The risks posed by extreme heat are more significant for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors. Some of the effects of heat illness include swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions.

Last week, the province’s public safety minister, Mike Farnworth, said a new warning system is ready to go with new protocols on how to issue heat alerts.

The protocol lays out the daytime maximum and nighttime minimum temperatures that would trigger the heat bulletins.

If a region is expected to exceed those ranges for two consecutive days it will trigger a heat alert, while if it is expected to last three or more days it will trigger a heat emergency, Farnworth said.

The public is also being urged to visit the province’s PreparedBC website for more resources on how to manage extreme heat.

Temperatures rose to a peak of more than 40 C in many parts of the province.

In its report, the BC Coroners Service said it investigated more than 800 deaths during the week of June 25 to July 1, 2021, and later found 619 to have been heat-related.
