Environment Canada has issued a warning that a heat wave is expected to intensify on July 7, covering more than three dozen regions in British Columbia. The elevated temperatures pose a risk to public health, so precautions are encouraged to minimize exposure.
Heat warnings have been issued for much of the lower third of the province, the northeastern part of B.C., and inland sections of the central and north coasts. Some regions, such as the southern Interior, are preparing for temperatures to reach into the low 40s this week.
Initially, about two dozen warnings were issued, but they have since been expanded to cover more regions. Metro Vancouver is among the areas included, with expected daytime temperatures in the mid-30s, but cooler temperatures near the water.
The City of Vancouver has opened cooling centres in libraries and community centres in response to the heat wave. Residents are reminded of the more than 200 permanent water fountains available for use across the city.
The city is also urging residents to check on vulnerable individuals, including seniors, those who live alone, people with pre-existing health conditions, mental illness, homelessness, or limited mobility. Health partners advise that it may be unsafe for some at greater risk of heat illness to be in indoor temperatures above 26 degrees Celsius, with significantly increased risk above 31 degrees Celsius.
