QUEZON CITY, August 1, 2026 — A Low Pressure Area (LPA) lurking nearly a thousand kilometers off the eastern coast of Luzon is the main weather story for Filipinos this Saturday, pushing scattered rains, thunderstorms, and the threat of flash floods and landslides into several parts of the country. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) released the forecast at 4:00 AM today, valid until 4:00 AM on Sunday, August 2, 2026.
While much of the Philippines will see only isolated showers, communities in the Bicol Region, Eastern Visayas, Central Visayas, the province of Quezon, and Marinduque face a more serious weather situation today — one that demands caution from residents, local officials, and anyone planning to travel or work outdoors.
What Is Driving Today's Weather?
At 3:00 AM this morning, PAGASA estimated the Low Pressure Area at coordinates 14.8°N, 130.6°E — roughly 960 kilometers east of Southeastern Luzon. A Low Pressure Area is a zone of the atmosphere where warm air rises and converges, creating cloudy, unsettled weather. It is not yet a tropical cyclone, but the circulation and moisture it draws in are enough to produce sustained and at times heavy rainfall over a wide area. The trough — or the elongated extension — of this LPA is what is directly affecting the eastern and central parts of the country today.
For the rest of the Philippines, localized thunderstorms, the kind that develop from afternoon heat and humidity rather than from a large weather system, are the main concern. These storms can be brief but intense, and they can produce dangerous flash flooding even in areas not directly under the LPA's influence.
Region-by-Region Forecast
Bicol Region, Eastern Visayas, Central Visayas, Quezon, and Marinduque
These areas are directly in the path of the LPA's trough and will bear the brunt of today's weather. PAGASA forecasts cloudy skies with scattered rains and thunderstorms throughout the forecast period. Rainfall intensity is described as moderate to at times heavy, and the agency explicitly warns of possible flash floods and landslides.
Residents in low-lying areas along rivers and those living on hillsides or in mountainous communities across Bicol, Leyte, Samar, Cebu, Bohol, and the island provinces of Quezon and Marinduque should be on heightened alert. This is not the day for a casual hike or river crossing. If your barangay is prone to flooding, identify your nearest evacuation center and monitor your local government's announcements closely.
Metro Manila and the Rest of the Country
The national capital region and all remaining provinces across Luzon, Visayas, and Mindanao not listed above can expect partly cloudy to cloudy skies with isolated rain showers or thunderstorms. The driver here is localized convection — essentially, afternoon thunderstorms that build up from heat. While this is less alarming than the LPA-driven rain in the east, PAGASA still warns that flash floods and landslides are possible wherever severe thunderstorms develop.
Metro Manila commuters and residents should prepare for the typical afternoon shower season pattern: mornings may be relatively calm, but conditions can deteriorate quickly in the early afternoon. Keep an umbrella and monitor weather updates before heading out for errands or travel.
Mindanao
Mindanao falls under the general category of areas expecting partly cloudy to cloudy skies with isolated showers or thunderstorms due to localized weather disturbances. The same caution about flash floods during severe thunderstorms applies here. No special weather system is directly targeting Mindanao today based on PAGASA's 4:00 AM forecast.
Wind and Coastal Water Conditions
PAGASA also issued the following wind and wave forecasts for today's maritime conditions:
Over Mindanao: Winds are light to moderate, blowing from the south to southwest. Coastal waters are slight to moderate, with wave heights of 0.6 to 1.8 meters.
Over Luzon and Visayas: Winds are light to moderate, coming from the northeast to northwest. Wave heights are slight to moderate, ranging from 0.6 to 1.2 meters.
No gale warning has been raised as of this forecast issuance. However, fisherfolk and small boat operators — particularly those off the eastern coasts of Luzon and Visayas — are reminded that conditions can change rapidly when an LPA is active nearby. The sea may appear manageable in the morning but can become rough quickly as weather systems evolve.
Decoding the Warnings: What PAGASA's Hazard Flags Mean for You
PAGASA's forecast for the Bicol Region, Eastern Visayas, Central Visayas, Quezon, and Marinduque includes an explicit warning of possible flash floods or landslides due to moderate to heavy rainfall. This is not a routine advisory — it means water can rise very quickly in low-lying areas and that hillsides already saturated by previous rains are vulnerable to giving way with little warning.
