With temperatures expected to soar to around 30°C or higher over an extended period, Environment Canada has issued a warning to local residents to exercise caution during the heat wave.
Conditions will rapidly warm up on Wednesday, and it is expected the heat will last until Friday when temperatures dip to the mid-20s and there is a chance of rainfall. Overnight temperatures will come close to 14°C.
However, the extreme heat conditions could return over the weekend following the short break on Friday and continue through the first week of August.
The warning advises the public to consider rescheduling outdoor activities during cooler hours of the day, take frequent breaks from the heat, drink plenty of non-alcoholic and non-caffeinated beverages to stay hydrated, and not leave any person or pet for any length of time.
High body temperatures can lead to heat stroke, heat exhaustion or even death, with young children, seniors, pregnant women, and those with existing health conditions most at-risk. Other symptoms of a heat-related illness include a lack of sweat, vomiting, rapid breathing and heartbeat, dizziness, confusion, fainting, and unconsciousness.
