Conditions are ripe for an impressive avalanche cycle on the South Coast of B.C. today, according to Avalanche Canada.

A Pineapple Express weather system arriving on the coast is expected to dump 30 to 50 centimetres of snow in the mountains, and avalanche forecasters advise Thursday is a day to wait out the storm from a safe place.

The storm has also triggered a snowfall warning for Whistler and a rainfall warning for Howe Sound, with Environment Canada forecasting 15 to 20 centimetres of snow and 50 to 70 millimetres of rain by Thursday night.

Elsewhere in the province, conditions are rated from considerable to high over the coming days as the storm moves across British Columbia.

Weather warnings have also been issued for the east coast of Vancouver Island and the Columbia region.