Flash floods can occur within minutes of heavy rainfall, especially in urban areas with poor drainage and in narrow river valleys. Landslides can happen on slopes, roads carved into mountains, and communities built near cliffs or embankments.

No tropical cyclone wind signals have been raised as of this bulletin. The LPA has not developed into a named storm.
What Today's Weather Means for You
Commuters
In Metro Manila and other major urban centers, expect possible traffic disruptions in the afternoon as localized thunderstorms roll in. Roads in flood-prone areas — particularly in low-lying districts of Metro Manila, Naga, Legazpi, Tacloban, and Cebu City — may experience surface flooding. Leave earlier than usual if you are traveling, and avoid underpasses and low-lying roads if rain becomes heavy.
Fisherfolk and Small-Boat Operators
Fishing communities along the eastern seaboard of Luzon and Visayas — from Quezon province down through Bicol to Samar and Leyte — face the most uncertain sea conditions today. While no gale warning is in effect, the LPA's proximity means conditions can shift rapidly. PAGASA advises caution. Small boats and bancas should consider staying in port, especially along the eastern coasts, until the LPA's track becomes clearer.
Farmers
Farmers in the Bicol Region and Eastern and Central Visayas should take precautions to protect standing crops and low-lying fields from potential flooding and soil erosion. Those in the rest of the country should watch for brief but intense afternoon downpours that could damage newly planted or harvested crops. Secure equipment and cover harvested grain if stored outdoors.
Students, Parents, and Schools
Parents sending children to school today — particularly in Bicol, Eastern Visayas, and the Quezon-Marinduque corridor — should keep a close eye on local government suspension announcements, especially if heavy rain begins in the morning. Local chief executives are authorized to call class suspensions based on local conditions. Even in Metro Manila, afternoon dismissal could coincide with thunderstorms, so prepare for children to need pickup or shelter.
Outdoor Workers
Construction workers, delivery riders, vendors, and others working outdoors — particularly in areas directly affected by the LPA trough — face a challenging day. If you work in or near Bicol or the Visayas, plan around the likelihood of sustained and heavy rain. Seek shelter at the first sign of lightning; do not wait for the storm to worsen before getting indoors.
Temperature and Humidity Outlook
PAGASA's weather station at the Science Garden in Diliman, Quezon City recorded a maximum temperature of 32.1°C at 2:00 PM yesterday and a minimum temperature of 25.2°C at 5:00 AM. Relative humidity ranged from a high of 91 percent to a low of 63 percent over the same 24-hour period ending at 8:00 PM on July 31.
With cloud cover and rain expected to dominate much of the day, temperatures in affected areas may feel somewhat cooler than the recent days — but high humidity will keep the "feels like" temperature uncomfortable, particularly during any lulls between rain bands. Residents who are outdoors for extended periods should stay hydrated.
Sunrise over Metro Manila today is at 5:39 AM and sunset at 6:25 PM. The moon rises at 8:16 PM and sets at 7:38 AM, with lunar illumination at 92 percent — nearly a full moon.
Tidal Information for Manila Bay
For mariners and coastal communities around Manila Bay, PAGASA and NAMRIA's tidal predictions for today, August 1, indicate: a high tide of 0.49 meters at 1:24 AM, a low of 0.47 meters at 3:00 AM, a high of 1.29 meters at 11:27 AM, and a low of 0.17 meters at 7:29 PM. Coastal flooding risk is generally low from tides alone, but storm surge from intense localized thunderstorms or LPA-related surge could compound conditions in vulnerable bayside communities.
Bottom Line
If you are in the Bicol Region, Eastern Visayas, Central Visayas, the province of Quezon, or Marinduque, treat today as a high-alert day for flash floods and landslides. Do not wait for floodwaters to reach your door — know your evacuation route, monitor your local government's advisories, and avoid rivers, storm drains, and flooded roads. The rest of the country should prepare for afternoon thunderstorms and keep an umbrella handy, but the eastern corridor faces the most serious conditions today as the LPA continues to influence weather from the Pacific.
