The first reports of snow will be made here.

Note: The histogram may be updated before the report. If the dark updated line reaches the top it is an indication that there was little or no continuous snow cover observed.

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 Carneddau and to Foel-fras and Drum on the eastern end 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 (>50% cover) and any patchy cover (<50%). The diagram is updated at least weekly, but usually on Monday and Thursday during the season.
