Because of Everest's great height, instead of watching the sky, climbers keep an eye below for clouds moving up the mountain.

From the time they reached Basecamp, Byron and the rest of the Everest 2000 team were constantly checking weather conditions. Dr. Dave Irvine-Halliday installed a permanent weather monitoring station at team headquarters and Dr. Virginia Robinson tabulated the information, sending it back daily to the website.

The computerized system recorded temperature, barometric pressure, humidity and wind speed and direction. It was on loan from the Vulcan Tourism and Trek Station.

The team is grateful to the Vulcan Tourism and Trek Station for the loan of the weather monitoring equipment.
