Monthly Philippine Agro-climatic Review and Outlook

October 2022

10

  • During the month of October, the weather systems that affected the country were the southwest monsoon, intertropical convergence zone (ITCZ), easterlies, northeast monsoon, shear line, low pressure areas (LPAs), five (5) tropical cyclones, and localized thunderstorms.
  • The tropical cyclones that entered the Philippine Area of Responsibility (PAR) were Tropical Depression (TD) “Maymay” (11 – 13 October), Typhoon (TY) “Neneng” (11 – 13 October), Tropical Depression (TD) “Obet” (19 – 22 October), Severe Tropical Storm (STS) “Paeng” (26 October – 01 November), and Tropical Depression (TD) “Queenie” (31 October – 01 November). Tropical Depression “Maymay” formed in the east of Casiguran, Aurora and weakened into a low pressure area before it made its landfall. It brought heavy rains over the northeastern part of Northern Luzon specifically in the provinces of Aparri, Tuguegarao, Benguet, Isabela, Quirino, and Aurora. Typhoon “Neneng” entered the PAR as a tropical depression passed into the waters of extreme Northern Luzon as a severe tropical storm and intensified into a typhoon before it exited the PAR. Typhoon “Neneng” brought significant amount of rainfall over the northern part of Luzon that resulted into floods and flashfloods in the most areas over Northern Luzon. Tropical depression “Obet”, the third TC for October formed in the Philippine Sea east of extreme Northern Luzon as a tropical depression. Its track is likely the same as typhoon “Neneng” that passed through the waters of extreme Northern Luzon as a tropical storm. It brought moderate to heavy rains in the northern part of Luzon then exited PAR afterwards. Severe tropical storm “Paeng” started as a tropical depression outside the PAR and intensified as a tropical storm when it entered PAR. “Paeng” made multiple landfalls, its first landfall was in Virac, Catanduanes, second was in Caramoan, Camarines Sur, third in Buenavista, Quezon, fourth in Sta. Cruz, Marinduque, and fifth in Sariaya, Quezon, then in San Juan, Batangas, it traversed in the Cavite – Metro Manila area afterward it made its final landfall in Baliwag, Bulacan. It exited PAR as a severe tropical storm. TC “Paeng” brought intense to torrential rains that resulted in floods and flash floods in different parts of the country and raised Tropical Cyclone Wind Signal numbers 1, 2 and 3. In terms of agricultural damage, “Paeng” have_a total production lost amounting to Php 2,709,303,157.54 in 9 regions according to Department of Agriculture) (source: https://ndrrmc.gov.ph/attachments/article/4211/SitRep_No_14_for_STS_PAENG_2022_Update.pdf). Tropical Depression “Queenie”, the last tropical cyclone for the month entered the PAR and dissipate while coming near the east of Mindanao. ITCZ affected most areas in Mindanao that causes severe flooding, flash floods and landslides.
  • Termination of the southwest monsoon was declared last October 06, 2022, while the onset of the northeast monsoon was on October 20, 2022.
  • Generally, near to above rainfall conditions were experienced over the whole archipelago with some patches of below normal rainfall conditions in Palawan and Davao region. The top three highest recorded rainfall for the month of October were Aparri synoptic station with 1,090.5 mm of rainfall followed by Infanta synoptic station with 870.6 mm then Calayan synoptic station with 865.7 mm of rainfall.
  • Derived Soil Moisture Condition (rainfed areas):
    • Wet – Most areas of the country
    • Moist – none
    • Dry – Puerto Princesa and southern portions of Palawan

La Niña Advisory #13 was issued on 06 October 2022. La Niña continues to persist in the tropical Pacific. La Nina increases the likelihood of having above normal rainfall conditions that could lead to potential adverse impacts (such as heavy rainfall, flashfloods and landslides) over highly vulnerable areas. Adverse impacts such as floods and landslides are likely to occur over the vulnerable areas and sectors of the society.
  • Slightly below average to above average surface temperature was experienced in Luzon and Mindanao while in Visayas below average to above average surface temperature was experienced. Muñoz, Nueva Ecija Synoptic Station recorded the highest maximum temperature of 36.8°C (October 22) while the coldest temperature was recorded in BSU Agromet Station in Benguet at 13.1 (October 26). (Figure 2).
