Abstract: 

The effect of a range of standard meteorological variables used in conventional avalanche forecasting on avalanche probability for the Craigieburn Range is analysed. While the effects of temperature and windspeed variables on avalanche probability are similar to those established for other areas, it is shown that total precipitation and precipitation intensity values required for instability in the Craigieburn Range are low. This is believed to be a function of the windiness of the Craigieburn Range snow environment. Critical meteorological values f o r avalanche formation are proposed.
