Relentless heat sends wildfire concerns soaring across B.C.

A surge of heat over southern British Columbia will continue to keep the fire danger high this week.

We’re likely facing the warmest start to September on record for several locations of southern B.C, reminiscent of September 2022.

We’ve already seen more than 1,500 fires across B.C. this season, collectively responsible for burning more than one million hectares of land. Nearly three-quarters (73 per cent) of those fires were started by lightning, above the long-term average of 58 per cent.

As it stands, the number of lightning-caused wildfires is the highest since at least the 2008 wildfire season. As of Sept. 4, 32 wildfires remain out of control with 214 active blazes.

Hot weather will push back into the South Coast this week, with temperatures cresting above the 30°C mark across the inland sections. Locally, some areas could see temperatures reach 35°C, such as in Port Alberni and parts of the Interior.

With high dew points, it will feel muggy across the Lower Mainland, especially inland in the Fraser Valley as a southerly flow develops.

The warmest humidex record is 40 for Abbotsford in September. The humidex there reached 37 on Thursday. Folks in Pemberton endured a feels-like value of 38 on Thursday. This level of heat is likely uncomfortable for some across the region.

The South Coast looks to remain dry until next week, when a trough is set to move closer to the coast, increasing the risk of showers. No significant rainfall is forecast through the southern Interior for the next 7 days.
