Conditions
Additional snow had fallen on the mountain since the last report, with considerable snow now lying on the mountain, with changes and developments already beginning during the day today,

On the way up the Llanberis path today the walking was initially relatively easy even though the path was completely covered by snow, with the snow on the path firm and compacted, but soft enough on its surface to offer a good grip for stiff boots. Traveling higher up the mountain there was more cover of soft snow and drifted snow, with wide areas of deep soft snow, and some areas of drifted snow over waist deep. There were also areas of thin snow on the northern face of the mountain where the snow had been scoured by the wind.

There was widespread evidence of snow that had been moved under the influence of the north and north-westerly winds over the past week, but also  active drifting today under the influence of a south-westerly wind. This means that wind transported snow exist in places sheltered from wind from a wide variety of directions, with the possibility of a windslab on a wide variety of slopes.

Various specific dangers were seen developing or existing on the mountain.

The area of the Llanberis path which traversess above Cwm Hetiau above Clogwyn station (after going under the railway bridge) was loaded with snow, with the path being narrow and steep for a section above a considerable precipice. The new fence for protecting the Rainbow Beetle was doing a good job of anchoring the snow for the time being, but already the drifts are deeper than the fence in places, with additional snow drifting and beginning to lie above the height of the fence.

Above Allt Goch there were large areas where the path was banked out with snow, with slopes below the path also covered in snow, and parts of the railway below also banked out. Although the snow was relatively soft for the moment, circumstances resemble those that have caused fatal accidents in this area in the past. It is possible that this danger will increase as the surface of this snow hardens in the coming days.

Above Allt Goch there were also areas of snow that were completely white, with no rocks or other features reaching the surface of the snow. This means that there were periods of walking the 'path' without any visible features at all to follow in the fog and blizzards, where it was necessary to rely completely on navigation techniques only to travel on the mountain. Similar circumstances may exist in the coming days.

At Bwlch Glas there was evidence of extensive drifting. Although it was not possible to observe the features in full due to poor visibility and circumstances at the time, it appears that a significant cornice is developing at this point where the  PyG path and the miners's path climb into the bwlch. It would be necessary to travel through the drifts and a possible cornice here to reach Bwlch Glas on the PyG path and on the miners' path.

A windy day, with cloud lying higher on the mountain. The day started dry, with lighter periods, but with increasing precipitation during the afternoon. Snow was still falling higher on the mountain, with sleet below around 550m and rain below around 350m when walking down the mountain.

On the way down a significant thaw had begun in the rain and sleet. Despite this, almost all of the path was still under snow, but the snow low down was wet, slippery, and slushy.

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 to facilitate safer travel.

Additional Information
On the Tuesday of the report the forecast suggests that the temperature on the summit will be below freezing throughout the period until the next report on Friday, while thawing and re-freezing will occur at lower levels. The temperature at the summit is forecast to be as low as -4ºC (feeling like it is as low as -16ºC at times).

Precipitation is also predicted at times, with showers, and more significant snow at other times (with more significant snow most likely tonight (Tuesday night) and Thursday night into Friday). There will also be strong winds at times, with the direction of the wind varying considerably.

This means that conditions on the mountain will continue to change and develop in the coming days, with snow thawing lower on the mountain, but with the possibility of the wet snow re-freezing and turning hard and icy at times. Higher on the mountain additional snow will develop, with the wind affecting the snow significantly, with new snow falling under the influence of the wind, but also the snow that is already lying being moved and changed under the influence of the significant winds from various directions, resulting in drifts building up on a variety of slopes (for more information on the implications of this read the information in the full report after the pictures).
