ONSET OF THE NORTHEAST MONSOON

Over the past several days, the high-pressure area over Siberia has strengthened, leading to a strong surge of northeasterly winds which is expected to affect the northern portion of Luzon beginning today and tomorrow, after the passage of Super Typhoon Pepito. Furthermore, successive surges of northeasterly winds are expected over the next two weeks, leading to an increase in atmospheric pressure and cooling of surface air temperature over the northern portion of Luzon. The development of these meteorological patterns indicates the Onset of the Northeast Monsoon (Amihan) season.

With these developments, the northeasterly wind flow is expected to be more dominant in most of the country, bringing cold and dry air. Episodes of wind and cold temperature surges, as well as increasing prevalence of rough sea conditions, especially over the seaboards of Luzon are also expected in the coming months.

PAGASA will continue to monitor the country's weather and climatic conditions. Meanwhile, the public and all concerned agencies are advised to monitor relevant PAGASA information regularly.
