North Luzon’s waters still far from calm

MANILA — Moderate to rough seas are still likely off Northern Luzon’s northern and eastern seaboards this Sunday despite the weakening of strong to gale-force winds associated with the northeast monsoon or ‘amihan’, the state weather bureau has said.

Expected winds in the area will not reach gale-force intensity as in the previous days but can still be strong enough to fan moderate to rough seas bordering both seaboards, noted weather forecaster Aldczar Aurelio of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

“Observe caution when venturing to sea,” he reminded people planning to sail in the area.

Aurelio said the weakening of the high-pressure area (HPA) in China has affected the intensity of ‘amihan’ and winds associated with this weather system.

These winds can reach gale-force intensity again if the HPA intensifies anew, he said.

In its 24-hour forecast released Saturday morning, PAGASA said moderate to strong winds from the northeast will prevail over Luzon and the Visayas, resulting in moderate to rough coastal waters.

“Elsewhere, winds will be light to moderate coming from the northeast to northwest with slight to moderate seas,” the bureau noted.

According to PAGASA, the ‘amihan’ starts over Siberia as cold, dry air mass gathers moisture while traveling across the Pacific Ocean.

The ‘amihan’, which affects the Philippines’ eastern portions from October to late March, is characterized by “widespread” cloudiness with rains or showers.

PAGASA has announced the onset of the annual ‘amihan’ in the country after observing strong to gale-force northeasterly winds prevailing over Northern Luzon’s seaboards due to the gradual strengthening of the high-pressure system over Siberia. Catherine Teves/
