Hong Kong to Review Warning System After Record Heat Triggers Lowest Alert The sweltering heat that engulfed Hong Kong over the weekend has raised uncomfortable questions about the city's ability to protect its outdoor workers from extreme temperatures.
A record breaking 36. 9 degrees Celsius (98. 4 Fahrenheit) was recorded, but the normally reliable heat stress warning system failed to trigger an alert.
Experts point out that Hong Kong's heat stress index focuses on relative humidity and wind speed rather than direct sunlight, a major contributor to heat related illnesses.
