Alberta Flood Watch 2014

[Acey]

Emergency alert is out.

Stream levels are rising and will approach or may exceed bank full. Flooding of areas adjacent to these streams may occur.

The much above average snowpack combined with the above average temperatures over the past few days have caused the water levels in the creeks in Kneehills County to rise rapidly and overtop the banks in some locations. The snowpack in the Paddle basin is similar to conditions from last spring, and with the warm temperatures over the past few days has caused the water levels in the Paddle basin to rise rapidly. Conditions similar to last spring are expected in the Paddle basin where the Paddle River overtopped the banks in some locations, causing water to flow into the fields adjacent to the river. The River Forecast Centre has been in communication with the counties and there is no immediate concerns regarding homes or public infrastructure.

Fish Creek was raging pretty good this morning.

Please mother of god don't let Calgary flood again

[BlackArcher101]

We would still need a lot of precipitation during the melt to flood. The snow pack alone wouldn't be enough.

[OldDutch]

Yes, we probably won't have a clue for at least a month how it is shaping up. Last year was caused by a freak 3 day rain storm that the professional models didn't see coming days before. So I think we should sleep easy for 30 more days then white knuckle it into July.

[Dion]

June is flood month so it's too early to be making any kind of predictions. Besides there will have to days of heavy rain mixed in with the melt for there to be any flooding.

uh how big is a cubit again?

[Schraderbrau]

It's unfortunate but flooding has just become part of June in southern Alberta.

[Raekwon]

Nose creek in Airdrie has spilled its banks already, it has flooded a bit of the park. Nothing to call home about... Yet

[morgin]

Is limited flooding now a good sign that the melt is happening over a longer period of time and there might not be as much left come June? Or is it entirely too early to tell?

If your thinking about mitigating risk on the main bow and elbow rivers, the more that comes down and melts in april and early may, the less there is to run off in late may in june. but it doesn't really matter that much. Last year there was average snow pack and averagish run off before late June. What really matters is walls of rain were moving from east to west and then stopped on this side of the mountains. All it did was poor for 2 days straight. I remember driving through it on the way to Kananaskis 2 days before the flood and had to reduce speed to about 35km/h because the water couldn't clear off my windshield fast enough. And it did that for 2 days non stop in large parts of the foothills.

So the start of this thread is quite sensationalist to me, except for those affected by small streams generally upstream of what everyone in Calgary is going to be concerned about.

Last year, I thought they were saying that the main problem was an extremely high groundwater level prior to the rain starting. Here is what I am talking about: http://www.theglobeandmail.com/news/...ticle12792249/

An excerpt from The Last Testament (@TheTweetOfGod):

"Four digits a palm, seven palms a cubit, six cubits a reed, two reeds a nindan and ten nindans an aslu."

So roughly a metre.

[Ironhorse]

Seems appropriate here on multiple levels

Nah, lots less. The original version of it was elbow to fingertips, but there was also a version (long cubit) that was elbow to fingertips plus a hand-breadth. The various versions all come out to somewhere between 45 and 55 cm.

[Acey]

Significant water pooling here in Edmonton already, heavy rain expected throughout the day. There will be some localized flooding.

God: "I'm going to destroy the world."

Noah: Right! Am I on Candid Camera?

Noah: How you gonna do it?

God: "I'm gonna make it rain for a thousand days and drown 'em right out."

Noah: Right! Listen to this, you'll save water... Let it rain for forty days and forty nights and wait for the sewers back up.

God: "Right!"

[polak]

$100 that High River floods... Again.

Dion: Used to love that Cosby album.
