Those heading up the highest peaks in the Lake District have been warned to expect serious winter conditions.
In its noon forecast today (December 6th), the Weatherline said "The fells are in full winter condition with a covering of snow and ice at all levels," with the drifts being typically 15 cm deep but often drifting to as much as 110 cm.
The forecast also noted paths are "treacherous" due to compacted snow and ice, while high mountains lakes such as Red Tarn are frozen over, but not thickly enough to walk on.
And narrow ridges like Striding Edge and Swirral Edge should only be attempted by experienced winter mountaineers.
Those venturing out may find they need not just walking boots
but also crampons, while winter jackets
may also help.Ordnance Survey maps
and a walking GPS
could help if the weather worsens and visual navigation becomes harder.
Striding Edge contains reminders of its dangers at any time, with a number of memorials on it to people who suffered fatal falls.
