Excerpt: A low-pressure area west of La Union developed into Tropical Depression Maymay late Tuesday, August 4, 2026. Benguet and the rest of the Cordillera are under Tropical Cyclone Wind Signal No. 1, while the system may strengthen into a tropical storm before making landfall over Ilocos Sur or La Union.

Tropical Depression Maymay Forms West of La Union; Benguet Under Signal No. 1

The low-pressure area west of La Union developed into Tropical Depression Maymay late Tuesday, August 4, 2026, according to the tropical cyclone advisory issued by PAGASA at 11:00 PM.

The center of Maymay was estimated at 130 kilometers west northwest of Bacnotan, La Union.

The tropical depression had maximum sustained winds of 55 kilometers per hour near the center and gustiness of up to 70 kilometers per hour.

PAGASA listed Maymay as moving east northeastward at 10 kilometers per hour. Its track outlook, however, indicated that the system may remain nearly stationary during the next 12 hours before moving eastward toward Northern Luzon.

Maymay may make landfall over Ilocos Sur or La Union on Wednesday afternoon or evening, August 5.

What This Means for Baguio City and Benguet

The province of Benguet is under Tropical Cyclone Wind Signal No. 1.

Signal No. 1 means winds ranging from 39 to 61 kilometers per hour may be experienced within approximately 36 hours. Intermittent rain may also occur during this period.

PAGASA said minimal to minor impacts from strong winds are possible in areas under Signal No. 1.

Baguio City was not separately named in the list of areas under the wind signal in the supplied advisory. However, the city may still experience rain and strong wind gusts because of its location within the Benguet highlands and the expected effects of Maymay and the Southwest Monsoon over most of Luzon.

Winds may be stronger in exposed upland and mountainous areas. Residents should take extra precautions along ridges, open roads, elevated communities, construction sites, and locations near trees, signs, temporary structures, or unsecured roofing materials.

Maymay’s projected path across Northern and Central Luzon also means weather conditions may change quickly during Wednesday and Thursday.

Entire Cordillera Under Signal No. 1

All six provinces of the Cordillera Administrative Region are under Tropical Cyclone Wind Signal No. 1:

  • Abra
  • Apayao
  • Benguet
  • Ifugao
  • Kalinga
  • Mountain Province

Residents throughout the Cordillera should prepare for intermittent rain and strong winds, particularly in exposed mountainous locations.

Rain may also increase the risk of landslides, falling rocks, soil erosion, and road obstructions along mountain roads and communities near steep slopes.

What Signal No. 1 Means

Tropical Cyclone Wind Signal No. 1 indicates that a tropical cyclone may affect the locality.

Winds of 39 to 61 kilometers per hour may be experienced within approximately 36 hours. Intermittent rain may also occur.

Possible effects include:

  • Very light or no damage to low-risk structures
  • Light damage to more vulnerable structures
  • Slight damage to houses made of light materials in exposed communities
  • Broken twigs and small tree branches
  • Tilted or damaged banana plants
  • Possible damage to rice crops during the flowering stage
  • Gradually increasing waves along affected coastal waters

PAGASA said the wind signal may be upgraded if Maymay strengthens and moves closer to land.

The highest wind signal that may be raised during Maymay’s passage is Signal No. 2.

Maymay May Become a Tropical Storm

PAGASA said Maymay may intensify while approaching the landmass of Northern Luzon.

The system could reach tropical storm category during the next 12 hours.

After making landfall, Maymay is expected to weaken while crossing the mountainous terrain of Northern and Central Luzon.

It may weaken into a tropical depression by Thursday morning, August 6, and could be downgraded further into a low-pressure area by Thursday afternoon or evening.

Possible Landfall Over Ilocos Sur or La Union

Maymay is forecast to remain nearly stationary during the next 12 hours before beginning to move eastward.

Based on PAGASA’s track outlook, the center of the tropical cyclone may make landfall over Ilocos Sur or La Union on Wednesday afternoon or evening.

After landfall, Maymay is expected to cross portions of Northern and Central Luzon until Thursday.

PAGASA emphasized that the track may still shift within the forecast confidence cone.

