Forecast Philosophy“As a mountaineer I know how critical an accurate mountain weather forecast is for a successful summit bid and for the group safety. Timing is everything. I have been doing this for myself and other mountaineers since the 1970’s.”

—Michael Fagin, lead forecaster for West Coast Weather,

Forecast Models Used:The following forecast models are used to analyze the weather patterns of the major climbing region and prepare the weather forecasts:

  • European Centre for Medium-Range Weather Forecasts (ECMWF)

  • Navy Operational Global Atmospheric Prediction System (NOGAPS produced by the Fleet Numerical Meteorology and Oceanography Center)

  • Global Forecast System (GFS) from NCEP -National Centers for Environmental Prediction, U.S. The goal of this GFS model is to replace the AVN and the MFR models

  • National Centre for Medium Range Weather Forecasting Ministry of Science and Technology, Government of India. Used for Asian forecasts

  • Global Forecast System-Taiwan Central Weather Bureau (CWB)

  • Unified Model from the U.K. Met. Office

Quotes from clientsOur expedition took place in a somewhat ‘uncharted’ season on Everest, the post-monsoon. The weather during the autumn is significantly less observed than in the spring. Your forecasts were excellent and that is not an easy task when forecasting from October 1 till November 1. Not only was I impressed with these forecasts but also our climbing Sherpas’ found your forecasts very valuable and that was the first time they liked an “outsider’s” forecasts.”

—Wally Berg

“Thanks for your custom forecast for our summit attempt of Mt. Hunter in Alaska this past spring. It seems like my schedule these days is such that I do not have time to go places in North America and sit around for weeks waiting for good climbing weather. For Mt Hunter our request was simple, “give us a 4 day seam of dry weather for Alaska in May.” As you know it was snowing there the early part of the month and we delayed our planned departure several times based on information from you that indicated continued bad weather. We were patient, knowing that being flexible would pay off and then in the middle of the month you provided information that was not yet available on the free weather services that indicated a 4 day seam of dry weather was coming. With that information, my climbing partner and I jumped on a plane to go to Anchorage and then on the bush plane that took us onto the glacier. Just as you predicted, sunny weather prevailed for over 4 days.”

—Steve Swenson

“I was using my sat phone to call an expert named Michael Fagin in Seattle for precision forecasts. On May 7 I got the good news, decreasing winds at 8000 meters and dry weather from the north is on its way.”
