May 2020

5

  • During the month of May, the weather systems that affected the country were the easterlies, ridge of High Pressure Area (HPA), frontal system, intertropical convergence zone (ITCZ), localized thunderstorms, low pressure area (LPA) and tropical cyclone (TC) “Ambo”.
  • TC Ambo has brought stormy weather conditions with gusty winds over eastern Visayas and Luzon during 10 -17 May 2020. Cloudy skies with scattered rainshowers and thunderstorms prevailed over extreme Northern Luzon due to frontal system. Similar weather conditions were experienced over Mindanao due to ITCZ and LPA. Partly cloudy to cloudy skies with isolated rainshowers and thunderstorms were experienced over the rest of the country.
  • Derived Soil Moisture Condition (rainfed areas):
  • Wet – Cagayan, CAR, Baler, CLSU, Infanta, CVSU, Northern Samar, Eastern Samar, Surigao del Sur;
  • Moist – Batanes, Nueva Ecija, Casiguran, NCR, Alabat, Laguna, Camarines Norte, Albay, Catanduanes, Sorsogon, Dumangas, Leyte, PCA, Surigao del Norte;
  • Dry – rest of the country
  • Generally, near normal to above normal rainfall conditions were experienced over the eastern parts of the country. The western parts of Luzon and Visayas, Dipolog, Butuan, and SOCCKSARGEN experienced below normal rainfall conditions while Coron had experienced way below rainfall conditions (Figure 1). Catarman, Northern Samar has recorded the highest total monthly rainfall (463.1 mm).
  • Near to above average surface air temperatures were felt over most parts of the country with way above average temperature over Pampanga (Figure 2). The highest maximum temperature in the month of May has reached 40.0°C in Tuguegarao, Cagayan (May 4) while the coldest temperature of 15.2°C was recorded in Baguio City (May 16).
  • ENSO-neutral condition persisted during the period.
  • Land and Seedbed Preparation – (irrigated rice and corn fields, other cash crop plantation, small and medium farm areas)
Even during the MECQ most of the farmers continue to prepare the land for irrigated and rainfed rice and corn crops, as well as for other high yielding cash crops in different selected farm areas of the country.
