The weather systems that will affect the country are northeast monsoon, tail-end of a cold front, and low pressure area (LPA).

During the early days of the forecast period, the regions of Eastern Visayas, CARAGA and Davao will experience rains and isolated thunderstorms while the regions of Ilocos, Cordillera, Cagayan Valley, Central Luzon and Bicol will have light rains. The LPA is expected to bring rains and isolated thunderstorms over Mindanao, Visayas and MIMAROPA at the midst of the decadal period.

The rest of Luzon will have light rains while the rest of the country will have partly cloudy to cloudy skies with isolated rains.

Moderate to strong northeasterly winds will blow over the whole country during the first half of the ten-day period. Afterwards, Luzon will gradually have moderate to strong winds coming from northeast to east while the rest of the country will have light to moderate winds coming from the east.

The seaboards of the whole country will be moderate to rough during the first half of the forecast period. After that, the coastal waters over Luzon will be moderate to rough while the rest of the country will have slight to moderate seas.

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

 
La Nina-like conditions continue, as above normal rainfall were recorded in most parts of the country. Global climate models show that El Nino Southern Oscillation (ENSO)-neutral condition is expected by February 2017, continuing through the first half of 2017.

The weather systems that affected the country during the month were the Northeast (NE) Monsoon, tail-end of the cold front (TECF), low pressure areas (LPAs), easterlies, ridge of high pressure area (HPA) and the passage of Tropical Depression (TD) “Auring” (January 7-8). TD “Auring” developed inside the Philippine Area of Responsibility (PAR) and made landfall over Surigao del Norte.

Analyses of rainfall for the month of January showed that most parts of the country received near to above normal rainfall, except over the provinces of Abra, Batanes and most areas in Ilocos Region, which experienced way below to below normal rainfall conditions. Flooding/flashfloods incidences were reported in many areas of Cagayan de Oro, Bukidnon, Lanao del Sur, Cebu City, Butuan City and CARAGA region due to continuous heavy rains brought about by LPAs and TECF.

Slightly warmer than average surface air temperatures were observed in most parts of the country during the month, with surges of cold temperatures over the mountainous areas of Luzon. Recorded average temperatureranged as follows; mountainous areas of Luzon: 13.1°C –22.0°C; rest of Luzon: 19.2°C- 32.0°C; Visayas: 22.9°C – 30.3°C; mountainous areas of Mindanao: 18.8°C –28.2°C; and rest of Mindanao: 22.4°C –32.4°C. 

Outlook in February 2017

Weather systems that will likely affect the country during the month are the NE monsoon, LPAs, TECF, easterlies, ridge of high pressure area (HPA)and the occurrence of one (1) tropical cyclone.

Rainfall forecast for the month of February indicates that most parts of the country will generally experience near to above normal rainfall condition. On the other hand, Cordillera Administrative Region (CAR), Ilocos Region, provinces of Tarlac, Zambales, Palawan, and Negros Oriental will likely experience way below to below normal rainfall condition.

Slightly cooler than average surface air temperatures are likely over the mountainous areas of Luzon, while slightly warmer than average air temperatures are predicted over the rest of the country. Forecast range of temperatures in February are the following: 15.4°C–36.9°Cover lowlands of Luzon, and 10.0°C–27.2°C over the mountainous areas;18.5°C–37.5°C over the Visayas; 18.2°C–36.7°C over the lowlands of Mindanao while 13.5°C–32°C over the mountainous areas.

PAGASA will continue to closely monitor any significant climate phenomena and updates shall be issued as appropriate. Meanwhile, concerned agencies are advised to take precautionary measures to mitigate its adverse impacts especially in flood- and landslide-prone areas.

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.
