LPA east of extreme Northern Luzon developed into Tropical Depression “Ineng”

Tropical Depression “Ineng” has developed east of extreme northern Luzon. While it is not directly impacting the Philippines, it is slightly enhancing the Southwest Monsoon, which is also influenced by Tropical Storm Haikui. This situation will bring certain weather hazards to parts of the country.

• Location of Eye/Center: 925 km East of Extreme Northern Luzon (21.3 °N, 130.8 °E )
• Movement: Moving Northward slowly
• Strength: Maximum sustained winds of 45 km/h near the center and gustiness of up to 55 km/h

Heavy Rainfall

Tropical Depression Ineng, along with Tropical Storm Haikui, is enhancing the Southwest Monsoon. This will result in occasional to monsoon rains over the western portions of Luzon in the next three days. These rains could lead to localized flooding and should be monitored closely. The Southwest Monsoon is expected to weaken within the week.

Severe Winds:

While Ineng is not directly affecting the Philippines, the enhanced Southwest Monsoon will continue to bring gusty conditions. Areas not under any Wind Signal may experience gusty winds, particularly in coastal and upland/mountainous areas exposed to winds.

Areas Affected:

• Today: Batanes, Ilocos Provinces, the western portion of Pangasinan, Zambales, Bataan, Kalayaan Islands, Lubang Island, Romblon
• Tomorrow: Batanes and Ilocos Provinces

Hazards affecting coastal waters

Ineng itself is less likely to cause rough sea conditions around the Philippines. However, due to the slightly enhanced Southwest Monsoon, a Gale Warning is in effect for several seaboards, particularly in northern and western Luzon, Central Luzon, Southern Luzon, and the western Visayas. Mariners are advised to exercise caution, as hazardous sea conditions may disrupt maritime activities in these areas.

Track and Intensity Outlook

Ineng is expected to remain far from the Philippine landmass, tracking generally northeastward or north-northeastward. It may exit the Philippine Area of Responsibility (PAR) soon, possibly as a tropical storm. Beyond PAR, Ineng will continue its movement towards the waters south of mainland Japan.
