Typhoon Domeng (Jangmi) has slightly weakened while moving north over the Philippine Sea, but rain remains the bigger threat, according to PAGASA’s 11 a.m. bulletin (June 1). No wind signal is up, but Domeng is still boosting the southwest monsoon (habagat)—which can mean hours of steady rain, sudden downpours, and possible flooding in low-lying areas.
As of the update, Domeng was located 710 km northeast of Itbayat, Batanes, packing 120 kph maximum sustained winds and gusts up to 150 kph, moving north at 20 kph. PAGASA said the system may exit the Philippine Area of Responsibility Monday night and could weaken into a severe tropical storm within 12 hours as it heads toward southern Japan.
Rainfall areas flagged for Monday (June 1) include Batanes, Babuyan Islands, Metro Manila, Calabarzon, Mimaropa, Bicol Region, Panay Island, and Negros Occidental. For Tuesday (June 2), rain may continue over Batanes, Babuyan Islands, Central Luzon, Metro Manila, Calabarzon, Mimaropa, Camarines Norte, Camarines Sur, Aklan, and Capiz. By Wednesday (June 3), wet conditions may persist across Ilocos Region, Benguet, Isabela, Quirino, Nueva Vizcaya, Central Luzon, Metro Manila, Calabarzon, Mimaropa, Camarines Norte, Camarines Sur, Aklan, and Capiz.
Sea conditions also remain risky. PAGASA warned of waves reaching up to 5 meters along the northern and eastern seaboards of Batanes, and up to 2.5 meters in parts of Isabela, Cagayan, Aurora, Camarines Norte/Sur, Kalayaan Islands, and parts of Palawan. Small boats are advised not to sail, and residents in coastal and upland areas should stay alert for strong monsoon winds and rough seas.
