LATE SUMMER CONDITIONS - AUGUST 31, 2015

Late August and early September can produce a variety of weather patterns compounded by shorter, cooler days. Conditions may be dry today, winter tomorrow, dry by the end of the week. This is a condition report that you should expect to hear until we move into a more predictable weather pattern. Climbers should expect that the likelihood to encounter afternoon storms in the Tetons to be fairly high. These storms can create and maintain alpine conditions like snow, ice and verglas. Remember that rockfall hazard increases with precipitation. Keep an eye to the sky, stay mindful that conditions are constantly changing up high and come prepared for anything.  Groups of over 3 climbers will take quite a bit longer for an ascent and could put the group in jeopardy of being caught in an afternoon storm, please plan your route options carefully. Be prepared for cold ascents in the morning hours.
