Conditions
It appears that there has been some retreat in some of the areas of old snow in recent days, but significant areas of old snow remain in a number of places. There is also some new snow also lying higher on the mountain, with a layer of snow above about 800m. The new wet snow was only a few centimeters deep, but it appeared to result in almost complete cover above about 850m, making conditions slippery underfoot in a number of places. Although there was only a little of it, it was enough to transform the hazards in a few places, resulting in more wintery hazards returning to a number of places higher up on the mountain.

The old snow was generally firm, with a soft surface, but completely soft in many places. The new snow was soft, wet and slippery, and uncertain underfoot.

On the Llanberis path the significant snow started towards the bottom of Allt Goch (about 800m). It was easy enough to walk the path at first, but by the top of the hill conditions felt significantly more challenging. The new snow had completely hidden the path above Allt Goch, and again raised the possibility of a long slides with serious consequences in this area of the path.

The PyG and miners' paths were not walked below Bwlch Glas, but despite the poor visibility it was possible to see that there was still considerable steep snow covering the path completely when going up to the bwlch on these paths.

Above Bwlch Glas on the Llanberis, PyG, miners and Cwellyn (Snowdon Ranger) paths when heading for the summit there were several areas of old snow, but also new snow completely covering the route.

A number of old drifts were seen along steep edges, some corniced, which are worth giving a wide berth.

A cloudy and dry day to begin with, with a very strong gusty wind. Snow and rain up to the summit level for a period through the middle of the day, with the temperature at the summit close to freezing. Sunny intervals and light showers descending the western side of the mountain while cloud still sat on the summit.

Snow was seen being transported by the variable and gusty wind higher up on the mountain during the observations.

Essential equipment
Suitable seasonal walking equipment, including lighting (such as a headtorch or two each).

Carrying an ice axe and mountaineering crampons will offer safer options on the mountain.

Carrying goggles (such as ski goggles) will offer a means of protecting the eyes to see more easily in order to travel more safely on the mountain.

Additional Information
On the Friday of the report the forecast suggests that the temperature on the summit will be close to, or below freezing throughout the period until the next report on Tuesday, cooling further to start the new week. The temperature at the summit is forecast to be as low as -3ºC (feeling like it is as low as -10ºC at times).

It is also forecast to rain at times, with snow likely higher on the mountain over the weekend, but more widespread on the mountain at the beginning of next week. Snow looks likely on Saturday night and into Sunday morning, and increasingly likely from Monday onwards. The snow will likely fall under the influence of, and be blown around by, significant winds from the south and east.

This means that conditions will be increasingly wintry in the coming days, with snow (and ice) likely on significant parts of the mountain. Periods of very poor visibility where paths will disappear under snow and be impossible to follow are likely.

Note: it appears that some of the Met Office's mountain location forecasts, e.g. for the summit of Yr Wyddfa, at the time of writing the report give unusually low forecasts for wind speed, and any such forecasts should be checked against the Met Office mountain area forecast for Eryri, and other forecasts to avoid getting the wrong impression of conditions on the mountain.
