More intense hurricanes and longer-lasting forest-fire seasons have long been associated with climate change.

But the most immediate threat to life in B.C. appears to be heat waves.

This week, the B.C. Coroners Service revised the number of provincewide deaths upward to 815 during a recent heat dome.

That's more than 300 percent higher the norm for that time of year. According to the B.C. Coroners Service, 562 of those deaths from June 25 to July 1 occurred in the Fraser Health and Vancouver Coastal Health regions.

The B.C. Coroners Service said that all the deaths from June 25 to July 1 are being investigated.

On July 2, Chief Coroner Lisa Lapointe announced that there had been 719 deaths across B.C. from June 25 to July 1.

Meanwhile, this morning, Environment Canada issued a special weather statement for Metro Vancouver warning of more hot weather.

Daytime temperatures are expected to rise 3 to 5 C later this week due to a strengthening ridge of high pressure.

"The time frame with the hottest weather will be from Thursday to Saturday," the national weather forecaster stated. "The highest temperatures are expected to be in the Fraser Valley, Sea to Sky region, and inland Vancouver Island."
