"Tomer is simply the only one I would ever trust or use for weather forecasts on a big mountain expedition."

Tomer Weather Solutions

Teams that use my weather forecasts lower their overall risk and reach the summit more often.

Teams that use my forecasts are able to plan 8 days in advance.  This includes summit day, high camp rotations, and gear needs.

Teams that use my forecasts are more confident with peace of mind, and often spend less time on the mountain.

EXAMPLE, Denali, AK: Worst weather on Earth.  But, in my opinion forecasts from the NPS/NWS & Mountain-Forecast can't be trusted on Denali.    

Why you need it

My forecasts put Teams on summits.   My track record over the last 10 years is proof with over 50 world-wide mountaineering & skiing expeditions under my belt and a summit success rate of 98%.

I present the best summit windows including all the Pros and Cons.  But, I always defer to the Team on the mountain.   

You can't trust the forecasts you see on the internet.  They are automated, lack quality control, and are void of critical nuances that you find in the mountains.  

These are not bulk forecasts.  I don't use zip code or point-and-click forecast gimmicks.  Each forecast I deliver is distilled and tailored for the client.  This kind of expertise leads to highly informed decision making.  

My strategy is to find the right tool for the Mountain.  I don't use 10 different forecast models.  I know which ones perform best.  I understand the forecast biases for each Mountain.

My imagination is an asset.  I'm also a mountaineer so I can imagine what conditions are actually like on the mountain.  I have the pulse of the climber.
