KATHMANDU, Nepal (AP) — A team of Nepalese guides on Tuesday became the first expedition to scale Mount Everest during this year’s climbing season, setting the ropes for the hundreds of climbers who will follow.

Nepal’s Department of Tourism said the specially chosen team of expert guides fixed ropes up to the 8,850-meter (29,035-foot) summit during favorable weather Tuesday. Weather conditions had been poor in recent days.

There are 41 different teams with a total of 378 climbers who have been permitted to scale the world’s highest mountain during the spring climbing season. There are an equal number of Nepalese guides helping them to get to the summit.

There are usually only a few windows of good weather near the summit in May for climbers to attempt to scale the peak.
