Kootenay Boundary

The freezing level is forecast to drop a bit Monday, yet the sun will still be out. Thin wet loose avalanches are the main concern on steep slopes facing the sun.

Numerous size 1-1.5 wet loose avalanches were reported on Saturday and Sunday. They were primarily running on slopes facing the sun. Expect wet loose avalanches to continue Monday as the sky clears and the freezing level rises to mountain top.

Expect surfaces to melt and weaken as the freezing level climbs to 2300 m on Monday. This will occur more rapidly on sun-exposed slopes.

The upper snowpack consists of various melt-freeze layers and the lower snowpack is strong and bonded.

• Minimize exposure to sun-exposed slopes when the solar radiation is strong.
• Minimize your exposure time below cornices.
• Back off slopes as the surface becomes moist or wet with rising temperatures.
