Latest: 19/04/2014 15:13 Helvellyn summit at 11:13 Saturday 19 April. The majority of the fells are now snow-free, although some isolated patches of snow still remain above 800m. These patches are avoidable, in sheltered hollows and on north through to east facing aspects. Helvellyn, with its large east face, retains the greatest coverage of snow. Striding Edge is now free of snow but Swirral Edge has a short stepped section of snow which is avoidable. The milder temperatures have weakened the cornices and snow slopes that exist above some east facing slopes so it's best to keep away from the snow along such edges. It was noticeably milder on the summit today, however conditions can change quickly and walkers should carry extra clothing and waterproofs. During this week the windchill has been as low as minus 6.5 degrees Celsius. Sun cream maybe also be useful due to strong sunshine. Temp plus 9.1 Deg C. Max Wind Speed 10.1 mph. Wind Chill plus 4.8 Deg C. Avg Wind Speed 2.3 mph SE. .
