A predominantly dry day with sunny spells.
Rain will clear through the small hours of Monday morning and leave a legacy of broken cloud across the national park. The cloud will gradually lift and break up after dawn to give sunny spells through the morning. During the late morning and early afternoon there is a small chance of an isolated shower developing over the east of the national park. However, the shower risk soon passes and the afternoon will see long spells of sunshine across the region.

"The Llanberis path has snow from Clogwyn Station upwards. The path is difficult to follow with snowdrifts leading to the summit. The ability to navigate in winter conditions is essential. #beadventuresmart @visitwales @VisitWalesBiz #snowdon https://t.co/fsvNqQDMV3"
