- No high risks
- Persistent extensive hill fog
- Low confidence, however early low level mist lifting, more persistent base around 600m later.
- Severe chill effect
- Brisk southwesterly winds at height will make already low temperatures feel still colder.
- Heavy snow
- Storm force winds
- Heavy persistent rain
- Strong sunlight
Clear spells overnight are likely to lead to a frost and some low level mist at first this morning, mainly in the east where it will perhaps be locally freezing fog. This should lift through the morning, perhaps giving some limited sunny intervals for a time, however a more persistent cloud base around 600 metres should then see out the day. Becoming breezy at height through the day, leading to windchill, which will be exacerbated when taken with the chance of intermittent light rain that should see out the day.

Locally poor to start, improving good through the morning.
Relatively low confidence, some early low-level mist may lift to give hill fog around 300m for a time, with a more persistent base likely around 600m later.

This report is completed on a regular basis through the winter months by Snowdonia National Park Wardens and gives indicative information on snow/ice conditions underfoot in the Snowdonia area as a whole. Remember mountains can be inhospitable and dangerous places for the ill-prepared so it is important to check the forecast before setting out.

Brighter than on Tuesday, with a cloud layer around 600 metres readily breaking. Despite sunny spells, it will remain cold, with windchill significant in the near gale force wind at height. It should stay dry throughout.
Good or very good.
Well-broken around 600 metres.
Max wind above 500m
Southwest, later southeasterly 40mph.
- Minus 2 becoming plus 5 Celsius.
- Plus 1 becoming 3 Celsius, but note sub-zero layer developing below this.
- Freezing level:
- Sub zero layer gradually descending, from near summits to between 300 and 700m later.
Similar conditions to Wednesday: dry and bright with some sunshine, but with a strong southeasterly wind at height that is likely to consistently exceed gale force, leading to a considerable wind chill. A sub-zero layer between around 300 and 700 metres should warm out later.
While the wind should ease on Friday, cloud-cover is likely to become more extensive, perhaps resulting in a little rain at times. Strong southeasterly winds should ease southwesterly later, while the freezing level should remain clear of the summits.
Rather cloudy conditions are likely on Saturday, with some low level mistiness likely as the wind potentially falls light. There is a chance that the high peaks may just stand clear of this later, although confidence at this range is low. The freezing level should approach the summits.
