Up to 12 tropical cyclones possible till October

MANILA — Between seven and 12 tropical cyclones (TCs) may either enter or develop in the Philippine Area of Responsibility during the May-October 2016 period.

State-run Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) made such forecast, noting TCs are among weather systems that may affect the country then.

PAGASA expects zero to one TC for each of May and June this year.

Between one to three TCs are possible this July, PAGASA also said.

For each of August, September and October 2016, PAGASA forecast two to four TCs in the country.

PAGASA likewise forecast transition to the rain-driving southwest monsoon or ‘habagat’ this month.

“Onset of the rainy season associated with the southwest monsoon is expected between late May to mid-June,” PAGASA said in its latest outlook.

Earlier, PAGASA forecast normal onset of the rainy season this year despite the prevailing El Nino phenomenon.

El Nino already entered its decaying stage, PAGASA noted.

Other weather systems that may affect the country during the May-July 2016 period are the easterly wave, local thunderstorms, inter-tropical convergence zone (ITCZ), low-pressure areas (LPAs) and ridge of high-pressure areas, PAGASA said.

Weather systems possibly affecting the country from August to October this year are ‘habagat,’ local thunderstorms, ITCZ, LPAs, ridge of high-pressure area and TCs, PAGASA continued.

A transition from ‘habagat’ to the northeast monsoon or ‘amihan’ is likely by October, added PAGASA. Catherine Teves/PNA/northboundasia.com
