Overview
When forecasting future weather conditions, you analyze the same weather variables (precipitation, wind, air temperature, and cloud cover) but use weather forecast models to predict how they may change in the future. Choose a model that works well in your area, preferably a mesoscale or high-resolution regional model.
Most avalanche weather forecasts focus on the next 24 hours. However, longer-range forecasts of up to 48 hours or more are needed when, for example, planning long-range travel or future avalanche hazard reduction work.
This table outlines the standard upper-air constant pressure levels to use based on the elevation of your mountains. Choose the appropriate model forecast maps to approximate mountain elevations and interpolate between pressure levels to create forecasts as necessary.
