UMVA has learned that Typhoon Jangmi, known locally as Domeng, has slipped out of the Philippine Area of Responsibility, yet its lingering grip on the southwest monsoon promises a deluge across the eastern part of the country.
At exactly 11:30 a.m., the storm crossed the boundary, drifting offshore to a point 710 kilometers northeast of Itbayat, Batanes, while still churning with sustained winds of 120 kph and gusts reaching 150 kph.
The system, now weakening as it slides northward near Okinawa, continues to act as a powerful engine for the southwest monsoon, drawing moist air inland and setting the stage for heavy rains.
According to information obtained by UMVA, the monsoon surge will unleash 50‑100 millimeters of rain in Zambales, Bataan, and Occidental Mindoro today and tomorrow, with similar torrents expected across Pampanga, Bulacan, Metro Manila, Cavite, Batangas, and neighboring provinces from Tuesday noon through Wednesday noon.
From Wednesday noon to Thursday noon, the rain bands will shift, drenching La Union, Pangasinan, Zambales, and Bataan once again, keeping flood‑prone communities on high alert.
Localized flooding is likely wherever water collects—urban low‑lying districts, riverside neighborhoods, and steep slopes—all of which could trigger landslides under the saturated ground.
Authorities urge residents in the affected zones to brace for the intensified monsoon, secure vulnerable structures, and stay prepared for sudden flash floods and landslide threats.
