PAGASA: Rain expected over north Luzon, Mindanao


Rain is expected over parts of northern Luzon and Mindanao Monday due to the inter-tropical convergence zone and a tail-end of a cold front, the Philippine Atmospheric Geophysical and Astronomical Services Administration said.

PAGASA, in its 5 a.m. bulletin, said the ITCZ is affecting Mindanao while the tail-end of a cold front is affecting northern Luzon.

According to PAGASA, the tail-end of a cold front is the front boundary of two air masses (cold and warm), found in mid-latitudes, bringing rainfall and cloudiness over affected areas.

The ITCZ, on the other hand, is the result of the converging of trade winds from the northern and southern hemispheres. It brings widespread cloudiness, thunderstorms, precipitation, and moderate to strong surface winds, said PAGASA.

"Northern Luzon and Mindanao will experience mostly cloudy skies with scattered rain showers and thunderstorms. The rest of the country will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms mostly in the afternoon or evening," it said.

But PAGASA forecaster Elvie Enriquez also noted the possibility of more potential cyclones entering Philippine territory.

Enriquez said these looming potential cyclones—low-pressure areas—are embedded in the ITCZ.

"Naka-embed ito sa ating ITCZ. Ang ITCZ ay series ng potential na bagyo," she said in an interview on dzBB radio.

On the other hand, Enriquez said Metro Manila may still experience hot weather like Sunday.

She said the expected high temperature for Monday is 35 degrees Celsius. Sunday's hottest temperature was recorded at 35.6 degrees Celsius, Enriquez added.

Meanwhile, PAGASA said light to moderate winds blowing from the southwest will prevail throughout the archipelago, making coastal waters slight to moderate.
