Heat Index Expected to Reach Dangerous Levels
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has issued warnings about the dangerous heat index expected across 30 areas on Friday, May 23. With temperatures soaring, the heat index is projected to climb as high as 46 degrees Celsius. Local experts emphasize the importance of awareness as the dangerous heat index poses health risks.
The highest heat index is anticipated in Aparri, Cagayan, reaching 46°C, followed closely by Dagupan City in Pangasinan at 45°C. Several other cities are also under alert, as the risk for heat-related illnesses increases with rising temperatures.
Areas Facing High Heat Index
Cities with the Highest Readings
Aside from Aparri and Dagupan City, a heat index of 44°C is expected in Laoag City, Ilocos Norte; Tuguegarao City, Cagayan; and Olongapo City, Zambales. These regions should take precautionary measures to minimize exposure to the sun and stay hydrated.
Additional Regions at Risk
Thirteen other locations may experience a heat index of 43°C. These include Batac (Ilocos Norte), Bacnotan (La Union), Echague (Isabela), Baler and Casiguran (Aurora), Camiling (Tarlac), Cavite City (Cavite), Tanauan (Batangas), Infanta and Alabat (Quezon), Daet (Camarines Norte), Masbate City (Masbate), and Catarman (Northern Samar).
Meanwhile, twelve areas are forecasted to have a heat index of 42°C. These are Pasay City (Metro Manila), Sinait (Ilocos Sur), Bayombong (Nueva Vizcaya), Iba (Zambales), Los Baños (Laguna), San Jose (Occidental Mindoro), Cuyo (Palawan), Legazpi City (Albay), Pili (Camarines Sur), Iloilo City and Dumangas (Iloilo), and Catbalogan (Western Samar).
Health Risks and Safety Recommendations
PAGASA classifies heat indices between 42°C and 51°C as dangerous due to the increased likelihood of heat cramps and heat exhaustion. Prolonged exposure to these conditions may escalate to heatstroke, especially among vulnerable groups such as children, the elderly, and those with pre-existing health conditions.
Community leaders said, “People should avoid staying outdoors for long periods and drink plenty of fluids to stay safe.” Local experts also recommend wearing light clothing, seeking shade, and monitoring symptoms of heat-related illnesses to prevent serious health issues.
Given these warnings, residents are urged to take immediate precautions to mitigate the effects of the dangerous heat index. Awareness and proactive measures are vital to protect public health during this period of intense heat.
