Amihan brings colder mornings, light rains

The State weather bureau has recorded the coldest morning yet in Metro Manila this "amihan" season with the mercury dropping to 21.8 degrees Celsius on Wednesday morning.

The lowest temperature reading in Metro Manila was observed at around 6:25 a.m. at the Philippine Atmospheric, Geophysical and Astronomical Services Administration's Science Garden monitoring station in Quezon City.

The cold weather is attributed to the strong northeast monsoon or amihan affecting Luzon.

The coldest day in history in Metro Manila was registered twice on February 4, 1987 and December 30, 1988 at 15.1 degrees Celsius.

According to PAGASA, the amihan will bring cloudy skies with light rains over Batanes, Cagayan, Isabela, Quirino, Nueva Vizcaya, Abra, Apayao, Benguet, Ifugao, Kalinga, and Mountain Province.

Partly cloudy to cloudy skies with isolated light amihan rains may also affect Metro Manila and the rest of Luzon.

Meanwhile, the intertropical convergence zone (ITCZ), or the region where the trade winds from the northern and southern hemispheres converge, may bring cloudy skies with scattered rain showers and thunderstorms.

PAGASA warned residents in Mindanao to take necessary precautions in case moderate to heavy rains occur, which may trigger flash floods over low-lying areas or landslides in mountainous communities. 

Visayas will have generally fair weather as it will be partly cloudy to cloudy with only isolated rain showers caused by localized thunderstorms.

However, PAGASA advised that flash floods or landslides may also occur during a severe thunderstorm activity.

PAGASA said a gale warning remains in effect on Wednesday due to strong to gale force winds associated with the surge of amihan.

Rough to very rough seas may affect the northern, eastern, and western seaboards of Northern Luzon.

As sea travel over these waters is still risky, fishing boats and other small sea vessels were advised to prevent from travelling out to sea, while larger sea vessels were asked to remain alert against big waves.
