On Friday, June 7, fourteen areas in the Philippines will experience Heat Index levels categorized as “dangerous,” according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA). The Heat Index, which measures the perceived temperature factoring in humidity, is expected to range from 42°C to 44°C in these regions.
The highest Heat Index of 44°C is forecasted for Maasin in Southern Leyte. Several other areas will see indices close to this extreme level. Laoag in Ilocos Norte, Aparri and Tuguegarao City in Cagayan, and Surigao City in Surigao del Norte are projected to reach 43°C. These elevated temperatures pose significant health risks, including heat cramps, heat exhaustion, and heat stroke.
Areas with a forecasted Heat Index of 42°C include MMSU in Batac, Ilocos Norte; Bacnotan in La Union; CLSU-Munoz in Nueva Ecija; Casiguran in Aurora; Virac in Catanduanes; Roxas City in Capiz; Catarman in Northern Samar; Catbalogan in Samar; and Tacloban City in Leyte. These regions are also under the danger category, and residents are advised to take precautionary measures to avoid heat-related illnesses.
PAGASA categorizes the Heat Index into different levels of danger. Indices between 42°C and 51°C fall under the danger level, where heat cramps, exhaustion, and heat stroke are probable. An index of 52°C or higher is categorized as extreme danger, where heat stroke is imminent.
In contrast to these high Heat Index levels, Baguio City and BSU in La Trinidad, Benguet, will have the lowest forecasted Heat Index at 25°C, providing a much cooler respite compared to the dangerously high temperatures in other areas.
The Heat Index is a crucial measure, especially in a tropical country like the Philippines, as it provides a more accurate representation of how hot it feels when relative humidity is considered. High humidity levels can make the air temperature feel much hotter than it is, increasing the risk of heat-related illnesses.
Residents in the affected areas are advised to stay indoors as much as possible, stay hydrated, and avoid strenuous activities during the peak heat hours. Wearing lightweight and light-colored clothing can also help reduce the risk of heat-related health issues.
In summary, with the Heat Index reaching dangerous levels in 14 areas on Friday, PAGASA’s warnings should not be taken lightly. Preparedness and caution can help mitigate the adverse health effects associated with extreme heat.
