There will be a lot of snow this winter, however the Pineapple Express may cause some of it to melt. Does the Pineapple Express effect help inthe formation of climbable ice?
A Pineapple Express is driven by a strong, southern branch of the polar jetstream and is marked by the presence of a surface frontal boundary which is typically either slow or stationary, with waves of low pressure traveling along its axis. Each of these low pressure systems brings enhanced rainfall.
The conditions are often created by the Madden-Julian oscillation, an equatorial rainfall pattern which feeds its moisture into this pattern. They are also present during an El Niño episode.
The composition of moisture-laden air, atmospheric dynamics, and orographic enhancement resulting from the passage of this air over the mountain ranges of the western coast of North America causes some of the most torrential rains to occur in the region. Pineapple Express systems typically generate heavy snowfall in the mountains and Interior Plateau, which often melts rapidly because of the warming effect of the system.

Have to say I am quite skeptical of this idea. Certainly wouldn't plan for a weekend, that's for sure, due to crowding issues - even parking, and especially room at the ice. On a positive note, I'm not sure much energy has ever been put into seriously exploring the idea of ice farming there.

I've lived here for 17 years now. I've heard this plan sooo many times it's ridiculous. Never gonna happen. It's funny too, all the "planners" are never local. They head back to LA/Bay after a day of ice and think they have a brand new idea. Never gonna happen.

As long as there is a good thaw/freeze cycle over the season.

Does anyone know the current conditions of East Sierra ice? e.g., Horsetail falls and Lee Vining? Thinking about travelling up from San Diego next week but want to check conditions.

Check with Doug Nidever, "The Mountain Guide". He just posted some great Lee Vining ice climbing on Face Book.

Because of the (now) 4 year drought - all the new ice has been harvested into tanks for future water use.
Don't waste your time coming up here at this/ or any other time in the near future. Thank you.
