Fair - Timing or intensity of solar radiation is uncertain

Weather Forecast

Unsettled conditions are expected for Friday as the ridge of high pressure rebuilds over the south coast. A mix of sun and cloud is expected with moderate NE winds in the alpine. Freezing levels are forecast to reach around 1300m. On Saturday, sunny conditions are expected with freezing levels reaching around 1500m. Alpine winds are forecast to be moderate-to-strong from the NE. On Sunday, very similar conditions are expected.

Avalanche Summary

Some small solar-triggered activity was reported on Monday and no new avalanches have been reported since. Avalanches are generally not expected on Friday but could be possible on steep south-facing slopes if we get more sun than expected.

Snowpack Summary

A dusting of new snow may have buried the previously variable snow surface which may have included wind-pressed surfaces or old wind slabs, a sun crust on all solar aspects, surface hoar, surface facets, and/or up to 5 cm of soft snow over a widespread supportive rain crust in wind sheltered areas. The snowpack is generally strong and well settled. However, large cornices may become weak with daytime warming.
