Five minutes can be a long time in the Australian backcountry. Most forecasts for weather, snow conditions and avalanche hazard cover a wide geographical area. It is common for conditions to vary from one part of the region to another. Regional variabilities and uncertainties in forecasts make verifying the conditions an important step in your daily process. The aim is to determine whether the conditions are different than expected and if so, make appropriate changes to your plan. These changes may range from aborting the trip to adjusting the plan to a lower risk option with greater emphasis on slope evaluation and maintaining good travel habits.
It is good to verify the conditions before leaving the trailhead, however unexpected hazards often only become apparent during travel, in which case modifying the plan to take these changes into account is a must. You may find few options are available and that you are already exposed to the hazard. Communication amongst your group becomes all-important and is key to implementing a change or retreat.
Factors which can affect your plan include the amount of new snow, temperature, wind loading, visibility, snow conditions, snowpack instability, avalanche occurrences. As you travel, keep observing and evaluating, and communicating your thoughts to the others in your group. Stay alert and open to changing the day’s plan. No plan should ever be set in concrete in the backcountry!
