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.
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.

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.
All six provinces of the Cordillera Administrative Region are under Tropical Cyclone Wind Signal No. 1:
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.
Signal No. 1 is also in effect over:
No areas in the Visayas or Mindanao are under a tropical cyclone wind signal as of the 11:00 PM advisory.
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:
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.
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.
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.
| Date and Time | Forecast Location |
|---|---|
| August 5, 8:00 AM | 115 km west northwest of Bacnotan, La Union |
| August 5, 8:00 PM | Over the coastal waters of Candon City, Ilocos Sur |
| August 6, 8:00 AM | In the vicinity of Tubo, Abra |
| August 6, 8:00 PM | In the vicinity of Tumauini, Isabela |
These forecast positions may still change as PAGASA receives additional weather observations.
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:
Heavy rainfall may still occur outside the projected landfall area.
The Southwest Monsoon and the outer circulation of Maymay may bring strong to gale-force gusts over the following areas:
Strong gusts may be more noticeable in exposed coastal and upland areas.
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:
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.
Waves reaching up to 3.5 meters are expected over:
Waves reaching up to three meters are expected over:
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.
Residents are advised to:
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.
