Warm and humid conditions prevailed across the country on Monday, with the state weather bureau reporting generally fair skies but a likelihood of isolated rain showers later in the day.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said the ridge of a high pressure area influenced Northern Luzon, bringing sunny but humid conditions, especially from midday to afternoon.
In the rest of the country, easterlies continued to affect weather patterns, resulting in similar warm conditions during the daytime.
The weather agency said Metro Manila’s temperature was expected to climb to around 33°C during peak hours.
Despite the heat, localized thunderstorms were still expected to develop, bringing brief rain showers in parts of the capital and other areas from afternoon to evening.
The agency added that the heat index in Metro Manila could range from 36°C to 37°C, which falls under the extreme caution category where heat-related illnesses may occur.
The highest heat index for the day was projected to reach up to 40°C in several areas, including Dagupan City in Pangasinan, San Jose in Occidental Mindoro, La Granja in Negros Occidental, and Zamboanga City.
Pagasa also reported no gale warning over any of the country’s seaboards and said no tropical cyclone or low pressure area was being monitored within or outside the Philippine area of responsibility.
