First smoke warning for BC went out today for a fire in the south interior discovered on August 17. And a new fire was discovered up a forest service road about two hours from Vancouver! Only two hectares, but hey, guess what? It's time for another heat wave down here! I have a feeling we're just going to stop having normal winter in a couple years and it'll be ashy rainstorms from November through March.

They're starting to do hazard reduction burns across NSW ready for our upcoming fire season. A little bit of smoke came over us but has pretty much cleared now. https://twitter.com/NSWRFS/status/1302878002053701632

Everyone was making fun of Hawaii when the volcano rolled over a few luxury vacation rentals and poor people's homes but the mainland is just entirely on fire for like 6 months of the year.

Man Musk posted:death crew refusing evac sounds about right No doubt they were dumb fucks but, if you had shovels and whatnot, could you dig foxholes in the sand and hide in those? You can move sand very quickly and build up walls which would do the job of shielding you from radiant heat. But then you'd be forever known as the guy who refused to be rescued so he could hide in a sandcastle. EDIT: As kids we'd always being digging poo poo like this at the beach

Storms often form way out in the middle of the Atlantic or just off the coast of Africa, you never hear about them because they spin off into the ocean. Check out this nhc climate page if you want to see all the tracks... https://www.nhc.noaa.gov/climo/  Rene is going to spin off into the ocean and annoy some fishermen Pryor on Fire has issued a correction as of 15:49 on Sep 8, 2020 |

An average surface fire on the forest floor might have flames reaching 1 meter in height and can reach temperatures of 800°C (1,472° F) or more. Under extreme conditions a fire can give off 10,000 kilowatts or more per meter of fire front.

Under extreme conditions a fire can give off 10,000 kilowatts or more per meter of fire front. a kilowatt will heat 1 kg of water 1C in around 4 seconds, but that's only like a quart of water. A hot tub is usually like 400 gallons, so 10MW of power will heat it 1C every ~1.6 seconds. Most pools are way bigger than that though, so the smallest pool I can find (8000gallons) would take like 30 seconds to get 1C hotter, and an olympic size swimming pool (660k gallons) would take about 44 minutes to get 1C hotter. Assuming that the temp starts at ~80C and get's uncomfortably/dangerously hot at ~105C you'd have between 12 minutes and 18 hours before the pool got too hot. I'm sure the reservoir is bigger than both of those. Unless it's a small pool you're much more likely to die from smoke inhalation or because the air is hundreds to thousands of degrees.

been kinda stressed about fires since this has been the driest summer since i moved to the west coast and it's bee crazy hot for like the past month, and now there's a big, very fast-moving fire right near where i work https://www.facebook.com/watch/live/?v=765925304203162

From 26C to 100C it would take 2.6 MWh, meaning a 10MW source would take 15 minutes. (Now we see what stupid errors I made  )

you guys should probably consider the fact that a pool is parallel to the ground and somewhat below it in your calculations before you assign the full 10 megawatts per meter of a fire front into it

We aren't even factoring in the emissivity of the pool or the nonlinear thermal absorption coefficients! Also does the fire front even last 10 minutes? I assume everything burns pretty fast and then it's just embers which won't have as much heat output.

The water is not going to heat straight through, you will have a gradient. It takes a ton of energy to change the state of the water so you should get a lot of buffer from the steam. (im ignoring the infrared part because you already knew from reading the thread to turn your pool into a swamp) e: while you are down there, you can start tunnelling towards non-fire areas of the earth and you get a few feet head start thanks to the pool