Heavy rainfall and severe winds may also affect places outside the projected landfall area and forecast path.

Forecast Positions of Maymay

Date and TimeForecast Location
August 5, 8:00 AM115 km west northwest of Bacnotan, La Union
August 5, 8:00 PMOver the coastal waters of Candon City, Ilocos Sur
August 6, 8:00 AMIn the vicinity of Tubo, Abra
August 6, 8:00 PMIn the vicinity of Tumauini, Isabela

These forecast positions may still change as PAGASA receives additional weather observations.

Heavy Rainfall Remains a Major Concern

PAGASA referred the public to Weather Advisory No. 13 for the detailed heavy rainfall outlook associated with Maymay and the Southwest Monsoon.

The tropical cyclone advisory did not provide specific rainfall amounts for Baguio City, Benguet, or other locations.

Residents should closely monitor rainfall advisories and warnings issued by PAGASA’s regional weather offices.

Communities should remain alert for:

  • Flooding in low-lying and poorly drained areas
  • Rising water levels along rivers and waterways
  • Landslides and falling rocks near steep slopes
  • Soil erosion and ground movement
  • Road slips and blocked mountain roads
  • Reduced visibility during heavy rain

Heavy rainfall may still occur outside the projected landfall area.

Strong Winds May Affect Most of the Country

The Southwest Monsoon and the outer circulation of Maymay may bring strong to gale-force gusts over the following areas:

Tuesday Night and Wednesday, August 5

  • Most of Luzon
  • Most of the Visayas
  • Surigao del Norte
  • Dinagat Islands
  • Misamis Occidental
  • Camiguin
  • Lanao del Norte
  • Sarangani
  • Davao Occidental
  • Davao Oriental

Thursday, August 6

  • Most of the country

Strong gusts may be more noticeable in exposed coastal and upland areas.

Gale Warning Over Western Northern Luzon

A Gale Warning is in effect over the western seaboard of Northern Luzon.

Very rough seas with waves reaching up to 4.5 meters are expected over:

  • Ilocos Sur
  • La Union
  • Pangasinan

Sea travel is considered dangerous for vessels of all types and sizes.

All mariners are advised to remain in port. Vessels already at sea should seek shelter or proceed to a safe harbor as soon as possible.

Rough Seas Expected in Other Areas

Waves reaching up to 3.5 meters are expected over:

  • Seaboard of Zambales
  • Eastern seaboard of Bataan
  • Eastern seaboard of Lubang Island

Waves reaching up to three meters are expected over:

  • Northern seaboard of Batanes
  • Eastern seaboard of Davao Oriental

Small vessels, including motorbancas, should not venture out to sea under these conditions.

Moderate to rough seas with waves reaching two to 2.5 meters are also expected over several coastal areas in Luzon, the Visayas, and Mindanao.

Operators of motorbancas and similarly sized vessels should take precautionary measures and avoid sailing whenever possible.

Public Safety Reminders

Residents are advised to:

  • Monitor official PAGASA advisories and local government announcements.
  • Inspect roofs, windows, walls, and other parts of the house that may need repairs.
  • Clean drainage canals and remove materials that may block the flow of water.
  • Secure signs, plant pots, outdoor furniture, roofing sheets, and other loose objects.
  • Avoid staying or parking near old trees, unstable slopes, retaining walls, billboards, and temporary structures.
  • Prepare flashlights, medicines, food, drinking water, charged mobile phones, and emergency supplies.
  • Avoid unnecessary travel during periods of heavy rain or strong winds.
  • Never cross flooded roads, rivers, drainage channels, or overflowing waterways.
  • Watch for ground cracks, leaning trees, unusual sounds, and other warning signs of landslides.
  • Follow evacuation and safety instructions issued by local authorities.
  • Harvest crops that are ready when conditions remain safe.

Disaster preparedness offices in areas under Signal No. 1 have been placed on alert.

Residents may continue normal activities where conditions remain safe, but they should be prepared for sudden changes in rainfall, wind, and road conditions.

The next tropical cyclone advisory for Maymay will be issued by PAGASA at 5:00 AM on Wednesday, August 5, 2026.
