Reappearance of smoke

After a almost whole summer of intense smoke in mid-southern B.C. (Boundary Area), we were treated again to the stink of forest burning last night. But this time the culprit is not a careless smoker or camper, or a lightning storm. It is our dear Forestry department, who must feel that we haven't had enough smoke already, or that we need to keep in shape for another smokey summer in 2019, or perhaps those who made the decision don't live in an area that spent the summer immersed in the blue haze. Where the carbon-reducing considerations in burning slash are, I know not, just that breathing in Sunday night's smoke brought back the memory of what a terrible summer that we had to live through, with fires in the Snowy Mountains, and Manning Park allowed to burn on with little attempt to stop them. I know a considerable amount of the smoke came from California, but the wind pattern doesn't always come from south to north. Maybe this behavior of the Forestry is good for the timber companies, but myself, and others, who have COPD or asthma, may have to sell our properties and move somewhere where we can breathe year around. I wonder what the losses in tourism are, when people avoid coming to the province because of the blue fog. I wonder if we are losing more in tourism dollars than what we are spending in fighting fires? There needs to be a discussion, as to the wisdom of letting fires burn on without much intervention, that include B.C. residents who have to bear the brunt of the blue B.C. air, and another discussion on the wisdom of slash burning in spring and fall. Enough already!

response to "Reappearance of smoke"

Ken, I'm sorry to hear you suffer from respiratory issues that are stirred up by the smoke from the forest fires. As you've noted yourself, though somewhat begrudgingly, burning excess forest fire fuel in the off-season when it's safe to do so is indeed a wise fire prevention practice. I also read that you lament letting fires burn in the summer months. I'm sure you know British Columbia is a chunk of land larger than most countries on Earth with vast, remote mountain ranges and extremely limited access to most of it. Have you thought about how incredibly dangerous it is to attempt to fight raging wildfires in these vast, steep, densely forested areas? It is virtually impossible to utilise heavy machinery, tankers and teams of fire fighters in places like this without sending them into the face of significant danger or in some cases, certain death. Manpower and machinery is simply not in enough supply to fight these battles when there are hundreds of fronts across the province. Many discussions are already had surrounding the "wisdom of letting fires burn", and I would encourage more in order to help educate BC citizens on why this is often the required response. To be clear, no one sane wants to see our beautiful forests ravaged by fire, our wildlife charred, our citizens suffering from the effects of the smoke, or the potential loss of tourism dollars many of us rely on. Despite this, we can't send people to their deaths in the middle of a mountain range in a futile attempt to curtail fires of a scale most simply cannot imagine. We CAN however make efforts to minimise availability of forest fire fuel during seasons of low risk, and we should be doing that as best we can, particularly in areas of significantly increased danger to population centers or locations of significance. This way, when peak fire season arrives, we have done as best we can to mitigate risks and limit the potential for devastating blazes. Surely anyone can understand that? Even with all these practices, with you having COPD, you may indeed be best considering relocating given the health risks posed by forest fire smoke, as the threat of these fires is not going away and most likely will only get worse. All the best to you Ken. Any chance you are related to Ron? Cheers.


Living in a blue haze becomes traumatic; the comments I made came on the heels of a reoccurrence of smoke after a long summer with no respite from the constant irritation caused by it's presence. I understand the principles of forest management, and the dangers and methodology of fighting forest fires, and don't expect that firefighters show be sent into areas that may threaten their health and lives. I do wonder, however, why B.C. does not have a larger fleet of fire-fighting tankers, such as those used in the U.S., with large capacity like the MARS flying boats. Sending in smaller units does not seem to get the job done in many cases, as the incredible dryness of the land allows fires to spread at an incredible speed, and makes me wonder why the initial blazes are not hit with larger capacity planes to knock them down before the fires are completely out of control. 2018's large fire along the west side of Okanagon Lake reached incredible proportions after a very short time, and tied up a large percentage of the total resources available after a very short time, leaving little left to contain the Snowy mountain fire, or the fire in Manning Park. It took very little time for the Snowy Mountain fire to reach from a few miles south of Keremeos to the U.S. Border. After listening to interviews in 2017 about resources being outstripped by the fires in the Cache Creek area and northward to Williams Lake and beyond, I could not help wonder whether the B.C. Wildfire Management Services are being given enough funds to properly contain and shut down these larger blazes. A shortage of equipment and resources can be just as dangerous to fire fighting personnel, as being sent into areas that are difficult to reach, and that contain "vast, steep, densely forested areas". This makes me speculate if larger air assaults would make firefighting safer for the brave souls who have to slog it out on the ground putting out spot fires that escape any air assault conducted before ground crews are set in.
I am deeply grateful to those who are on the forefront of firefighting in B.C., and wish them to have the very best resources at their disposal to carry on what must be experienced as a thankless job, with many taking their dangerous work for granted. In rereading the comments I made I realized, however, came from an emotional backlash of the months spent in the haze, which at times with fires across the border from Midway B.C., made it hard to see more than a block away, and made me overjoyed to see our 2 retardent planes from Penticton come in to help the U.S. firefighters, who had fought on for a week against a large blaze with little more air support than a helicopter and a spotter plane until the Canadian planes and crews joined the frey. With our current rather warm winter just beginning I hope for a summer of increased precipitation, and a spring of steady, but non-torrential rains, to dampen the forests, but not create destructive flooding such as that which was endured by many local in the Grand Forks area, and many other communities in B.C.
P.S. Tristan, I have no living relative by the name of Ron, my "Swansons" were mainly "prairie people", although one uncle, Dale, long- departed, made it out to what was then Haney, to marry and procure a lovely acreage and live the rest of their lives in that area. His family continues living in that community.

reappearance of smoke

Ken, do you know what a controlled burn is, or why the forest service does them? It is intended to reduce or eliminate forest fuel from under the canopy so as to reduce potential fires caused by carelessness or naturally occurring fire events

Still smoky and warm on the

Still smoky and warm on the coast, we really need some rain to clear this out. Please, can somebody order some rain?!

Not accurate at all

We have smoke from the wildfires and while that has cooled it down here in the Lower Mainland not one isolated shower or generally cool, it's quite muggy and smoky at night not comfy at all. Guess we'll see if that changes

The temps are predicted high

The temps are predicted high but not nearly as warm due to cloud cover from smoke but it's definitely not hot

Very accurate so far for summer!!

So far the FA has been very accurate for summer 2018 in the region! Although I’m impressed with how accurate it’s been I’m hoping the predictions for the rest of the summer are wrong because I want warmer weather!


I’m with ya Amanda!! Was shocked how accurate it was but, also hoping wrong for August cause I have lots of camping in mind haha

Weather predictions for May on the South Coast

They predicted for May an average temperature 11°C and rainfall of 30 mm, 20mm below average. We've had 1.5 mm and temperatures not seen before all well above average in the mid to high 20's. It's been unprecedented hot, unusually humid summer weather and no rain in what use to be the wet and dismal month of May.
