A total of 28 areas across the Philippines are expected to experience heat indices falling under the “dangerous” category on Saturday, May 17, the state weather bureau warned.
According to the latest forecast released by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa), the highest projected heat index will be felt in San Jose, Occidental Mindoro, at a searing 45 degrees Celsius. This same location also registered the country’s highest heat index on Friday, reaching 47°C.
Under Pagasa’s categorization, heat indices from 42°C to 51°C are classified as “dangerous,” meaning they may cause heat cramps and exhaustion. Prolonged exposure can also lead to life-threatening heat strokes.
San Jose, Occidental Mindoro tops danger list
Pagasa emphasized that the extremely high heat index in San Jose reflects the severity of the dry season. The agency has advised residents to avoid outdoor activities during peak noon hours and stay hydrated.
In a public advisory, Pagasa said residents in the affected areas must take immediate precautions, especially children, the elderly, and people with pre-existing health conditions. These groups are most vulnerable to the effects of extreme heat.
The weather bureau encouraged the public to seek shaded or air-conditioned environments, wear lightweight clothing, and refrain from strenuous activities.
Other areas expected to reach dangerous levels
Following closely behind San Jose, Pagasa listed several locations expected to experience heat indices between 42°C and 44°C, including:
- 44°C: Aparri (Cagayan), Cubi Point in Subic Bay (Olongapo), Infanta (Quezon), and Pili (Camarines Sur)
- 43°C: Laoag (Ilocos Norte), Dagupan (Pangasinan), Tuguegarao (Cagayan), Zamboanga City (Zamboanga del Sur), Iloilo City, and Davao City
- 42°C: Pasay City, Bulacan, Cavite City, Tanauan (Batangas), Puerto Princesa (Palawan), and Legazpi (Albay)
These readings are taken from stations that factor in temperature and humidity, reflecting the apparent temperature that people actually feel, rather than just the air temperature.
Pagasa meteorologists noted that even urban locations like Ninoy Aquino International Airport in Pasay could reach 42°C, heightening concern for city dwellers constantly exposed to heat-retaining concrete and poor ventilation.
Public urged to stay alert and cautious
With high temperatures continuing to scorch various parts of the country, government agencies like the Department of Health have reiterated the dangers of heat-related illnesses. Schools, workplaces, and local government units are being reminded to implement safety measures and promote awareness.
The extreme heat is expected to persist until the rainy season officially begins, which Pagasa said may happen late in May or early June.
