Unless I missed it (we were evacuated from Puyallup so I have not read all your blogs) you haven't mentioned that this was a classic "rain on snow" event. The 70 inches of snow you mentioned during the first days of the year stored a lot of water. Then the system switched to a Pineapple Express and the warmth and the rain melted a good deal of snow (depending on the elevation.) So a significant amount of the water in our rivers came from melting snow from previous storms, not just from the 12+ inches in this storm. Since this is a well-described phenomenon I would think your readers would be interested in it.

All I can say is it is now 9:30 pm here in Kingston, and the real rain is just starting to hit us here. There were showers off and on this afternoon, but to turn on the TV and see the rain amoints that were being received throughout Western Washington? Wow.

All I can say is I hope those in flood areas can get away and stay safe.

Chris...How much does a radar site cost? What are the major reasons UW/private money can't put up what we need?

I know, dumb question, and I'm not even a blonde, but I'd like to know.

I'm all for coastal radar, but why the gratuitous trade-off against some solar collectors that begin to give City Light some experience with this form of distributed generation before the solar revolution hits Seattle. Which will be sooner than many think. If we want to point a finger at something, how about a $307,000,000,000 guarantee of the obligations of Citygroup, with zero due diligence and no Congressional involvement in the decision? That's approximately 200,000 times more than the solar panels cost.

2009-01-07T15:05:00.000-08:00

Seems like the rain shadow has pretty much collapsed. We had very little rain on Bainbridge up until about 30" ago. Now it's raining hard but not as windy.

Hey Cliff, when can we expect a return back to cooler temps with drops in the freezing level for the mountains along with snow?

Hey Cliff. Can we expect this rain shadow to collapse tonight? Some forecasters are calling for it, others aren't. What do you think?

2009-01-07T13:34:00.000-08:00

Raining hard at Holden Village, 48.2N 120.75W (Elev. 3224 ft), avalanches have closed the road and much of the 130" of snow that we have had is now turning to slush. We can see a few avanches from the village and we know that we have a huge possiblity for more.

Our biggest danger is the snow slidding off of the buildings (roofalanches we call them). We have to route our paths to avoid the tons of ice and snow that slides off in this warm weather. Warm weather here about 38 degrees and pretty ugly for this time of year.

Uncanny rain shadow here in between Poulsbo and Silverdale on the Kitsap Pen. as well as 50 degrees. All of the 12 inches of snow is gone. Only the bottom of Frosty is left. I am very thankful that we are perched on a ridge with no major rivers around.

I talked to someone in Centralia today who owns a business down there. He was flooded 13 months ago and from the looks of it, they will have the same situation again. The good news is they acted quicker and had U-Hauls lined up in front to move stuff out.

We had major rain east of renton, and over through may valley last night. Today, there is still a bit of rain there and in Issaquah as well. On SR900 this morning, the drainages were raging like a small river, and we had flooding on the roads in a few spots. One guy was outside cleaning the drainpipe that runs under his driveway.

We had huge fallen tree limbs in our back yard this morning...glad nobody was outside when they fell.

Good idea, cleaning out the storm drains. I really think the reason the snow melt was SOOOOOOOO uneventful was because people were told to clean storm drains.

With all of the fallen debris, people need to continue keeping their storm drains clean. I know this won't stop all flooding, but it will certainly prevent some.

Another gloomy, gloomy day in the shadow. Weather all around me, but gray clouds and wind where I am at. I find this weather super depressing. I hope something shifts soon.

2009-01-07T12:36:00.000-08:00

Josh, no arctic intrusion late next week. Long range models do not show anything like that. BUT as long as there is an amplified ridge, it is a possibility in the long range. Many long range forecasters think it could happen, especially Ed Berry, who said 4 weeks before we got our cold that the Pacific Northwest would get arctic air. He now thinks a similar pattern is likely (not saying it would be two weeks long with record snow, maybe more of a normal arctic outbreak).

2009-01-07T12:25:00.000-08:00

Just took visitors on the long route to grocery store via looking at the Newaukum and Chehalis rivers. We are likely to be stranded on our hilltop for a couple/few days. I fear a number of our businesses will not survive a 2nd record flood in 13 months. Newaucum is still flowing freely into the Chehals, which has about 5 feet or so before it starts going over the road. Collateral damage will hit us for about $1000, a pittance compared to what so many face. Rob

Holy cow! The Queets is up to 87,800 cfs. The 53-year record had been 61,400 in 2002. I can't imagine how big it will be tomorrow!

No rain and 53˚F here in Woodinville. Wind is still heady. Little Bear Creek has run over in the Basset Pond area (they have 165th closed through there because of it).

And have I mentioned how much I love this blog lately? Because I do, I really really do.

2009-01-07T12:14:00.001-08:00

Bellingham was simply moderate rain off and on yesterday until I slept at midnight. This morning I woke to schools closed, power outages and road flooding in totally unexpected intersections.

Sure enough, overflow stream water was running in many unexpected major streets. Stormwater Retention Ponds that have never seen water were full to overflow. A jet-ski was reported in one low-lying urban intersection. Many roads are closed.

Years ago, I analyzed 10-years of 15-min local rain-data, looking for local "design storms." The worst 24-hour rains would never be described as "storm" -- they were "continuous boring drizzle" sometimes compounded by saturated surface or snow-melt.

Fact is I never found any search definition for my "design-storm" other than total 3, 6, 12 and 24-hr accumulated rainfall.

Thanks for your many blog insights.
