Dull and often drizzly conditions will dominate through the early part of Monday, with the most hazardous conditions on windward slopes. Although cloudy at lower levels, fells above 700m should stay clear after dawn due to an inversion layer. It will become dry across the park through the afternoon with cloud breaking to allow some late sunshine at all levels before dusk. Note that the ground may be saturated, and streams full and fast-flowing from previous days' rain, causing a loss of footing on steeper routes.
Moderate, but improving to good or perhaps very good visibility by the end of the afternoon.
Widespread broken hill fog below around 500m, this most notable on west-facing slopes but breaking to become quite patchy towards the end of the day.
Southwesterly 40-45mph, falling to 35mph by dawn, with the exception of areas above the cloud top, and backing to southerly during the afternoon. Southerly 45mph by evening.
|Valleys||Plus 11 Celsius falling to plus 6 Celsius overnight.|
|900 m||Plus 5 Celsius, falling to plus 1 Celsius overnight.|
|Freezing level||Well above the summits.|
Rather cloudy for much of the day, with some light rain at times. The widespread presence of hill fog, particularly over the south-facing fells, will cause difficulty in navigating around the park. Although it will be another very mild day, the combination of gale force winds and often persistent rain or drizzle will make it feel cool over the higher ground.
Very good, but poor in persistent rain or drizzle and hill fog.
Occasional broken or blanket fog above 500m.
Southerly 45-55mph with gusts of 65-70mph during the morning, particularly over the fell tops. Temporarily easing to 35mph during the afternoon.
|Valleys||Plus 6 Celsius, rising to 11 Celsius.|
|900 m||Plus 3 Celsius.|
|Freezing level||Well above the summits.|
A more settled day, with southerly winds easing to moderate by lunchtime. Although generally dry, it will be murky at first, with widespread hill fog at most levels. Although staying cloudy at some levels, conditions will improve with bright or sunny spells developing and the highest fell tops are likely to be clear of cloud. Freezing level above the summits.
Dry and bright with sunny spells and a moderate breeze at first. It will turn a little cloudy later and southerly winds will strengthen significantly as the day goes on. Freezing level still above the summits.
Dry and mild once again, but overcast with hill fog down to low levels. Southerly winds will reach gale force across the park and the freezing level will remain well above the summits.
