MANILA – The northeast monsoon, locally known as “amihan,” will affect parts of Luzon on Sunday (19 Jan 2025), bringing cloudy skies and rainfall, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

In its 24-hour forecast, PAGASA reported that the provinces of Cagayan Valley, Aurora, and Quezon will experience cloudy skies with moderate to heavy rains due to the amihan. The weather bureau has cautioned that these conditions could lead to flash floods and landslides, particularly in low-lying and mountainous areas.

In Metro Manila and the rest of Luzon, partly cloudy to cloudy skies will prevail, with isolated light rains also attributed to the northeast monsoon. However, PAGASA indicated that these areas are not expected to face any significant weather impacts.

Elsewhere in the country, including the Visayas and Mindanao, conditions will be partly cloudy to cloudy with isolated rain showers or thunderstorms, driven by the easterlies. These localized weather events may also trigger flash floods or landslides, particularly during intense thunderstorms.

Wind conditions will range from moderate to strong in Northern Luzon and the eastern parts of Central and Southern Luzon, with winds coming from the east to northeast. Coastal waters in these regions are expected to be moderate to rough, with wave heights reaching 2.1 to 3.4 meters, posing a risk to small seacrafts.

In the rest of the country, light to moderate winds are expected, with coastal waters remaining slight to moderate, providing safer conditions for maritime activities.
