Ground Conditions

Snow above: no snow
Route taken: Rhyd Ddu path
Next report: Friday 19-12-25
Conditions
No snow was seen during observations, but it was a little icy near the summit this morning. There was some frost and rime on vegetation near the summit and a thin, invisible but very slippery layer of verglas ice on some of the rocks on the path high up, the steps leading to the summit requiring great care.
A cloudy morning with a light breeze, and occasional sunny spells.
Essential equipment
Suitable seasonal walking equipment, including lighting (such as a headtorch or two each).
Carrying microspikes just in case could offer safer options when periods of freezing develop (see Additional Information below).
Additional Information
On the Tuesday of the report, the forecast suggests that the temperature on the summit will be just above freezing for most of the period until the next report on Friday, but that there will also be periods of freezing on Tuesday night and Thursday night. The temperature at the summit is forecast to be as low as -2ºC (feeling like it is as low as -11ºC at times).
A period of freezing is forecast for Tuesday night into Wednesday morning. Although it appears that any ice may disappear quickly as temperatures rise and rain begins, icy conditions may prevail overnight and early in the day, with the possibility of an extremely slippery period underfoot as the thaw begins, with rain falling on ice possible.
The forecasts suggest that it will cool down again on Thursday night, with possible freezing higher on the mountain on Thursday night into Friday morning. Some snow is also possible.
Between these freezing periods rain and strong winds are forecast, leading to hostile and cold conditions, even if there is no ice or snow.
