7 areas to experience danger level heat index on Thursday, Nov. 12

MANILA — Seven areas in Palawan, Visayas, and Mindanao may experience a danger level heat index of 42 degrees Celsius on Thursday, according to PAGASA.

Heat cramps and heat exhaustion may be possible among individuals exposed to these conditions in the following areas. 

• Butuan City
• Coron, Palawan
• Cotabato City
• Dipolog City, Zamboanga del Norte
• Dumangas, Iloilo
• La Carlota City, Negros Occidental
• Zamboanga City

Prolonged exposure to such conditions could also lead to heat stroke.

Heat index refers to the temperature perceived by the human body when humidity is factored in.

The high heat index values are attributed to the warm and humid easterlies, which blow from the Pacific and prevail over southern Luzon, Visayas, and Mindanao.

Aside from warm weather, the easterlies also bring scattered rains over parts of Calabarzon, Bicol Region, and Mimaropa.

Thunderstorms may also develop later in the afternoon or evening in Eastern Visayas and parts of Mindanao.

Meanwhile, the weakening northeast monsoon or amihan will continue to affect northern and Central Luzon, bringing relatively cool conditions, particularly at night and in the early morning.

Light rains will also be experienced over the eastern portion of Cordillera and Cagayan Valley.

Since the start of the 2026-2027 amihan season, the lowest temperature recorded so far was 10 degrees Celsius, in La Trinidad, Benguet on Nov. 9.

Beginning Friday, the easterlies may once again become the dominant weather system, with warm and humid conditions expected to persist during the monsoon break.

No weather disturbances are expected inside the Philippine area of responsibility through the end of the next week.
