Excerpt:Tropical Depression Luis remained almost stationary east of Aurora early Monday, August 3, 2026. Parts of Cagayan Valley and eastern Cordillera remain under Signal No. 1. Baguio City and Benguet are not under a wind signal, but strong winds and rain may still affect the area due to Luis and the Southwest Monsoon.

Luis Remains Stationary East of Aurora; Possible Northern Luzon Landfall

Tropical Depression Luis maintained its strength while remaining almost stationary over the Philippine Sea east of Aurora early Monday, August 3, 2026.

According to the tropical cyclone advisory issued by PAGASA at 5:00 AM, the center of Luis was estimated at 130 kilometers east southeast of Casiguran, Aurora.

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

The tropical depression was almost stationary as of the latest observation.

PAGASA said Luis may begin moving northwestward and could make landfall or pass close to Northern Luzon between Monday night and early Tuesday morning, August 4. However, its forecast track remains highly uncertain and may still change.

What This Means for Baguio City and Benguet

Baguio City and Benguet are not under a tropical cyclone wind signal as of the 5:00 AM advisory.

However, PAGASA said the Southwest Monsoon and the outer circulation of Luis may bring strong to gale-force gusts over most of Luzon on Monday and Tuesday.

Because Baguio City and Benguet are mountainous, winds may become stronger in exposed locations, including ridges, open roads, elevated communities, construction areas, and places with trees, signs, temporary structures, or unsecured roofing materials.

Rain may also affect Baguio City and Benguet even though the areas are outside the current wind signal coverage.

PAGASA referred the public to Weather Advisory No. 6 for the detailed heavy rainfall outlook due to Luis and the Southwest Monsoon. The tropical cyclone advisory did not provide specific rainfall amounts for Baguio City or Benguet.

Residents should continue monitoring rainfall advisories and warnings issued by PAGASA’s regional weather office and local disaster risk reduction authorities.

• Broken twigs and small branches
• Tilted or damaged banana plants
• Light damage to vulnerable structures
• Possible damage to rice crops during the flowering stage
• Gradually increasing waves along affected coastal waters

Wind conditions may be stronger in exposed coastal and upland areas. Sheltered locations may experience weaker winds.

Heavy Rainfall Remains a Concern

PAGASA referred the public to Weather Advisory No. 6 for the detailed heavy rainfall outlook associated with Luis and the Southwest Monsoon.

Heavy rain may still affect locations outside the projected track and possible landfall area of the tropical depression.

Communities in low-lying areas, near rivers and drainage channels, and along steep or unstable slopes should remain alert for flooding and landslides.

Residents should monitor local rainfall warnings because weather conditions may vary between neighboring cities and municipalities.

Strong Winds May Affect Most of Luzon and Visayas

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

Monday, August 3, and Tuesday, August 4

• Most of Luzon
• Most of the Visayas
• Lanao del Norte

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

Luis May Approach or Cross Northern Luzon

PAGASA said Luis is expected to move generally northwestward.

Based on the current forecast, the tropical depression may make landfall or pass close to Northern Luzon between Monday night and early Tuesday morning.

After approaching Northern Luzon, Luis is forecast to make a sharp turn toward the east northeast and move away from the Philippine landmass.

PAGASA emphasized that the forecast track remains highly uncertain and may still change in succeeding bulletins.

A change in the storm’s speed or direction could also affect which areas are placed under wind signals.

Forecast Positions of Luis

These forecast positions may still be adjusted as PAGASA receives new observations.

Luis May Weaken by Wednesday

Luis is forecast to remain a tropical depression during most of the forecast period.

PAGASA said the system may weaken into a remnant low by Wednesday, August 5.

The remaining circulation of Luis may later be absorbed into the circulation of Tropical Cyclone Dolphin.

Moderate to Rough Seas Expected

Moderate to rough seas are forecast over several coastal areas during the next 24 hours.

Waves reaching up to 2.5 meters are expected over:

• Eastern seaboard of Isabela
• Eastern seaboard of Davao Oriental
• Northeastern seaboard of Aurora

Waves reaching up to two meters are expected over:

• Seaboards of Batanes
• Northern and eastern seaboards of the Babuyan Islands
• Eastern seaboard of mainland Cagayan

Public Safety Reminders

Residents are advised to:

• Monitor official PAGASA advisories and local government announcements.
