SEVERAL areas in Luzon have been placed under Tropical Cyclone Warning Signal (TCWS) 1 due to Tropical Cyclone Jenny (Koinu), said the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa).
As of 11 a.m. Monday, October 2, 2023, Jenny further intensified as it accelerated toward the northwestward over the Philippine Sea.
It was last spotted at 600 kilometers east of Calayan, Cagayan with maximum sustained winds of 140 kilometers per hour (km/h) near the center, gusts of up to 170 km/h, and central pressure of 965 hPa. It was moving at 15 km/h.
The weather bureau hoisted TCWS 1 over Batanes, Cagayan, including Babuyan Islands, northern and eastern portion of Isabela (Maconacon, Divilacan, Palanan, Santa Maria, San Pablo, Tumauini, Cabagan, Ilagan City, San Mariano, Santo Tomas), Apayao and the northern portion of Ilocos Norte (Carasi, Vintar, Burgos, Dumalneg, Bangui, Pagudpud, Adams).
Pagasa said Jenny will continue to enhance the Southwest Monsoon locally known as habagat, which may bring occasional to monsoon rains over the western portions of Central Luzon, Southern Luzon, Visayas, and Mindanao in the next three days particularly Mimaropa, Western Visayas, Bicol region, Metro Manila, Calabarzon, Bataan, southern portion of Aurora, the northern portion of Palawan including Calamian Islands, Romblon and Occidental Mindoro.
Pagasa advised mariners of motor bancas and similarly-sized vessels to take precautionary measures while venturing out to sea and, if possible, avoid navigating in these conditions, especially if inexperienced or operating ill-equipped vessels.
Jenny is expected to be outside the Philippine area of responsibility between Thursday evening and early Friday morning.
“Jenny is forecast to steadily intensify throughout the forecast period and may reach its peak intensity tomorrow. A slightly weakening trend may begin by mid-Wednesday due to a potential for dry air entrainment and increased wind shear prior to landfall over Taiwan,” said Pagasa. (SunStar Philippines)
