QUEZON CITY, June 30, 2026 — A Low Pressure Area hovering near the coastal waters of Masbate is making itself felt across a wide stretch of the country this Tuesday, bringing scattered rains, thunderstorms, and the threat of flash floods to Metro Manila, the Visayas, and several island provinces in Mimaropa and Bicol. For millions of Filipinos heading out for work, school, or daily errands, today calls for an umbrella — and a weather eye on rising water levels.
PAGASA issued its 24-hour public weather forecast at 4:00 AM on June 30, 2026, valid until 4:00 AM on Wednesday, July 1, 2026.
What Is Driving Today's Weather?
At 3:00 AM today, PAGASA estimated the Low Pressure Area (LPA) to be located over the coastal waters of San Pascual, Masbate, at coordinates 12.9°N, 123.0°E. An LPA is a region of the atmosphere where air pressure is lower than its surroundings, causing warm, moist air to rise and cool rapidly — a process that generates clouds, rain, and thunderstorms. Because the LPA is currently positioned near the central Philippines, its weather effects are being felt most strongly in areas closest to it: Metro Manila, the Visayas, Bicol, and the Mimaropa island provinces.
Separately, the Southwest Monsoon — locally known as habagat — is affecting Palawan. The habagat is a seasonal wind pattern that blows moisture-laden air from the southwest across the country during the wet season, fueling persistent and at times heavy rainfall over western-facing coasts and islands.
The rest of the Philippines is dealing with localized thunderstorms, which are weather events driven by heat and atmospheric instability rather than a large-scale weather system — but they can still produce intense, short-duration downpours capable of causing flash floods.
Region-by-Region Forecast
Metro Manila and Nearby Provinces (Luzon)
Metro Manila, CALABARZON (Cavite, Laguna, Batangas, Rizal, Quezon), the Bicol Region, Occidental Mindoro, Oriental Mindoro, Marinduque, and Romblon are all under the influence of the LPA today. PAGASA forecasts cloudy skies with scattered rains and thunderstorms across these areas. The agency warns that flash floods and landslides are possible due to moderate to heavy rainfall.
Winds over Southern Luzon are blowing from the southwest to west at light to moderate strength. Coastal wave heights in these waters are expected to reach 0.6 to 2.1 meters — described as slight to moderate.
The rest of Luzon — including northern regions such as Ilocos, Cagayan Valley, Cordillera, and Central Luzon — is forecast to have partly cloudy to cloudy skies with isolated rainshowers or thunderstorms driven by localized weather. Winds in these areas are blowing from the east to southeast at light to moderate intensity, with coastal waves also in the slight to moderate range (0.6 to 2.1 meters).
Palawan
Palawan is under a separate weather driver today: the Southwest Monsoon. PAGASA forecasts cloudy skies with scattered rains and thunderstorms for the province, with flash floods and landslides possible due to moderate to at times heavy rains. Residents in low-lying coastal areas and mountainous interior communities should be on alert.
Visayas
The Visayas — covering the Eastern, Central, and Western Visayas regions — are among the areas most directly affected by the LPA today. Expect cloudy skies with scattered rains and thunderstorms, with the risk of flash floods and landslides from moderate to heavy rainfall. Winds across these islands are blowing from the southwest to west at light to moderate strength, and coastal waters are in the slight to moderate range with wave heights of 0.6 to 2.1 meters.
Mindanao
Mindanao is not directly under the LPA's influence today, but the island group is not entirely spared. PAGASA forecasts partly cloudy to cloudy skies with isolated rainshowers or thunderstorms due to localized weather systems. While the overall weather is less severe than in Luzon and Visayas, flash floods and landslides remain possible during any severe thunderstorm episode. Winds over Mindanao are blowing from the south to southwest at light to moderate intensity, with coastal wave heights of 0.6 to 1.5 meters.
Decoding the Hazard Warnings
PAGASA has flagged flash floods and landslides as the primary hazards for today across multiple regions. These are not abstract risks — they are direct consequences of the moderate to heavy rainfall being produced by the LPA and the Southwest Monsoon.
Flash floods can occur with very little warning, especially in low-lying urban areas, near river banks, and in communities at the foot of hills or mountains. Landslides are a serious concern in elevated, mountainous areas with loose or water-saturated soil — a risk that applies to Bicol, parts of Visayas, and interior communities in Palawan and Mindoro.
No tropical cyclone wind signals are active as of this bulletin. However, residents in LPA-affected areas should remain alert to any escalation in PAGASA advisories throughout the day.

What Today's Weather Means for You
Commuters in Metro Manila and Urban Luzon
Expect traffic snarls and flooded streets during or after heavy rain bursts today. The LPA's scattered thunderstorms can dump large amounts of rain in a short time, overwhelming drainage systems in low-lying urban areas. Allow extra travel time, avoid flood-prone underpasses and roads, and monitor local government alerts before heading out. If you see rising water on roads, do not attempt to cross — turn back.
Fisherfolk and Small Boat Operators
Coastal waters across the country are in the slight to moderate wave range today: 0.6 to 2.1 meters over Southern Luzon and Visayas, and 0.6 to 1.5 meters over Mindanao. While these conditions are not at gale-warning levels, small and bancas should exercise caution, particularly in the waters near the LPA around Masbate and surrounding sea lanes. Conditions can deteriorate quickly near active thunderstorms. If you are a fisherfolk operating near the Visayas or Bicol coast, exercise extra vigilance today.
Farmers
Farmers in Bicol, the Visayas, and Mindoro should secure crops and farm structures ahead of possible moderate to heavy rain. Flash flooding in low-lying agricultural areas can damage standing crops and erode topsoil. Those in upland areas should watch for signs of soil saturation that may precede landslides.
Students, Parents, and School Officials
Metro Manila and other LPA-affected provinces face the possibility of intense rain episodes today. Parents should monitor local government unit (LGU) announcements on school suspensions. Students who commute should have rain gear ready and avoid walking near canals, drainage openings, or flooded streets.
Outdoor Workers and Construction Personnel
Those working outdoors in Metro Manila, Bicol, the Visayas, and Mindoro should be prepared to suspend operations during thunderstorm episodes. Lightning is a serious risk during active thunderstorm cells associated with the LPA. Seek sturdy shelter at the first sign of thunder and avoid open fields, tall trees, and metal structures during lightning activity.
Temperature Outlook
PAGASA recorded a maximum temperature of 32.4°C at 1:00 PM yesterday and a minimum of 25.8°C at 5:00 AM yesterday at their official weather station in Science Garden, Diliman, Quezon City. Relative humidity ranged from 63% to 90% over the same period — reflecting the muggy, moisture-laden conditions typical of the wet season. While cloud cover from the LPA may moderate temperatures slightly today compared to recent days, the combination of heat and humidity will still feel oppressive, particularly between rain episodes.
Sunrise over Metro Manila today is at 5:30 AM and sunset at 6:29 PM. The moon is at 100% illumination tonight — a full moon — rising at 6:53 PM and setting at 5:24 AM tomorrow, according to astronomical data provided by NAMRIA.
Bottom Line
If you are in Metro Manila, the Visayas, Bicol, Mindoro, Marinduque, Romblon, or Palawan today — stay alert for flash floods and landslides. The LPA near Masbate is producing scattered to moderate rains and thunderstorms across a wide area. Avoid flood-prone zones, keep an eye on PAGASA updates, and do not cross flooded roads or rivers.
