MANILA, March 30 (PNA) -- Some turbulence in seas bordering the country's eastern seaboard is still likely until Friday morning (March 31) despite weakening of the northeast monsoon or 'amihan' and its strong to gale-force winds that previously fanned rough to very rough waters in Northern Luzon.
Moderate to rough seas and waves up to 2.5 meters high are possible off the eastern seaboard spanning Northern Luzon to Mindanao, noted weather forecaster Benison Estareja from Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
"Exercise caution when sailing there," he reminded the public.
He particularly alerted small seacraft to the expected sea conditions.
The easterlies are affecting the country's eastern section at present and may mainly fan such sea conditions, he noted.
Estareja said a high-pressure area is prevailing in mainland Asia so 'amihan' still exists.
He noted 'amihan' is directly affecting China at present.
"We can't yet say 'amihan' terminated already after weakening," he said.
According to Estareja, 'amihan' may even resurge this Sunday (April 2).
If 'amihan' resurges, he said it's possible for strong togale-force winds associated with this weather system to begin affecting Northern Luzon again.
Such winds may fan there anew rough to very rough seas with waves up to 4.5 meters high, making sailing dangerous.
The annual 'amihan' starts over Siberia as cold, dry air mass which gathers moisture while traveling across Pacific Ocean towards the Philippines.
PAGASA said 'amihan' affects the Philippines' eastern portions from October to March.
'Amihan' is characterized by widespread cloudiness with rains or showers. (PNA)
