4:26 PM: Following up on our midday coverage of water and mud trouble – more weather news this afternoon. First, three National Weather Service alerts you should know about:

*The Special Weather Statement about slide risk, mentioned in our earlier coverage too.

*Another Coastal Flood Advisory for the early-morning high tide tomorrow – the water could be at least a foot higher than predicted because of weather factors.

*Wind Advisory for 8 am-3 pm tomorrow, with sustained wind from the southwest 20-35 mph and gusts to 50 mph.

But the mud is today’s trouble. If you’re using the main Vashon Island ferry dock, for example, here’s a problem:

The King County Transportation Department sent word of “a significant landslide that occurred this afternoon on 103rd Avenue Southwest near the Vashon Ferry Terminal parking lot. Crews are working to channel ferry traffic onto Vashon Highway Southwest instead of 103rd. Crews estimate it will take about eight hours to clear debris from the road. Travelers in the area should expect delays.”

Meantime, Ted Ellis sent this photo of mud along Seola Beach Drive:

Ted says, “This is one of three different slides … and part of the road looks like a pretty big wall of mud might come down.” We’re off to check on a few other things … more to come.

4:54 PM: We went back to West Marginal Way SW, a short way north of Highland Park Way, and discovered SDOT crews are still there:

One to two SB lanes are blocked there as crews work on water and debris trouble, so southbound traffic is being diverted into the center lane for a short distance. We have also gone by a trouble spot on which reported this morning – Delridge at Myrtle; the northbound lane is still fairly well puddled.

5:50 PM: We also went to Seola Beach Drive for a look at the slide mentioned above. There are indeed multiple spots with signs along the southbound side of the road, in the section that’s greenbelt on both sides – here’s the most-sizable slide spot on the slope:

It’s not blocking a travel lane, so far.

10:55 PM: King County’s Brent Champaco sent this update on the Vashon slide:

103rd Avenue SW on Vashon Island near the north ferry terminal will remain closed until 5 a.m. tomorrow morning (Friday, Feb. 10) … From 5 a.m. to 9 a.m. the roadway will be open to northbound traffic only in order to accommodate ferry rush hour traffic. At 9 a.m. the roadway will close so clean up crews can continue their work. Clean up is taking longer than expected due to the amount of debris including a large tree.
