Snowberry berries. Snow on the way?The first reports of snow in the new season will appear here.

Snowberry (left) has white berries well-developed so is it not time for some snow on the mountains? The small rather insignificant pink flowers in summer produce white round and fleshy berries in the autumn. They are particularly lush this year...

Pray for snow...

    Notes

    Observations are made as near to 0900 GMT as possible. I have a good view from Llansadwrn, weather permitting, across the Menai Strait towards the Snowdonia Mountains. I can see the northern slopes of the mountain range from Moel Eilio (west of Snowdon), Snowdon summits (Yr Wyddfa and Crib Goch), the Glyderau and Carneddau to Foel-fras and Drum to the east of the range near the Conwy Valley. With the aid of binoculars I make daily records that include any ice precipitation observed, the lowest altitude of snow lying at ( >= 50% cover), at ( >= 30% cover) and snow patches. I aim to update the diagram during the season at least twice weekly if there is any snow.
