Wide stretches of the Philippines face flash flood and landslide risks on Monday, June 29, 2026, as a Low Pressure Area (LPA) east of Surigao and the Southwest Monsoon combine to bring scattered to at times heavy rains across the Visayas, Bicol Region, Caraga, and parts of Luzon and MIMAROPA, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA). The agency released its 24-hour public weather forecast at 4:00 AM today, valid until 4:00 AM on June 30.
Even areas not directly in the path of the two active weather systems — including Metro Manila and the rest of the country — are not entirely in the clear, with localized thunderstorms capable of triggering flash floods during their most intense moments.
What Is Driving Today's Weather
Two distinct weather systems are at work across the archipelago today.
The first is a Low Pressure Area, which PAGASA estimated at 3:00 AM to be located 495 kilometers east of Surigao City, Surigao del Norte, at coordinates 10.0°N, 130.0°E. A Low Pressure Area is a region of the atmosphere where air pressure is lower than its surroundings, causing warm, moist air to rise and condense into clouds and rain. While an LPA is not yet a tropical cyclone and currently carries no wind signals, it can still generate significant rainfall and rough seas over nearby areas — in this case, the eastern Visayas, Caraga, and surrounding regions.
The second system is the Southwest Monsoon, locally known as habagat. PAGASA says it is currently affecting the western section of Southern Luzon. The habagat is a seasonal wind pattern that draws moisture-laden air from the southwestern seas into the country, typically from June through September. It is responsible for the wet, overcast conditions being experienced along the western coast of Southern Luzon and MIMAROPA today.
Region-by-Region Forecast
Visayas, Bicol Region, Caraga, Quezon, Oriental Mindoro, Marinduque, and Romblon
These areas will bear the brunt of today's weather. PAGASA forecasts cloudy skies with scattered rains and thunderstorms driven by the Low Pressure Area. Residents and local government units in these provinces should be on heightened alert for possible flash floods and landslides resulting from moderate to at times heavy rainfall. This includes all provinces of the Eastern Visayas, Central Visayas, Western Visayas, the Bicol Region, Caraga, as well as Quezon province in Luzon, and the island provinces of Oriental Mindoro, Marinduque, and Romblon.
The Rest of MIMAROPA (Occidental Mindoro, Palawan, and Mindoro islands)
The remaining provinces of the MIMAROPA region — those not already listed above — will experience cloudy skies with scattered rains and thunderstorms, this time driven by the Southwest Monsoon rather than the LPA. The hazard profile is the same: flash floods and landslides are possible where moderate to heavy rain falls, particularly in mountainous and coastal-adjacent communities.
Metro Manila and the Rest of the Country
The National Capital Region and all other areas not specifically mentioned above — including the rest of Luzon and Mindanao — can expect partly cloudy to cloudy skies with isolated rainshowers or thunderstorms. These will be driven by localized thunderstorm activity rather than a large-scale weather system. While conditions are generally less severe, PAGASA notes that flash floods and landslides remain possible during particularly intense thunderstorm episodes. Residents in low-lying or flood-prone areas should not be complacent.
Wind and Coastal Water Conditions
Winds across the country are described by PAGASA as light to moderate in intensity, with directions varying by region:
- Visayas and eastern Mindanao: Northeast to northwest winds; slight to moderate seas with wave heights of 0.6 to 1.5 meters.
- Western Luzon: Southwest to south winds; slight to moderate seas with wave heights of 0.6 to 1.2 meters.
- Rest of Luzon: East to southeast winds; slight to moderate seas with wave heights of 0.6 to 1.2 meters.
- Rest of Mindanao: Southwest to west winds; slight to moderate seas with wave heights of 0.6 to 1.2 meters.
No gale warnings have been issued by PAGASA for any sea area as of this bulletin. However, wave heights of up to 1.5 meters in the Visayas and eastern Mindanao are considered slight to moderate and can still pose risks to very small watercraft.
