Monthly Philippine Agro-climatic Review and Outlook

August 2022

8

  • During the month of August, the weather systems that affected the country were the southwest monsoon, intertropical convergence zone (ITCZ), low pressure areas (LPAs), three (3) tropical cyclones, localized thunderstorms, easterlies, and ridge of high pressure area (HPA).
  • The tropical cyclones that entered the Philippine Area of Responsibility (PAR) were STS “Florita” (August 21 – 23), TD “Gardo” (August 30 – September 01) and STY “Henry” (August 31 – September 3). STS ‘Florita” made its landfall on the vicinity of Maconacon, Isabela then traversed the landmass of Northern Luzon and in some areas in Central Luzon, then exited in Burgos, Ilocos Norte. Significant rains resulted to flooding/flashfloods and landslides over Northern Luzon while in some parts of western Luzon and Visayas have experienced moderate to heavy rains due to the enhanced Southwest monsoon. TD “Gardo” did not have any direct impact to the whole country and was merged with the circulation of STY “Henry”. Likewise, STY “Henry” did not landfall anywhere in the country but the Tropical Cyclone Warning System (TCWS) was raised to number 2 in most areas in Extreme Northern Luzon that experienced gustiness and moderate to heavy rainfall while light to moderate rainfall in the western Luzon were experienced due to the enhancement of the Southwest monsoon.
  • Generally, the whole country received near to above normal rainfall conditions except in Pangasinan, Pampanga, Zambales, Bataan, Iloilo and SOCCSKSARGEN where below normal rainfall condition were observed.
  • Derived Soil Moisture Condition (rainfed areas):
    • Wet – Ilocos Region, most areas in Cagayan Valley, Cordillera Administrative Region, Central Luzon, most areas in National Capital Region, CALABARZON, Mindoro provinces, Marinduque, Romblon, Northern Palawan, most areas in Bicol Region, most areas in Western Visayas, Central Visayas, Northern Samar, Eastern Samar and Southern Leyte, Dipolog, Bukidnon, most areas in Davao Region, most areas in Caraga, and Bangasamoro Autonomos Region in Muslim Mindanao.
    • Moist – Itbayat, Calapan, Masbate, Iloilo Province, Samar, Leyte, most areas in Zamboanga Peninsula, Davao City and Pasay City
    • Dry – rest of the country
  • Generally, near to cooler than average surface temperatures were felt in most parts of the country except for some areas in Central Luzon, some areas in CALABARZON, Zamboanga and Bukidnon where warmer than average surface temperatures were experienced. Hinatuan recorded the highest maximum temperature of 35.6°C (August 21) while the coldest temperature was recorded in BSU Agromet Station in Benguet at 14.5°C (August 11).
  • La Niña Advisory #11 was issued on 04 August 2022. La Niña condition persists. Most climate models suggest that La Niña condition will continue until Dec-Jan-Feb 2023 55 - 70% chance of persistence with ENSO-neutral thereafter. La Niña increases the likelihood of having above normal rainfall conditions. Adverse impacts such as floods and landslides are likely to occur over the vulnerable areas and sectors of the society.
