Recent Observations:
- A whopper of a storm earlier this week brought upwards of 2 feet of fresh snow to the forecast area. This snow fell within a 24-36 hour period on Monday and Tuesday
- Two large avalanches have been observed, both in the Eddy mountains on east/northeast facing slopes, near and above treeline. One was snowmobile triggered, the other natural, both occurring on 3/29. These slides failed on older melt-freeze crusts with a weak layer of graupel sandwiched in between the new and old snow
- A decent size loose wet avalanche was reported on Black Butte, also on 3/29
- On the east side of the interstate in the Mount Shasta / Gray Butte zones, no avalanches have been observed or reported
- Wind has been predominantly light out of the south/southeast, averaging 8 mi/hr with gusts to 20 mi/hr over the past 3 days
- Temperatures have averaged 19° F, with a low of 9° and high of 31°
- Preserved powder exists on northerly facing slopes above 6,500 feet
- The fresh snow has received 2 days of settlement, approximately 7 inches. Yesterday, the snow received a good baking. Variable crusts on sun kissed slopes are likely today
- Near treeline on Mount Shasta, 205 inches of snow remains on the ground. At Castle Lake, 180 inches. Mount Eddy, 170 inches. Ash Creek Butte, 175+ inches (snow depth sensor buried)
Mountain Weather:
The forecast area remains under west/northwest flow aloft. Light showers across the area are expected today. A front arrives this evening, slowly moving onshore. With westerly flow, the bulk of the precipitation will be along the coast and coastal ranges, as well as western Siskiyou County, where up sloping effects are the greatest. Snow levels will be around 2,500 feet. Westerly wind will increase this afternoon. Another round of mountain snow is expected through the day Saturday. Longer term, rain and snow showers will continue.
