Rain Ending over Puget Sound

Just a brief note...as the precipitation band now pushes southward (however, the flooding is yet to come for many locations since it takes time for the precipitation to move down the rivers).

Here is the total rain at 11:30 AM. A band of over three inches across N. Seattle and over the eastern suburbs, and over 4 inches for the Kitsap. Much less to the north.
Nearly eleven inches at Quinault! 7.3 inches at Cushman Dam. 4.2 inches at Verlot Ranger Statoon. Darrington and Skykomish about 4.5 inches. The totals in the mountains are impressive, but don't equal those of the REALLY big events.

Looking at the IR satellite loop on the UW atmospheric sciences website from the past few hours, you can see the serious rainshadow band along the east slopes of the Cascades - the whole "cle elum" effect thing going on. We're not getting that here in White Center, that's for sure...

Only 3/4 of an inch out at my station in the "Shadow" in Sequim, but the solar readings haven't gone above 100 w/m^2 in 36 hours!

3.82" here on North Beacon Hill Seattle for the 24 hour period ending at 11AM. A December record here (36 years of record).

3.91" at 11:30 am here near Phantom Lake Elementary (East Bellevue). We're about 200' above Lake Sammamish, so no immediate flooding for us, but the lowest part of our sidewalk is under water.

North Admiral in Seattle totaled a whopping 4.5" from 11 a.m. to 11 a.m. Funny how some locals received such differing amounts.

Okay, we've had the snowstorm, we've had the (flooding) rainstorm, now if we can get the windstorm out of the way we're done for the rest of the year!

Wettest location I could find. Note the 48 hour total of more than 12 inches.

rainfall report: pretty darn wet!

Models, satellites and forecast teams did a great job. More than 72 hours advance notice of the event. Plenty of time for disaster preps etc. No real big surprises. Another good example of why it is good to invest in models and satellites. Radar is nice but not relevant to advance planning for flooding.

Relying on my unreliable, plastic, stuck in the ground rain gauge I've measured 4.4 inches in our back yard north of NE 75th in near View Ridge in Seattle. The back yard floods briefly during such events, and did this time, too. That will have siphoned out through the soils by tomorrow morning.

Still, over all I know that in my decades in the Northwest around Seattle I've seen much more impressive rivers of rain fall, sometimes for several days.

I would like to know how much of this fell as snow at and above the snow level in the higher elevations. I can't rely on my rain gauge to tell me that, or even accurately forecast it, but it seems that they had to have gotten 24 plus inches above 7,000 feet. Including the last several days I would hazard to guess that the heads of the southwest glaciers on Mt Rainier, like Tahoma, Puyallup, Nisqually, etc, must have gotten 4 feet of snow.

Right or wrong, Cliff?
