Monthly Climate Assessment and Outlook
La Niña-like conditions continue 
in pdf

 
Oceanic and atmospheric indicators had reached weak La Nina levels in October 2016 (PAGASA termed as borderline La Nina), but this was not sustained. However, La Nina-like conditions continue, as impacts have been seen
in some flood- and landslide-prone areas in the country. It is likely that ENSO-neutral conditions will prevail in December-January-February 2017 season.

 

The weather systems that affected the country during the month were the Northeast (NE) Monsoon, tail-end of the cold front, low pressure areas (LPAs), easterlies and the passage of Typhoon (TY) “Nina” (Dec. 22-27).  TY “Nina” made eight (8) landfalls that brought strong winds and excessive rains in MIMAROPA, CALABARZON and Bicol Region. Estimated damages to infrastructure amounting to 83 million pesos (mostly roads and river control facilities) were reported in the provinces of Marinduque and Oriental Mindoro, as stated in the NDRRMC Situational Report No. 7.

Rainfall assessment for the month of December showed that near to above normal rainfall conditions were experienced in most parts of the country, with some patches of below normal rainfall over Nueva Ecija, Leyte, Sultan Kudarat, Agusan del Norte and Maguindanao.

Slightly warmer than average surface air temperatures were observed in most parts of the country during the month. Ranges of temperature recorded were as follows; mountainous areas of Luzon: 13.0°C – 26.4°C; rest of Luzon: 17.0°C- 34.7°C; Visayas: 21.0°C – 34.2°C; mountainous areas of Mindanao: 16.0°C – 33.0°C; and rest of Mindanao: 21.5°C – 35.6°C. 

Outlook in January 2017

The expected weather systems that will affect the country in January are the NE monsoon, LPAs, intertropical convergence zone (ITCZ), tail end of cold front and the occurrence of one (1) tropical cyclone.

Rainfall forecast for the month indicates that the country will generally experience near to above normal rainfall condition, except for the provinces of La Union, Bataan and Cavite that will likely experience below normal rainfall condition.

Slightly cooler than average surface air temperatures are likely over the mountainous areas of Luzon while slightly warmer than average temperatures are predicted over the rest of the country. Predicted ranges of temperature are as follows: 9°C to 28.5oC over the mountainous areas of Luzon, 16°C to 36oC for the rest of Luzon, 20°C to 35oC over the Visayas, 15°C to 34oC over the mountainous areas of Mindanao, and 19°C to 37oC over rest of Mindanao

PAGASA will continue to closely monitor significant climate phenomena and updates shall be issued as appropriate. Meanwhile, concerned agencies are advised to take precautionary measures to mitigate the adverse impacts of this phenomenon especially in flood- and landslide-prone areas. For further information, please contact the Climatology and Agrometeorology Division (CAD) at telephone numbers 434- 0955 or 435- 1675.

PREVIOUS DRY SPELL/DROUGHT ASSESSMENTS

Cooler than average sea surface temperature anomalies (SSTAs) of at least -0.5 °C has persisted since July-August- September season. Although both ocean and atmospheric indices had reached weak La Nina levels in October (PAGASA termed as borderline La Nina), this was not sustained, as reflected by recent westerly wind anomalies and weekly SSTAs  that were within the neutral range.  In the meantime, La Niña Watch is still in effect as La Nina-like conditions continue.

The weather systems that affected the country during the month were the Intertropical Convergence Zone (ITCZ), Northeast (NE) Monsoon, low pressure areas (LPAs), easterlies and the passage of Tropical Storm (TS) “Marce” (Nov. 23-28) with track crossing over Visayas area and brought moderate to occasionally heavy rains and thunderstorms along its path resulting to floodings and landslide. Furthermore, TS “Marce” has made multiple landfall over areas of Surigao, Leyte, Cebu, Iloilo and Calamian Group of Islands. Damages amounted to a total of Php1,500,000.00 for infrastructure and around 65 hectares of palay was reported (NDRRMC Situational Report No. 4).

Rainfall assessment for the month of November showed that near to above normal rainfall conditions were experienced in most parts of the country.  Some provinces of western and central Luzon, including Metro Manila and southern Palawan and most parts of central Mindanao which received below to way below normal rainfall.

Surface air temperatures were observed to be slightly warmer than normal in most parts of the country. Ranges of temperature recorded were as follows; mountainous areas of Luzon: 13.0°C – 26.2°C; rest of Luzon: 17.6°C- 35.5°C; Visayas: 20.8°C – 34.2°C; mountainous areas of Mindanao: 17.0°C – 34.0°C; and, rest of Mindanao: 21.9°C – 35.3°C.
