DEKAD NO. 19-09      March 21-31, 2019

Philippine Agri-Weather Forecast
The weather systems that will affect the whole country are the northeasterly wind flow, ridge of high pressure area (HPA), tail-end of a cold front and easterlies.

Generally, fine weather condition will prevail over the whole country during the early days of the forecast period except for some isolated rainshowers over the eastern sections of Southern Luzon, Visayas and Mindanao. However, the provinces of Cagayan and Isabela are expected to have cloudy skies with light rains during the end of the first half of the dekad. The rest of the country will have partly cloudy skies. Visayas and the eastern sections of Luzon and Mindanao will have cloudy skies with isolated rainshowers during the early days of the second part of the dekad while the remaining portions of the archipelago are expected to have fair weather. During the latter part of the forecast period, Northern Luzon will experience cloudy skies with rainshowers while the rest of the country will have good weather with some chances of isolated rainshowers.

During the start of the dekad, winds from the east to southeast will blow over the northern, central and eastern sections of Luzon. The rest of the country will have winds coming from the northeast to east. For a moment, northeasterly winds will prevail over Northern Luzon during the latter part of the first half of the dekad while the rest of the archipelago will experience winds from the east to northeast. During the second half of the forecast period, winds from the east to southeast will blow over northern, central and eastern sections of Luzon while the rest of the country will have winds from the northeast to east.

During the early days of the forecast period, the eastern seaboards of the country will have moderate to rough seas while the rest of the archipelago will have slight to moderate movement of coastal waters. However, the northern and eastern seaboards of the archipelago are expected to become moderate to rough during the end of the first half of the dekad. The rest of the country will have slight to moderate seas. During the second half of the forecast period, the eastern seaboards of the country will continue to have moderate seas while the rest of the archipelago will have slight to moderate seas. However, the northern and central portions of Luzon are expected to have moderate to rough seas at the latter part of the dekad while Visayas, Mindanao and the rest of Luzon will have slight to moderate seas.

Weak El Niño is present in the tropical Pacific.
Farm Advisories

The PAGASA ENSO Alert System issued El Niño Advisory with weak El Niño condition which is now present and expected to continue up to the second quarter of 2019. Water stress alters the physiological and metabolism of plants and reduces the quality and quantity of yield. Irrigation is essential to ensure successful crop production in water stressed farms or regions. Selection of drought resistant plants or drought tolerant cultivars reduces the effect of water stress to farmers during this time of the year.

The farmers are reminded also that dry and clean environment is necessary, since, aside from pneumonia, parasites rank second in causing heavy mortality in animals. In hot humid places, animal housing must be well ventilated.
