Manila: Severe Tropical Storm (STS) Tino, internationally known as Kalmaegi, has further intensified while moving west southwest over the Philippine Sea, as announced by the Philippine Atmospheric, Geophysical and Astronomical Services Administration on Monday. According to Philippines News Agency, the weather bureau's 5 a.m. bulletin reported that the center of Tino, as of 4 a.m., was positioned 430 kilometers east of Guiuan, Eastern Samar. It is traveling west southwest at a speed of 30 kilometers per hour, with maximum sustained winds reaching 110 kilometers per hour near the center and gusts up to 135 kilometers per hour. Tropical Cyclone Wind Signal (TCWS) No. 2 has been raised over several areas including the central and southern parts of Eastern Samar, Samar, Leyte, Biliran, Southern Leyte, Camotes Islands, and the eastern portion of Bohol. Additionally, Dinagat Islands, Surigao del Norte, and parts of Agusan del Norte and Surigao del Sur are also under TCWS No. 2. TCWS No. 1 is in effect in parts of Luzon such as Sorsogon, Masbate, and portions of Albay, Romblon, Oriental Mindoro, and Occidental Mindoro, as well as in Visayas regions including Northern Samar, Cebu, and several more. Certain areas in Surigao del Sur, Agusan del Sur, Agusan del Norte, Misamis Oriental, and Camiguin are also under TCWS No. 1. PAGASA weather specialist Daniel James Villamil indicated that the highest wind signal anticipated during Tino's passage could reach TCWS No. 4. He warned that widespread severe flooding and landslides are expected due to significant heavy rains, especially in areas under TCWS No. 1. Tino is forecast to make its initial landfall over Eastern Samar, Leyte, or Dinagat Islands by midnight or early Tuesday morning. Villamil also stated that Tino is expected to continuously intensify, potentially reaching the typhoon category within the next 12 hours and maintaining this strength throughout its passage over the country. Rapid intensification is possible within the next 24 hours, and there is a chance i t could develop into a super typhoon based on alternate scenarios and climatological data. Residents near coastal areas, particularly in Caraga, are advised to evacuate to higher ground due to the threat of storm surge. Meanwhile, the northeast monsoon (amihan) is expected to bring strong to gale-force gusts, particularly in coastal and upland areas of several regions including Cagayan Valley, Ilocos Norte, and Metro Manila.
