastal zones face the greatest exposure.
The rest of the Visayas — Central Visayas and Western Visayas — may see partly cloudy to cloudy conditions with the possibility of isolated showers, though conditions there are generally less severe than in the eastern part of the region.
Mindanao
Large portions of Mindanao are also under cloudy skies with scattered rain showers and thunderstorms, driven by the LPA trough's reach across the southern Philippine Sea. PAGASA flags localized flooding and landslides as possible hazards for affected areas across the island group. Residents in mountainous provinces such as Bukidnon, Davao de Oro, Lanao del Norte, and other upland areas should be especially vigilant, as intense rain can trigger rapid landslides with little warning.
Coastal communities in Mindanao, particularly those facing the Pacific and the Celebes Sea, should also monitor sea conditions carefully today.
Decoding the Warnings: What Each Advisory Means for You
PAGASA has identified the risk of localized flooding and landslides for areas under the influence of the LPA trough — specifically Eastern Visayas, Cagayan, Batanes, Palawan, Occidental Mindoro, and Mindanao. This is not a casual footnote: it is PAGASA's way of telling residents and local governments in those areas that the rainfall forecast is intense enough to trigger these hazards, even without a formal rainfall warning color code being issued.
If your local government unit or barangay raises a flood or evacuation alert, follow it immediately. Do not wait for floodwaters to reach your doorstep before acting.

Winds and Coastal Water Conditions
PAGASA's forecast also covers wind and coastal sea conditions, which are significant today. Here is a plain-language breakdown of what mariners and coastal residents can expect:
The northern and eastern seaboards of the country — including the waters off the Pacific coast of Luzon and the Philippine Sea — are experiencing moderate to rough seas, with wave heights reaching levels that make navigation hazardous for small vessels. Winds in these areas are coming from the northeast to northwest direction.
Waters off western and southern Mindanao and parts of southern Luzon face slight to moderate seas, with winds from the southwest to northwest direction and wave heights ranging from 0.6 to 1.8 meters. While these conditions are less severe, small outrigger boats and bancas remain vulnerable.
The rest of the country's coastal waters are generally slight to moderate, with light to moderate winds. Conditions can change rapidly when thunderstorms develop, however, so all mariners should exercise caution.
What It Means for You
Commuters
If you are traveling through Metro Manila, Cagayan, Eastern Visayas, or Mindanao today, expect the possibility of heavy afternoon downpours that can cause flash flooding in low-lying streets and major thoroughfares. Allow extra travel time in the afternoon and evening, avoid underpasses and flood-prone roads during heavy rain, and check for local government advisories on road closures before heading out.
Fisherfolk and Small-Boat Operators
PAGASA's coastal water forecast indicates moderate to rough seas off the northern and eastern coasts of the country. Small boat operators — particularly those in Cagayan, Batanes, Eastern Visayas, and coastal Mindanao — are strongly advised not to venture out to sea today. Even in areas with slight to moderate seas, the rapid development of thunderstorms can dramatically worsen conditions with very little warning. Stay ashore until seas calm and PAGASA lifts any advisories.
Farmers
Rain in Eastern Visayas, Cagayan, Palawan, and Mindanao may bring some relief to dry crops, but the risk of flooding and landslides poses a danger to lowland rice fields and hillside farms. Farmers in these areas should secure loose equipment and be prepared to drain low-lying fields quickly if heavy rain persists. Those in landslide-prone upland farming areas should evacuate early if local authorities advise it.
Students, Parents, and School Administrators
Classes in areas directly affected by the LPA trough — particularly in Eastern Visayas, Cagayan, Batanes, Palawan, and parts of Mindanao — may be disrupted if local government units issue class suspension orders due to heavy rain or flooding. Parents should monitor local government announcements and keep children indoors during thunderstorms. Schools in at-risk areas should review their disaster preparedness and evacuation protocols today.
Outdoor Workers
Construction workers, utility linemen, delivery riders, and others who work outdoors in the affected regions should take shelter immediately when thunder or lightning is detected. PAGASA's forecast specifically mentions thunderstorms alongside rain, which means lightning risk is elevated. Employers in affected areas are encouraged to adjust work schedules or provide safe shelter arrangements for outdoor personnel.
Temperature and Humidity Outlook
PAGASA's weather station in Diliman, Quezon City recorded a maximum temperature of 34°C and a minimum of 25.5°C in the 24-hour period ending yesterday afternoon. Relative humidity ranged from a minimum of 60% (recorded at 3:00 PM) to a maximum of 95%. These figures reflect conditions at a single official monitoring station and may differ from those in other parts of the country, but they give an indication of the warm, humid baseline across the northern Philippines even as rain clouds gather.
The combination of high humidity and daytime warmth means that even in areas not directly under rain today, it will feel hot and muggy — particularly in the morning before clouds build and afternoon thunderstorms develop.
Bottom Line
If you live in Eastern Visayas, Cagayan, Batanes, Palawan, Occidental Mindoro, or Mindanao, the single most important thing you can do today is stay alert and know your evacuation route. The LPA trough is producing conditions that PAGASA says can trigger flash flooding and landslides. Do not dismiss heavy rain as routine. Watch for local government alerts, avoid flood-prone areas, and keep children and elderly family members safe indoors. For everyone else across the country, be ready for afternoon thunderstorms and carry rain gear wherever you go.
