Help Move the Christmas Trees

The Snoqualmie Valley Venturing Crew’s Christmas Tree lot is located in the Kimball Creek area and they are preparing for flood waters to possibly cover the lot’s location at the corner of Snoqualmie Parkway and Railroad Ave.

They are looking for community members to help move 250 trees into a truck provided by Littlejohn Logging at 7PM tonight. The trees are heavy and it is wet and super muddy. Volunteers are advised to wear rain gear and gloves.

UPDATE |  December 8, 2015 – 4:30PM

The City of Snoqualmie said the Snoqualmie River is predicted to rise to 52,333 cfs by Wednesday, December 9th at 4AM and stay at that level until 10AM Wednesday, but all roads and bridges were open as of Tuesday evening at 4:30PM.

The city does not expect flooding of greater downtown Snoqualmie, but says there may be more backflow into Kimball Creek than the recent flood because of the longer-term, high flood level lasting several hours. (4AM to 10AM).

Sign up for the City’s Emergency Alert System in case evacuation notices are issued. Sand and sandbags are available at the King Street parking lot at the corner of Railroad Ave SE and SE King Street for residents. (Please bring a shovel).

ORIGINAL STORY

Are you ready to see Snoqualmie Falls running strong again? Here we go AGAIN.

After a little break Monday evening, December 7, 2015, the rain ramped up overnight and according tofalls weather forecasters, is expected to stay steady, sometimes heavy, through possibly Wednesday morning.

The jet stream has dipped south bringing the words “Pineapple Express” back into the forecast – meaning it’s tapped into warmer air and tropical moisture. Freezing levels are also up, which means it’ll rain in the mountains and melt that new snow into our rivers. 3-7 inches are predicted in the Cascades by Wednesday.

So you guessed it. That means the Snoqualmie River will be on the rise once again. In fact, as of Tuesday morning,  King County was predicting the river could crest higher than in any previous storms over the past month – at near 50,000 cfs near the Falls Wednesday morning and later Wednesday evening it could crest at around 60,000 cfs near Carnation.

A Flood Watch is in place for the Snoqualmie River and a Flood Warning was issued for the Tolt River near Carnation.

And it’s not just lots of rain – it’ll be windy, too. A Wind Advisory was issued, running through Tuesday afternoon. Oh, and the National Weather Service says all the rain of late, and with this latest storm, is making steep hills unstable and warns of an increased risk of mudslides.

By later this week the temperatures cool and freezing levels rise, with snow returning to the Cascades and just our typical rainy season in the lowlands.

    50K cfs is not minor! It will be a phase 4 flood and many of us in the low lands of Snoqualmie will have basements full and water around our houses.
