- The weather systems that will likely affect the country during the month of May are the easterlies, low pressure areas (LPAs), ridge of high pressure area (HPA), Intertropical Convergence Zone (ITCZ), localized thunderstorms, and one or two (1 or 2) tropical cyclone (TC) may enter or develop inside the Philippine Area of Responsibility (PAR).
- Generally, near normal rainfall condition is expected over the whole archipelago (Figure 4).
- For the month, near to warmer surface temperature will be experienced over the whole archipelago except for slightly cooler temperature which is expected over Romblon, Mindoro provinces and Camarines provinces. Warmer and humid weather conditions are expected to be experienced. The public and all concerned government agencies are advised to take precautionary measures to minimize heat stress, optimize the daily use of water for personal and domestic consumption, and prevent any accompanying health risks associated with this climate condition.
- Luzon will have extreme temperature range of 15.0ºC – 28.1ºC for upland farms while 18.8ºC – 40.0ºC for other farms in Luzon; the lowland farms in Visayas will have 21.6ºC – 37.2ºC; while the upland farms in Mindanao will have 16.0ºC – 35.2ºC and 21.4ºC – 38.3ºC for lowland farms.
- El Niño Southern Oscillation (ENSO) Alert and Warning System: EL NIÑO WATCH.
Recent conditions and model forecasts indicate that El Niño may emerge in the coming season (June-July-August) at 80% probability and may persist until the first quarter of 2024.
