DEKAD NO. 27 21 – 30 SEPTEMBER 2023
Philippine Agri-Weather Forecast
The weather systems that will likely affect the whole country are the low pressure area (LPA), intertropical convergence zone (ITCZ), southwest monsoon, easterlies, and localized thunderstorms.
During the early days of the forecast period, most parts of Southern Luzon, Visayas and Mindanao will experience cloudy skies with rainshowers and thunderstorms while the remaining parts of the country are expected to have partly cloudy to cloudy skies with chances of rainshowers or thunderstorms. After this, Southern Luzon, Visayas, Zamboanga Peninsula, Northern Mindanao and Caraga will continually experience cloudiness with scattered rainshowers and thunderstorms. Fair weather condition with some chances of rainshowers or thunderstorms are expected over the rest of the country. During the latter part of the forecast period, cloudy skies with rainshowers and thunderstorms will gradually be experienced in most parts of Luzon and Visayas while the remaining portions of the archipelago will generally have good weather condition with possible occurrences of rainshowers or thunderstorms.
During the early days of the dekad, winds coming from southwest will start to prevail over Mindanao while the rest of the country will have winds coming from northeast to northwest. After this, the southwesterly wind flow will progress over Palawan and Visayas. The remaining parts of Luzon will generally experience winds from the southwest to south.
During the early days of the forecast period, slight to moderate seas will be experienced over the whole archipelago. After this, Luzon and the eastern seaboard of Visayas and Mindanao will have moderate to rough seas while the remaining coastal waters in the country will have slight to moderate seas.
ENSO ALERT SYSTEM STATUS: EL NIÑO ADVISORY NO. 3
An increased positive sea surface temperature anomaly (SSTA) was observed across the tropical Pacific, indicating a moderate El Niño. Most climate models predict El Niño will strengthen further into a strong one later in the year and will likely continue until the second quarter of 2024
El Niño increases the likelihood of below-normal rainfall conditions, which could bring negative impacts (such as dry spells and droughts) in some areas of the country which may adversely impact the different climate-sensitive sectors including the water resources, agriculture, energy, health, public safety, and many more. However, with the ongoing El Niño, enhanced Southwest monsoon season (Habagat) is favored, which may result in above-normal rainfall conditions over the western part of the country