Decoding the Warnings: What Each Hazard Means for You
PAGASA has not raised any Tropical Cyclone Wind Signal for any part of the country today, as the LPA has not yet developed into a tropical cyclone. There are also no active color-coded rainfall warnings in this particular forecast bulletin. However, the agency explicitly flags possible flash floods and landslides as hazards for the areas affected by the LPA and the Southwest Monsoon — a consequence of sustained moderate to at times heavy rainfall over vulnerable terrain.
Flash flood risk means that low-lying communities near rivers, creeks, and drainage systems could experience rapidly rising water with little warning, especially during peak rainfall hours. Landslide risk applies to communities on or near slopes, hillsides, and mountainous terrain — a description that fits many barangays in Bicol, Caraga, the Visayas, and MIMAROPA.
If you are unsure how PAGASA's various warning systems — from rainfall color codes to storm signals — apply to your situation, this guide explains how to read PAGASA's weather warnings in plain language.
What Today's Weather Means for You
Commuters
In Metro Manila and other urban centers, isolated thunderstorms can develop quickly during the day and cause localized flooding on roads and underpasses. Allow extra travel time, particularly during afternoon hours when thunderstorm activity typically peaks. Avoid wading through floodwaters of unknown depth.
Fisherfolk and Small-Boat Operators
While no gale warnings are in effect, wave heights of up to 1.5 meters in the Visayas and eastern Mindanao — waters closest to the LPA — are a concern for small bangka and motorized outrigger operators. PAGASA advises caution on coastal waters across the board today. Those operating near the LPA's influence zone in the eastern Visayas and Caraga coastlines should closely monitor sea conditions before heading out and consider postponing trips if weather deteriorates.
Farmers and Agricultural Workers
The scattered to heavy rains across the Visayas, Bicol, Caraga, and MIMAROPA today may benefit crops in need of irrigation but also risk flooding of low-lying farmlands and the washing away of newly planted crops. Farmers in rain-affected provinces should secure loose materials, check irrigation canals and drainage ditches, and avoid farm work in areas prone to flash flooding during peak rainfall.
Students, Parents, and Schools
Parents in the Visayas, Bicol Region, Caraga, Quezon, Oriental Mindoro, Marinduque, and Romblon should monitor local government announcements on class suspensions, as the potential for moderate to heavy rains and flash floods in these areas may prompt local officials to act. Schools near riverbanks or flood-prone zones should be particularly attentive. Even in Metro Manila, sudden thunderstorms can disrupt afternoon dismissal schedules.
Outdoor and Construction Workers
Workers in outdoor and elevated settings — particularly in the heavily rain-affected provinces under LPA and habagat influence — should be aware of the landslide risk flagged by PAGASA. Hillside construction sites, quarrying areas, and workers near slopes in Bicol, Caraga, and the Visayas face elevated hazard today. Seek shelter during thunderstorms and do not attempt to traverse flooded or unstable terrain.
Temperature and Humidity Outlook
PAGASA's weather station at the Science Garden in Diliman, Quezon City recorded a maximum temperature of 33.6°C at 3:00 PM yesterday and a minimum of 25.5°C at 6:00 AM yesterday. Relative humidity ranged from a high of 91 percent to a low of 54 percent over the same 24-hour period. No heat index warning has been issued for today's bulletin. However, the combination of afternoon temperatures in the low 30s Celsius and high humidity typical of the wet season can still feel oppressive during dry spells between rain events, particularly in urban areas.
Sunrise over Metro Manila today is at 5:30 AM and sunset at 6:29 PM. The moon is at 100 percent illumination — a full moon — rising at 6:04 PM and setting at 4:32 AM tomorrow. High tide in Manila Bay is expected at 8:55 AM (1.26 meters), with a low tide at 6:01 PM (-0.08 meters), according to tidal predictions courtesy of NAMRIA.
Bottom Line
If you live in the Visayas, Bicol Region, Caraga, Quezon, Oriental Mindoro, Marinduque, Romblon, or MIMAROPA, today's scattered to at times heavy rains driven by the LPA and the Southwest Monsoon make flash floods and landslides your most immediate concern — stay away from riverbanks, slopes, and flood-prone areas, and keep emergency contacts ready. Everywhere else in the country, be ready for sudden thunderstorms that can briefly but intensely disrupt your day.
