Mountain Weather Seminar March 31
At the Seattle Mountaineers Clubhouse, No registration necessary. No fee. Members and non-members welcome. Weather is the biggest limiting factor for outdoor recreation in our marine climate. Understanding and -- more important -- predicting our mountain weather is a critical skill. Come learn from an expert. Mike Fagin is founder of Washington Online Weather (, a Mountaineers Alpine Scramble grad and a professional weather forecaster. Mike will give us an overview of "machinery" of western Washington weather - what forces give us wet or dry conditions? He will share his favorite sources of accurate mountain forecasts to check before leaving home. Then he will talk about forecasting in the field. What do various cloud formations portend? Does that shift of wind direction mean anything? Is that gray sky OK or is it time to turn tail and scat? If it's wet here, will it be better east of the passes? Mike Fagin forecasts not only in our area but also for major Himalayan expeditions. Reduce your mountain misery quotient. Learn skills to help you keep dry and happy.
