The Meteorological Department expected heat indices to reach dangerous levels in five areas of the country on Sunday.
The highest "real feel" apparent regional temperatures expected on Sunday were:
• 51.2°C in Phetchabun in the North;
• 46°C in Kosum Phisai district, Maha Sarakham province, in the Northeast;
• 52.7°C in Bangkok's Bang Na area in the Central area;
• 53°C in Sattahip district, Chon Buri province, in the East; and
• 51.1°C in Phuket, in the South.
The heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.
