TROPICAL storm “Auring” continues to weaken and is expected to be downgraded to a low pressure area (LPA) by Monday, but Signal No. 1 remains hoisted over some parts of the Visayas, Mindanao and a Luzon province, the state-run weather agency said on Saturday.
Signal No. 1 was up over the southeastern portion of Masbate (Cataingan, Cawayan, Dimasalang, Esperanza, Palanas, Pio V. Corpuz and Placer) and in the Visayas — over Northern Samar, Eastern Samar, Samar, Biliran, Leyte, Southern Leyte, Cebu, Negros Oriental, Bohol, Siquijor and the northern portion of Negros Occidental (Bacolod City, Bago City, Cadiz City, Calatrava, Enrique B. Magalona, Escalante City, Manapla, Murcia, Sagay City, Salvador Benedicto, San Carlos City, Silay City, Talisay City, Toboso and Victorias City).
In Mindanao, the same storm signal was still up over Dinagat Islands, Surigao del Norte, Surigao del Sur, Agusan del Norte, Agusan del Sur, Davao Oriental, Davao de Oro, Davao del Norte, Davao City, Camiguin, Misamis Oriental and Bukidnon.
Based on its 5 p.m. advisory on Saturday, it is likely to make landfall over the Dinagat-Homonhon-Leyte area Sunday night or early Monday morning then cross the Visayas and Mimaropa (Mindoro, Marinduque, Romblon and Palawan), the Philippine Atmospheric, Geophysical and Astronomical Services (Pagasa) said.
“Auring is more likely to weaken to tropical depression before it makes landfall over Caraga. It will likely further weaken to an LPA by Monday due to significant terrain interaction and persistent vertical wind shear during this passage over the archipelago,” weather specialist Raymond Ordinario told The Manila Times.
At 4 p.m. Saturday, Ordinario said the center of the tropical storm was estimated at 440 kilometers east-southeast of Hinatuan, Surigao del Sur.
He said it was moving northwestward at the speed of 15 kilometers per hour (kph) with maximum sustained winds of 65 kph near the center and gustiness of up to 80 kph.
Until Sunday, Ordinario said Dinagat Islands, Surigao del Norte, Northern Mindanao, Bicol Region, Mimaropa, Quezon, and the rest of the Visayas and Caraga will experience moderate to heavy rains.
By Monday, light to moderate with at times heavy rains is expected to be experienced over Bicol Region, Mimaropa, Western Visayas, Cagayan, Isabela, Aurora and the southern portion of Quezon due to the combined effects of the weather disturbance and the shear line, Pagasa said.
In the next 24 hours, Ordinario said, the combined effects of the surge of the northeast monsoon (amihan) and Auring will bring strong to gale-force winds over the areas where the storm signal is in effect as well as over the rest of the Visayas, Bicol Region, Calabarzon (Cavite, Laguna, Batangas, Rizal and Quezon), Mindoro Provinces, Marinduque, Romblon and the northern portion of Palawan (including Calamian, Cuyo and Kalayaan Islands).
