MANILA, Philippines – The northern, northeastern and northwestern parts of Luzon may continue to experience rains over the next few days, as Typhoon “Mina” lingers in the country, according to weather bureau PAGASA.

Laoag, Ilocos Sur, all the way to Aparri and Cagayan will be extremely wet in the next two days, said PAGASA officer-in-charge and Department of Science and Technology Undersecretary Graciano Yumul on ANC's "The Rundown" on Friday.

Yumul said Mina, which has remained almost stationary in Luzon, is expected to leave the Philippine Area of Responsibility (PAR) on Tuesday but may linger until Friday, as Tropical Storm "Talas" (international name) persists in the Pacific Ocean.

"There's a binary interaction, that's why you have a very slow moving typhoon, that's almost stationary. Mina is supposed to hit Taiwan but it won't. It's supposed to go out on Tuesday but there are new models that say it's going to go out Friday, before hitting Taiwan, [Mina] will make a U-turn before going out of the PAR.

When Talas heads for Japan, Mina will go eastward and go out of PAR," explained Yumul.

Lingering tropical cyclone

If Mina stays until Friday, it will become the longest staying tropical cyclone in the country this year after Typhoon Kabayan, which lingered in the PAR for almost 10 days.

"If it stays up to Friday, you're looking at a 14-day typhoon and normally it should only stay for two to four days."

Yumul said climate change may be the reason for the longer duration and greater intensity and frequency of tropical cyclones.

"These are products of global warming, changes in the climate and these are the things you're supposed to be expecting."

Rainfall intensity alert

Meantime, Yumul said the weather bureau is developing a new system to warn of rainfall volume, designed after the Hong Kong model.

"In response to the needs of the country, what PAGASA is doing right now is we're coming out with a rainfall intensity alert. We're actually practicing it in Metro Manila. The National Capital Region is under a Doppler radar so we can do a now-casting, where it falls, how much rain will fall and where it will fall. If we're able to do it well, we can apply it to the whole country."

"By the end of the year, we hope we can have the alert system. It will be a color-coded alert: yellow for light, red medium grade, and black you better stay where you are because it can cause a lot of flooding," said Yumul.
