1. Side thread: With the Nooksack in "major flood" stage and its water heading north of the border (hence the evac alerts), worth considering what that can mean. Luckily we have a report from last year spelling out just what a Nooksack flood can look like.
2. Study looked at a variety of scenarios. Unclear right now which one we are looking at. We haven't yet seen Highway 1 closed, as happened in 1990, but that seems verrrrrrry possible.
3. One potential consequence: Flooding of many farm parcels with sewage lagoons.
Another: fuel sources in the way of the water may be swept away, and contaminate, floodwaters:
Pipelines: including a major pumping station near the border. This is where that pumping station is located.
6. Estimated damages in $
7. Homes: Huntingdon is the densest neighbourhood in line for flooding. The yellow dots here represent homes that were flooded 30 years ago:
8. Side thread ended. You can find this report here: abbotsford.ca/sites/default/…

Air at Siska Indian band, south of Lytton, is registering particulate numbers that are pretty incomprehensible. Image
I'm not sure about the Lytton area reserves, but prior to it being placed on evacuation order a couple hours ago, Shalalth - west of Lillooet - was offering evacuations and financial support to people needing to leave for health reasons. Image
For comparison, earlier this year, PM2.5 measurements hit 460 in New York.

NEW STORY/THREAD:
Monday Fraser Valley flood thread. But will start with this: my story on the volcano feeding the floods, the Nooksack's three forks, why snow is good, rain is bad, and a grad student's suddenly urgent thesis fvcurrent.com/article/mount-…
That story was finished late last night, after big edits by @gracekenn and @jwsthomson. To keep up with all we are doing at @currentfv, and to support us, you should subscribe at fvcurrent.com.
1. Had wondered/hoped it would be stacked a bit. There's your answer.
2. Highway clearly isn't going to open for at least a few days.

Sunday flood thread:
Huntingdon neighbourhood evacuated overnight; Nooksack forecast improves a bit. Will be updating this story here throughout the day.
fvcurrent.com/article/breaki…
Also, I'll be putting the finishing touches on a large story for tomorrow that looks at Mt. Baker's role critical role in feeding the Nooksack its floodwaters, and how that will change over the coming years.

12 C in Abbotsford. 80mm has fallen already. Another 50mm on its way. But then... the rain in Abbotsford is only a slice of the problem.

This column is less, dare I say, bad than the last one. It seems to make sense throughout. And then it gets to this. Which *again* gives away the game. Which is that Corcoran's purpose, his only purpose here, is to fight against efforts to curb emissions. That's the whole point.
Like, he is interested in finding a way to make his favourite argument, then he makes it. He says he's not making a 'cynical' argument. Which, fine. It's just backwards reasoned. And makes no sense because, as I previously pointed out, more rain/less snow on Baker is the thing.
In some imagined world where the lake was still there but this region was still heavily populated, more rain on Baker would still be a big big big problem. You're not going to move Huntingdon.

Nooksack watch thread. Let's watch the Nooksack go up. And hope it doesn't go up that fast. Here was the forecast this morning:
Nooksack at 142.82 as of 3:15pm
---
Compared to:
142.81 forecast as of 4pm.
----
So slightly above, but has only just started to rise.
Current forecast is for it to hit:
• 144.67 at 10pm
• 147.46 at 4am
• 148.47, close to peak, at 10am tomorrow.
148='moderate flood' / What that means is uncertain because the last flood moved a bunch of sediment (i.e. rocks) around and damaged banks of river.
• Rainy here in Chilliwack, but not overly so.
• Temp= 8 C & rising
• Lower the better b/c more snow, less rain.

Abbotsford just held a press conference. Mayor Henry Braun said water down 9inches in Sumas Lake yesterday. Says weather a problem. And that it's unclear how sediment from the last storm will affect the Nooksack this time round.
🚨 "The Nooksack river has experienced significant damage and sediment build up."
"Floodwaters from the Nooksack River are anticipated to cross into the west side of Sumas Prairie in the Huntingdon area."
Be prepared to leave immediately
Everyone in Huntingdon area should be ready to leave extremely quickly. Sandbagging along southern rail line to protect Huntingdon. Those in Huntingdon should go to Huntingdon Park. Will get help from military.
