MANILA, Philippines – Cooler weather brought about by the northeast monsoon or amihan will soon prevail in the country, the Philippine Atmospheric, Geophysical and Astronomical Services (PAGASA) said Monday.   

PAGASA said that based on recent observations and analyses, the general wind pattern has shifted from southwesterly to easterly.

“This signifies that the southwest monsoon season has officially ended,” PAGASA administrator Vicente Malano said in a statement.

He said the strengthening of high-pressure systems over the Asian continent has led to the weakening of southwest monsoon or habagat and the gradual changing of the season.

“With these developments, the climate of the Philippines is on (the) transition to the northeast monsoon Amihan season in the coming days,” Malano said.

PAGASA explained that during the transition, localized thunderstorms may still be experienced in the whole country in the afternoon and evening.

The state weather bureau is also monitoring Typhoon Hagibis, which is still outside the Philippine area of responsibility.

As of 4 p.m. weather bulletin, it was last spotted 2,630 kilometers east of Southern Luzon, packing maximum sustained winds of 175 kilometers per hour (kph) near the center and gustiness of up to 215 kph.

It may enter PAR by Friday if it continues to move in a west-northwest direction at a speed of 25 kph.

MANILA, Philippines — Tropical Storm Goni has rapidly intensified into a severe tropical storm (STS) while moving westward at 10 km/h, the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) said Thursday.

The center of STS Goni was estimated at 1,545 kilometers East of Central Luzon outside the Philippine Area of Responsibility (PAR) 16.6°North ,136.6°East, based on all available data.

The state weather bureau said STS Goni packed a maximum sustained winds of 95 km/h near the center and gustiness of up to 115 km/h.

Once it enters the PAR, Goni will be renamed Rolly, PAGASA said.

It added that STS Goni was forecast to intensify into a typhoon within 24 hours and will continue to intensify while moving over the Philippine Sea.

State meteorologists said Goni may bring heavy rains over the eastern sections of Central and Southern Luzon either by Friday or the weekend as it moves closer.

Tropical Cyclone Wind Signal (TCWS) No. 1 may be raised over some provinces in the Bicol Region and in Northern Samar by Friday evening. —/mbmf

MANILA, Philippines — Water level in Angat Dam further increased following days of rainfall from the onset of tropical cyclones.

As of 6:00 a.m. Thursday (October 29), Angat Dam’s water level is at 200.15 meters, a 0.5 meter increase from 199.65 meters yesterday.

According to state weather bureau PAGASA’s record, Angat’s water level has improved by about 20 meters this month of October brought about by a series thunderstorms and tropical cyclones that entered the country.

To date, Angat Dam needs only about 10 meters of rain to reach its maximum capacity.

Angat Dam is the main water source for domestic requirement in Metro Manila and nearby provinces.

Meanwhile, the National Water Resources Board (NWRB) said water allocation to the Metropolitan Waterworks and Sewerage System (MWSS) will be increased from 44cms to 46cms but allocation for irrigation will be reduced from 30cms to 15cms.

Based on PAGASA’s projection, Angat’s water level may reach up to 212 meters by the end of December.

“Yes. For November ibinalik muna sa 46 cms ang MWSS and reduced ang NIA (National Irrigation Administration) from 30 to 15 cms at harvesting na sila,” said NWRB director Sevillo David Jr.

“Based on rainfall projections of PAGASA and prevailing La Niña period, aabutin ang normal high water level na 212 meters by end of December. We are closely monitoring developments,” he added. MNP (with reports from Rey Pelayo)
