Environment Canada issues widespread warnings as intense heat wave settles over B.C.

Heat wave arrives in Metro Vancouver The first heat wave of the summer is rolling into Metro Vancouver and other parts of B.C.

More than two dozen regions in British Columbia are under warnings as a heatwave expected to push temperatures into the low 40s in the coming days settles over much of the province.

Environment Canada has issued heat warnings for more than two dozen regions, saying a "building ridge of high pressure" is bringing extreme temperatures to much of the province.

The warnings cover much of B.C.'s bottom third, inland sections of the central and norths coasts, as well as the northeastern part of the province.

They expanded Saturday afternoon to include Metro Vancouver and the Fraser Valley, with the weather office saying elevated temperatures with daytime highs in the mid-30s are expected to begin Sunday.

While it says temperatures are forecast to moderate by the middle of the week, "the timing is currently uncertain."

Provincial Health Minister Adrian Dix is urging residents to figure out where their homes are coolest and keep windows and blinds closed during the hottest times of day.

Dix also says vulnerable people are at high risk during heat waves, as are seniors.

Environment Canada and local medical health officers say they expect an increase in health and safety risks from heat and are advising the public to take precautions.

The weather office says early signs of heat illness could include fatigue, thirst, headache, unusually dark urine, and can rapidly evolve into life-threatening emergencies.

It says people should drink plenty of water and to check on neighbours and anyone who lives alone.

Anyone experiencing a heat-related emergency is encouraged to call 911.
