Authorities have issued a health alert as a heatwave sweeps across many provinces, with the peak "feels like" temperature in Bang Na district of Bangkok forecast to top the table at 50C on Thursday.
The "feels like" or apparent temperature is the temperature equivalent that humans feel, resulting from the combined factors of relative humidity, air temperature and wind speed. In warm climates it is known as the heat index and in cold climates it is called wind chill or chill factor.
