Talked with Jon a couple times in the last few days. He's in great spirits and feeling physically ready for the summit window approaching.
Now is when accurate, pinpoint weather forecasts take center stage. All the expeditions are jockeying for position and watching the weather forecasts with an eagles-eye. It's all about identifying when the strongest winds (jet stream) will back away from the summit allowing climbers to safely reach the summit. The photo above was taken in Camp 3 (24,100ft).
Right now, most teams will make a push for the higher camps and summit in the next 20 days. I emailed updated forecasts to Jon and his expedition leaders on the
Summit Climb expedition. They are also listening to Sherpas who intuitively understand the weather patterns on Everest from years of hard work up there. Sherpas have been higher on the mountain and know the conditions. Climbing guide Arnold Coster has his private sources of last minute weather forecasts as well added to the mix. It's a life-and-death cocktail of almost "top-secret" information.
Jon tells me he'll be making a move for the high camps early next week to get into position for a summit attempt. The weather will dictate from there. By the way, wish Jon a happy birthday! We'll celebrate when you return safely to CO!
