According to the Philippine Atmospheric Geophysical Astronomical Services Administration (Pagasa), the heat index in Metro Manila could soar to a scorching 40 degrees Celsius.

In light of this, Pagasa has urged the public to take necessary precautions to safeguard themselves against the hot weather.

The heat index refers to the perceived temperature experienced by the human body when the combination of air temperature and relative humidity is taken into account.

“Those venturing outdoors today should make it a habit to carry an umbrella and stay hydrated to shield themselves from the intense heat,” advised Pagasa weather specialist Benison Estareja.

In addition, Pagasa stated that certain areas in Central Luzon, Ilocos Region, Cagayan, and Tuguegarao may also experience high temperatures reaching up to 36 degrees Celsius.

Pagasa’s forecast for Saturday afternoon indicates that most parts of Luzon will have cloudy to partly cloudy skies, with a chance of rain in the western section, particularly over Palawan.

Meanwhile, Mimaropa (consisting of Marinduque, Occidental Mindoro, Oriental Mindoro, Palawan, and Romblon) and the Bicol region will have partly cloudy skies, while generally fair weather is expected in the rest of Luzon.

Southern Leyte and Eastern Samar may encounter isolated rain showers and thunderstorms in the afternoon or evening, attributed to the presence of the Inter-Tropical Convergence Zone (ITCZ) and easterlies.

Caraga, Davao, and Soccsksargen regions are anticipated to experience light to moderate rains. (ai/mtvn)
