For the week ending 13 Dec 2025: A rare week for us, but perhaps, with climate change, becoming less so. Measurable amounts of precipitation fell every day: At 65 mm, the total rainfall SWE was 3 X the avg weekly longterm SWE in Dec (20.4 mm). With 2 weeks still to go, we're approaching 82% of the avg longterm monthly total precipitation SWE. I attribute this week's conditions to atmospheric rivers sweeping into the coastal Pacific Northwest, the first on Sun-Mon, the second on Wed. These events have caused disruptive flooding in various communities in BC's Abbotsford -Sumas Prairie lowland and also in Washington State, as the Nooksack River is overflowing its banks. Major highways that link coastal BC to the rest of BC and Canada have been closed. This is the second time in 4 years that dangerous, disruptive atmospheric rivers have struck. One of our chicken yards is slippery and muddy. Puddles are visible in places where the ground cover can't absorb the water. On daily walks, I observed pooling water in ditches, and misty temperate inland rainforest conditions have prevailed. I'm still seeing elk, deer, flickers, crows, and geese. Ski resorts in the area are open, and the closest, 45 min drive away, has reported a snow-base of 135 cm. I'm still concerned about the lack of snowpack development at elevations below 1500 metres.
