Summary
Confidence
Low - Due to the number and quality of field observations
Weather Forecast
A low to the west of Haida Gwaii will spin off small amounts of precipitation and strong SW winds into the forecast region Sunday afternoon and early Monday with a brief break in the weather Monday afternoon. We can expect 5 to 10 cm through Monday. Tuesday will see another pulse of moisture bringing 10 to 15cm of precipitation and moderate to strong SW winds at ridge tops. The freezing level should stay around 350 metres through the forecast period.
Avalanche Summary
No reports of avalanche activity in the forecast region
Snowpack Summary
In general, the early season snowpack is shallow and weak. Developing storm slabs are sitting on a mix of crusts and weak facetted crystals or surface hoar in some parts of the region. The southwest of the region sounds like it has the most snow, and probably the most wind with the new snow. We have some reports of a weak facetted base layer in the north of the region where recent temperatures were quite cold during the arctic outbreak. If you get out into the mountains, please submit your observations using the Mountain Information Network.
Problems
Storm Slabs
Moderate to strong ridge top winds with precipitation will build storm and wind slabs.
Use ridges or ribs to avoid pockets of wind loaded snow.>Avoid freshly wind loaded features.>Minimize exposure during periods of heavy loading from new snow, wind.>
