Heat wave topples temperature records in southern B.C., as conditions raise wildfire fears

The latest on the heat wave:

• 17daily heat records were broken on Monday, and the 10 hottest places in Canada were all in B.C.
• Officials worry the high heat followed by an incoming coldfront will make wildfire season even worse.
• Outreach workers are distributing water, hats and sunscreen to people in Vancouver's Downtown Eastside.
• B.C. Hydro says a new record for electricity demand in August was set on Monday, likely driven by residents usingair conditioners and fans.
• Seasonal temperatures are expected to return Wednesday.

The 10hottest communities in Canada on Monday were alllocated in British Columbia and forecasters expect thesizzling temperatures will continue for at least a few more daysacross the province's Interior.

The Fraser Canyon communities of Lytton and Lillooet both brokethe 40 C mark on Monday, with Lytton reaching 41.4 C and Lillooetonly slightly below at 40.7 C, marking the first time the 40 C threshold has been recorded broken anywhere in Canada this year.

Environment Canada says Lytton and Lillooet were among 17 communities from Vancouver Island tosoutheastern B.C. that set daily heatrecords on Monday. OthersincludedKamloops (37.8 C), Pemberton (39.5 C), Pitt Meadows (33.5 C), Port Alberni (37.5 C), Vernon (37.3 C) and Whistler (36.7 C)

With high humidity, the weather agency warns many areas could feel hotter than 40 C.

Environment Canada says overnight lows across southern B.C.didn't dip much below 20 C, further complicating the wildfiresituation while adding to the risks facing elderly and vulnerablepeople who can't escape the ongoing heat wave.

Provincial power utility B.C. Hydro said Tuesday that it also set a new record for the highest peak hourly demand in August on Monday night.

B.C. Hydro said in a statement that consumption reached over 8,400 megawatts, with a heat wave usually adding 1,000 megawatts of power use, equivalent to switching onone million portableair-conditioning units.

"While the demand for power is higher-than-average with the hot temperatures, B.C. Hydro wants to assure its customers that its renewable and reliable, hydroelectric system can meet the additional demand," the statement reads.

Winds help fuel fire concerns

The conditions are a concern for the B.C. Wildfire Service, which says around 380 wildfires are currently burning across the province, 162 of which are considered out of control.

Eleven are classified as fires of note, meaning they are highly visible or threaten people or property.

Fire information officer Sarah Budd says a cold front from the northwest is due Thursday and will hitthe high-pressure system bringing all the heat, creating strongwinds, dry lightning and the potential to add to the province'salready challenging wildfire season.

"Unfortunately, this hot weather is also coming along with relatively high winds,'' Budd said in an interview Tuesday.
"We could see gusts up to 50 or 60 kilometres per hour today out of the west.''

Budd saidthe service is prepared for the Kamloops and Southeast fire centres to be the most affected by Thursday's weather forecast, both for new starts and an increase in fire activity on existing wildfires.

Outreach for vulnerable in DTES

An outreach team for the Union Gospel Mission (UGM) in Vancouver hasbeen working in the city's Downtown Eastside to ensure people areaware and are prepared to cope with the heat spike across parts ofB.C.

UGM spokespersonNicole Mucci says those who are experiencingmental illness orhomelessness or who have chronic health conditionsare most at risk of illness and death during such heat waves.

She says staff have been handing out water, hats and sunscreenand are encouraging people living in the Downtown Eastside to seekout cooling stations during the day and stay in shelters at night.

B.C.'s Ministry of Emergency Management has said a repeat of the2021 heat dome, which claimed more than 600 lives, is not forecastbut it warns people to take precautions to stay out of the heat,drink water and limit activity.

The coroner's report from the 2021 event said most of the deathshappened indoors and most of those who died were adults aged 60 and over who didn't haveair conditioning. It said the number of deaths for those living inpoverty was "lower than may have been expected."

"It is important to learn from the people living in those areas,such as those living in the Downtown Eastside of Vancouver,"thereport said. "Lived experience must inform community strategies forprevention from planning through implementation."

Seasonal temps return Wednesday

Mucci agreed, noting it is also important to remember that manypeople in such areas live in "precarious"housinglike single room occupany hotelsand don't always haveaccess to fans or air conditioning.

She said the UGM's housing team has worked to ensure itsshelters are equipped with cooling areas.

Mucci said they've noticed many groups within the community nowwatch to ensure residents are prepared and protected.

"Whether that's folks who are unhoused, folks who areexperiencing addiction, perhaps those with mental illness, or thosewho are maybe elderly or disabled, and just letting them know thathot weather is coming,'' she said.

Environment Canada urges people to be aware of heat illnesses andits symptoms, including swelling, rash, cramps, fainting, heatexhaustion, heat stroke and the worsening of some health conditions.

Bulletins from the weather office show much of the coastal regionwill return to seasonal temperatures by Wednesday, but central andsouthern regions of the province will feel the heat a day or twolonger.
