The team has been at base camp for the past three days. Yesterday’s acclimatization hike took them to 18,000 ft. Mike posted a great update on Facebook this morning which summarizes the team’s plans for the next couple of days.
The sun just hit the tent here at base camp which means it’s time to crawl out of the down bag. Tomorrow morning [Thursday pm, MDT], we’ll be moving camps to Advanced Base Camp (ABC), with an overnight at an intermediate camp. As you can imagine, weather is a big factor in our success. Many of you know Joel Gratz, the founder of OpenSnow, but you may not know that he has been instrumental in getting us to the top of many mountains all over the planet. Once again, Joel is working with the expedition team to help us find good weather windows to move up the mountain. Here is today’s weather update for Cho Oyu:
Overall: Pattern is pretty steady through the 24/25th, then it changes. This likely means decreasing high altitude wind speeds starting around the 25/26th, and weakening even further by the 29th.
Winds at high altitude: Moderate on Thursday, weaker on Friday (~40kts), increasing on Saturday then strong Saturday night through about the 24th.
Snow: Normal afternoon showers on Thursday, lower chance of snow on Friday, then snow chances increase again Saturday and Sunday. Monday, Tuesday, and likely Wednesday look like little to no snow, then perhaps more snow next Thursday and Friday.
Recap: Friday (4/18) has weakest winds of the next week. Next Mon & Tue (4/21,4/22) should be the driest.
Stay tuned for additional updates!
