QUEZON CITY, June 19, 2026 — Scattered rainshowers and thunderstorms will sweep across much of the Philippines on Friday, with the state weather agency PAGASA cautioning that severe episodes could trigger flash floods and landslides in vulnerable communities from Luzon to Mindanao.
In its 24-hour public weather forecast issued at 4:00 AM on June 19, 2026, PAGASA said the primary weather driver over much of the country is the easterlies — a prevailing flow of warm, moisture-laden winds originating from the Pacific Ocean — which are currently influencing Central Luzon, Southern Luzon, and the Visayas. Localized thunderstorms account for unsettled weather in the remaining areas.
The forecast is valid from 4:00 AM today, Friday, June 19, until 4:00 AM on Saturday, June 20, 2026.
National Weather Picture
No tropical cyclone is affecting the Philippine Area of Responsibility (PAR) as of this bulletin. Despite the absence of a storm system, the combination of easterlies and localized convective activity is sufficient to generate widespread cloud buildup, intermittent rain, and isolated thunderstorms across virtually all regions of the archipelago.
Residents and travelers across the country should plan for on-and-off showers throughout the day, with the possibility of sudden, intense thunderstorms that may temporarily disrupt outdoor activities and transportation.
Luzon Forecast
Metro Manila
The National Capital Region can expect partly cloudy to cloudy skies with isolated rainshowers or thunderstorms for most of the day. Residents should keep an umbrella on hand and exercise caution during heavy downpours, particularly in low-lying areas of the metro that are historically prone to flooding.
Winds over Luzon will blow from the east to southeast at light to moderate intensity. Yesterday's temperature data recorded at PAGASA's Science Garden station in Diliman, Quezon City showed a maximum of 34.2°C at 11:00 AM and a minimum of 25.2°C at 6:00 AM, with relative humidity ranging from 46% to 89% — reflecting the warm, humid conditions typical of the June easterly season.
Central Luzon and CALABARZON
Both Central Luzon — which includes the provinces of Bulacan, Pampanga, Tarlac, Nueva Ecija, Bataan, and Zambales — and CALABARZON (Cavite, Laguna, Batangas, Rizal, and Quezon) fall under the same forecast: partly cloudy to cloudy skies with isolated rainshowers or thunderstorms driven by the easterlies. Communities situated near riverbanks or at the foot of hills and mountains in these regions should be particularly alert to the possibility of flash floods and landslides should thunderstorms intensify.
MIMAROPA
The island provinces of MIMAROPA — Mindoro, Marinduque, Romblon, and Palawan — are likewise under the influence of the easterlies and will experience partly cloudy to cloudy skies with isolated rainshowers or thunderstorms. Coastal communities and those in interior mountainous areas of Palawan and Mindoro should remain watchful during any prolonged or heavy rainfall events.
Bicol Region
The Bicol Region, encompassing Camarines Norte, Camarines Sur, Albay, Sorsogon, Masbate, and Catanduanes, is included in the easterly-influenced forecast zone and can expect partly cloudy to cloudy skies with isolated rainshowers or thunderstorms. Given the region's geography — including active volcanic slopes and river systems — residents in low-lying and hillside communities are urged to monitor weather updates closely throughout the day.
Northern Luzon
Areas not specifically enumerated by PAGASA — including the Ilocos Region, Cagayan Valley, Cordillera Administrative Region (CAR), and Aurora — fall under the general nationwide forecast of partly cloudy to cloudy skies with isolated rainshowers or thunderstorms caused by localized thunderstorm activity. Mountain provinces in the Cordillera are reminded that steep terrain amplifies the risk of landslides even from moderate rainfall.
Visayas Forecast
The entire Visayas group of islands — covering the Western, Central, and Eastern Visayas regions — will experience partly cloudy to cloudy skies with isolated rainshowers or thunderstorms under the easterlies.
Winds over the Visayas will blow from the east to northeast at light to moderate intensity. Coastal waters in the Visayas will have wave heights of 0.6 to 1.2 meters, categorized as slight to moderate. While these conditions are generally manageable, small bancas and outrigger vessels are advised to stay close to shore and exercise caution, particularly during thunderstorm episodes when seas can become choppy with little warning.
Flash floods and landslides remain a hazard during severe thunderstorms across Visayan provinces, especially in hilly and mountainous interior communities of Leyte, Samar, Negros, Cebu, and Panay.
Mindanao Forecast
Mindanao and its surrounding island groups will see partly cloudy to cloudy skies with isolated rainshowers or thunderstorms, attributed to localized thunderstorm activity rather than the easterlies system influencing the northern and central portions of the archipelago.
Winds over Mindanao will shift from the northeast to northwest at light to moderate strength — a slightly different wind profile from the rest of the country. Coastal waters around Mindanao, including the Sulu Sea and surrounding straits, will also register wave heights of 0.6 to 1.2 meters.
Flash floods and landslides are possible in Mindanao's mountainous interior and river basin communities, including areas in Davao Region, the Caraga Region, BARMM, and Northern and Southern Mindanao, particularly during severe or prolonged thunderstorm episodes.
Wind and Coastal Water Conditions
Across all three major island groups, winds are classified as light to moderate — posing no widespread threat to navigation under normal circumstances. However, PAGASA notes that severe thunderstorms can quickly generate strong, gusty winds and elevated local wave heights that could endanger small watercraft.
Wave heights of 0.6 to 1.2 meters (slight to moderate) are forecast for coastal waters nationwide. Fishermen and maritime workers should remain cautious and monitor local weather bulletins before heading out to sea.
Tidal Information for Manila Bay
According to tidal predictions provided courtesy of the National Mapping and Resource Information Authority (NAMRIA), Manila Bay will experience a high tide of 1.42 meters at 12:44 PM and a low tide of -0.09 meters at 9:24 PM today, June 19. Coastal barangays along Manila Bay should be mindful of these tidal peaks, especially in combination with any heavy local rainfall.
Astronomical Data for Metro Manila
The sun will rise over Metro Manila at 5:28 AM and set at 6:27 PM today. The moon will rise at 9:32 AM and set at 10:25 PM, with lunar illumination at 25% — a waxing crescent phase that will provide minimal nighttime light.
Safety Advice
PAGASA specifically flags the risk of flash floods and landslides during severe thunderstorm events across all regions. Residents in the following situations should exercise heightened caution:
- Those living in low-lying areas near rivers, creeks, and esteros
- Communities on slopes, hillsides, or near mountain foothills
- Motorists crossing low-water bridges or flood-prone roads
- Fisherfolk and maritime workers operating small vessels in open water
- Outdoor workers and construction crews exposed to lightning risk during thunderstorms
In the event of a severe thunderstorm, PAGASA advises the public to seek sturdy shelter immediately, avoid trees and metal structures, and refrain from wading through floodwaters of unknown depth.
"When thunder roars, go indoors." Even isolated thunderstorms can produce localized but intense rainfall over a short period, rapidly raising water levels in drainage systems and small waterways.
Local government units (LGUs) and disaster risk reduction offices are encouraged to pre-position response teams and ensure early warning systems are activated in communities with known flood and landslide exposure.
