MANILA – More provinces are being affected by Typhoon “Ramil” (international code name Lupit) as it approaches Northern Luzon, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) reported on Tuesday.

In its 11 a.m. tropical cyclone update, PAGASA said Public Storm Signal No. 2 is up over the Batanes Group of Islands, Cagayan, Calayan Island, Babuyan Islands and Isabela.

Signal No. 1 has been raised over Ilocos Norte, Apayao, Abra, Kalinga, Mt. Province, Ifugao, Nueva Vizcaya, Polillo Island, Quirino and Aurora.

Residents in low-lying areas and near mountain slopes under Signals No. 1 and No. 2 have been advised by the weather bureau to take precautionary measures against flashfloods and landslides.

Those living along coastal areas in provinces under Signal No. 2, meantime, were advised to be on alert against big waves.    

Thursday landfall?

“Ramil” was spotted as of 10 a.m. at 820 kilomters east northeast of Aparri, Cagayan, packing winds of up to 195 kph near the center and gusts of up to 230 kph.

It is moving west at 17 kph towards Northern Luzon. It is expected to be at 460 km east northeast of Aparri Wednesday morning, 120 km northeast of Aparri Thursday morning, and 150 km southwest of Laoag City Friday morning.

PAGASA said the typhoon could make landfall Thursday in Cagayan.

Aside from “Ramil,” another weather disturbance is in the Philippine Area of Responsibility.

An Intertropical Convergence Zone (ITCZ) which previously affected Luzon and Visayas on Monday is now affecting Southern Luzon, Visayas and Mindanao.

PAGASA said in its 5 a.m. weather bulletin on Tuesday that the whole country will have mostly cloudy skies with scattered rainshowers and thunderstorms.

Situation of dams

Five out of the seven dams in Central and Northern Luzon continue to have spilling operations as of 9 a.m. Tuesday.

According to PAGASA, the dams are Ambuklao (4 gates opened, water release at 58 cubic meters per second), Binga (1 gate, 132 cms), San Roque (2 gates, 424 cms), Pantabangan (1 gate, 220 cms), and Magat (4 gates, 1824 cms).

The floodgates of Angat and Ipo dams have already closed Monday morning.

Meanwhile, the National Power Corporation (Napocor) has revised its protocol for the release of water from dams. Dam operators should now issue a warning six hours before water is released from the previous four hours prior to release.

The warning should also include the number of gates that will be opened and volume of water that will be released.

This comes weeks after tropical storms “Ondoy” and “Pepeng” devastated Metro Manila, Central and Northern Luzon with massive flooding due in part to the release of water from dams in Luzon. – With a report from ANC’s “Dateline Philippines”
