Most areas in the country would have fair weather for the All Saints’ Day and All Souls’ Day even if different weather systems prevail, the country’s weather bureau said.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration’s (Pagasa) Friday afternoon weather update showed that the intertropical convergence zone (ITCZ) still affects southern provinces, while the northeast monsoon or amihan, along with the shear line, brings cloudy weather to the northern provinces.
However, rain would only be isolated and may happen only in the afternoon or at night.
‘As of now, even if we have several weather systems affecting the country, we can expect that we will have generally fair weather conditions for this All Souls’ Day weekend, which means there may be partly cloudy skies over many areas and the sun will shine from time to time,’ Pagasa weather specialist Benison Estareja said in Filipino.
‘But by afternoon and night, there is still a chance for isolated rain showers, thunderstorms, and lightning strikes,’ he added.
Pagasa is still monitoring the ITCZ, but no heavy rain showers are expected on the areas affected by the convergence of winds from the northern and southern hemispheres.
‘As of now, for Southern Luzon, Visayas, and Mindanao, the intertropical convergence zone or the meeting point of winds from the northern and southern hemispheres is still there, but from today and up to the next days, rains due to the ITCZ will not be intense,’ Estareja said.
‘The northeast monsoon or amihan meanwhile, only affects the extreme northern Luzon area; it does not affect other areas south, and it will only bring rains over Batanes. The shear line is also not that active, only bringing scattered rain showers and thunderstorms somewhere in Cagayan, Isabela, and Aurora,’ he added.
Two low-pressure areas (LPA) were monitored along the ITCZ – one located 1,595 kilometers east of Northeastern Mindanao, and the second at 160 kilometers west-southwest of Coron, Palawan. The LPA west of Palawan is not expected to develop into a tropical cyclone, but the other LPA east of Mindanao has a medium chance of progressing as a tropical depression.
Pagasa said that the LPA east of Mindanao may enter the Philippine area of responsibility (PAR) by Sunday night or Monday morning, and may be the 20th tropical cyclone inside the PAR for the calendar year. It is forecast to cross the Visayas and Southern Luzon area, but Pagasa clarified that it may still deviate from the current predicted track.
Another LPA is expected to form between November 6 and November 12, also originating from the Pacific Ocean.
Due to the cloudy weather, temperatures over Luzon are expected to be at a normal level, ranging from 25 to 29 degrees Celsius in Tuguegarao; 25 to 34 degrees in Laoag; 17 to 25 degrees in Baguio City; 25 to 32 degrees in Metro Manila; 23 to 29 degrees over Tagaytay; 25 to 31 degrees in Legazpi, and 25 to 30 degrees in Puerto Princesa.
Cloudy weather is also seen to persist over Visayas and Mindanao, leading to temperatures of 25 to 31 degrees Celsius in Iloilo and Tacloban; 24 to 32 degrees in Zamboanga and Cebu; and 24 to 31 degrees in Cagayan de Oro and Davao.
No gale warning has been raised, but Pagasa said that sea conditions over the extreme northern Luzon seaboard will be moderate to rough, with possible wave height of 1.5 meters to 2.8 meters
