InnisfilWeather.Com Information Supplied By Environment Canada. High Heat and Humidity/Heat Wave/Humidex The elderly and individuals with pre-existing medical conditions are particularly vulnerable to heat stress. A heat alert system links mortality rates with weather data. A Humidex or High Heat and Humidity Special Weather Statement are issued when a threshold for temperature and humidity are exceeded. Special heat alerts or heat emergencies may be also issued by larger cities in addition to those issued by the weather centre. These alerts trigger a city to respond by distributing water to vulnerable sectors of the population, and to open air-conditioned facilities to the public for relief from the heat. A Environment Canada Humidex Advisory is issued when temperatures are expected to reach or exceed 30°C and the humidex values are expected to reach or exceed 40. Humidex values represent the effect which high humidity and high temperatures have on the human body. The higher the humidex, the harder it is for perspiration to evaporate and cool the body. Safety Tip: When the temperature goes up, slow down. Drink plenty of water, your body needs it to keep cool. Adjust to activity gradually. It takes four to eight days for your body to acclimatize. |
