Tropical Storm Enteng has slightly intensified after slowing down over the coastal waters of Vinzons, Camarines Norte Monday and may turn into a severe tropical storm before exiting the Philippines by Wednesday, weather bureau PAGASA said.

As of 4 a.m., the center of Tropical Storm Enteng was estimated based on all available data over the coastal waters of Vinzons, Camarines Norte.

Packing 75 kph winds and gusts of up to 90 kph, the storm is moving west northwestward at 10 kph and may make landfall over Isabela or Cagayan by Monday afternoon or evening. 

It added Enteng may also make landfalls over Aurora and Babuyan Islands.

“Shall the forecast track shift further to the west, landfall over the northern portion of Aurora is not ruled out,” PAGASA said.

“From tomorrow early morning (3 September), Enteng will generally turn west northwestward. Possible landfall over Babuyan Islands is also not ruled out.

Malacanang Palace has suspended class at all levels in Metro Manila due to the inclement weather brought about by Enteng. 

The weather bureau said Enteng may slow down even further Tuesday to Wednesday even as it gathers strength over Luzon Strait. “Enteng will continue to move west northwestward while accelerating and is expected to exit the Philippine Area of Responsibility by Wednesday evening to Thursday early morning (5 September),” it said.

It said Enteng is forecast to maintain tropical storm category until Tuesday and will intensify into a severe tropical storm by Wednesday. It may also reach a peak category of typhoon by Thursday or Friday. “Further intensification over the Philippine Sea is still likely due to favorable conditions,” it said.

PAGASA said Camarines Norte, Camarines Sur, Albay, Polillo Island, and the southern portion of mainland Quezon are set to experience 200mm of accumulated rainfall Monday, while Aurora, the rest of Quezon, Catanduanes, Masbate, and Sorsogon will experience 100-200mm of accumulated rainfall.

Metro Manila, Isabela, Quirico, Bulacan, the rest of CALABARZON, Marinduque, and Romblon will experience 50-100mm of accumulated rainfall today.
