At least 58.3 m.l. of rainfall was recorded in Northern Mindanao, as of January 18, this year, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said.
This volume of rainfall already represents 70.40 percent of the expected natural rainfall of 82.8m.l. for the month, Mario Goya, Weather Specialist of PAGASA, region 10, said, during a recent meeting of the Regional Disaster Risk Reduction and Management Council (RDRRMC).
Goya said the highest volume of normal rainfall for the year is expected in the month of July with 244.1 m.l., followed by June with 207.7 m.l., August with 205.2m.l. and Sept. with 204.4m.l.
He said the rest of the year will have the following volume of rainfall: October, 188.1 m.l., November, 138.6m.l., May, 109.8m.l., December, 105.8m.l., February, 65m.l., April, 58.1 m.l. and lowest in March with 44.8 m.l.
Meanwhile, the possibility of the cold episode is expected to last into the Northern Hemisphere Spring, from March, April and May, this year, as the moderate La Niña event continues to persist in the tropical Pacific, the PAGASA said in its La Niña Advisory No. 4 issued recently.
The advisory said there is a low probability of tropical cyclone occurrence in the Philippine Area of Responsibility (PAR), but the weather systems that will likely affect the country this month are still the tail end of the cold front, the North East Monsoon or “Amihan,” the inter-tropical convergence zone (ITCZ) and the ridge of the high power area (HPA).
However, there was no tropical cyclone that entered PAR last December but the northeast monsoon and tail end of the cold front brought significant rainfall that caused flooding and landslides due to continuous moderate to heavy rain in some parts of the country, particularly over the Surigao provinces in Mindanao.
Hence, PAGASA has warned the public not to lower their guard in taking precautionary measures against floods and rain-induced landslides in hazard prone areas.
It will also continue to monitor the day-to-day rainfall/weather conditions and the large-scale climatic patterns that will affect the country especially on the possible impacts of the on-going La Niña, Goya assured. (Rutchie Cabahug-Aguhob, PIA 10)
