North Grampian - Mountain weather forecast

Weather warnings

Warnings affecting North Grampian over the next 5 days

Confidence

Quite high for a wet night and some rain to start Thursday but lower for the timing of the gradual brightening later Thursday and how far it gets. Reasonable over the weekend, but falling low by Monday.

Weather hazards

Poor visibility High likelihood Hide detail

Poor visibility presents challenging route finding conditions. Visibility could be significantly less than 50 metres in all directions with few or no visual references, especially on featureless moors or plateaux. Distances become hard to judge and cliff or cornice edges can be difficult to recognise. These conditions require good navigational skills. There is a risk of white-out conditions when mist or fog is combined with extensive snow cover.

Heavy persistent rain Low likelihood Show detail

Prolonged exposure to heavy rain can result in drenched clothing and a risk of hypothermia if not wearing good quality waterproofs. Terrain may turn increasingly boggy underfoot, while mountain streams will rapidly rise into spate and may become impassable. There may also be a risk of flooding in valleys or glens. If there is snow cover, a heightened avalanche hazard is possible and avalanche reports should be consulted where available.

Forecast

Sunrise: 06:57

Moon phase: New

Weather

Cloudy with further rain at times, with some heavy bursts possible in the morning, turning lighter and more patchy in the afternoon. Some brighter weather will push into the south and west of the area towards evening but the northern Cairngorms will probably see little improvement before nightfall.

Chance of cloud-free mountain/hill tops at 800m

10% or less overnight and into the morning with cloud widely down to 450-600m, then increasing to 40% in the south and west from mid afternoon and 70% by evening, though a slower improvement over the northern Cairngorms.

Visibility

Even below the cloud, outbreaks of rain and mist will give moderate, occasionally poor visibility until later, then visibility will improve to generally good or very good in the drier brighter weather reaching at least the south and west of the area.

Met Office Aberdeen meteorologist's view

The lowest freezing levels in the late evening will be associated with drier clearer conditions.

Friday 22 September 2017

Sunrise: 06:59
Sunset: 19:15
Moon phase: New

Weather

A cold night with perhaps a touch of frost in some glens. Then a dry start to Friday with some early sunny intervals especially in the north. Cloud will soon thicken and lower onto the higher or more southern hills, also bringing some outbreaks of rain by the late morning. A few heavy bursts are possible for a time towards Ben Alder and Creag Meagaidh before it turns light and patchy during the evening. Some clear spells will then develop across the north but some low cloud will linger across southern hills.

Temperature

  • At 800m Plus 4 Celsius rising to Plus 8 Celsius during the day.
  • Glen Down to 0 Celsius in places overnight and early in the day gradually rising to Plus 12 during the day.
  • Freezing level 1300m overnight and early morning rising above the summits from mid morning

Visibility

Starting off very good, away from any glen mist, falling moderate in rain, also some cloud on hills causing very poor visibility at height.

Chance of cloud-free mountain/hill tops at 800m

90% in early hours and into the first party of the morning falling to 20% in south and 50% in north from late morning until early evening, rising 40% in south and 80% in north in the evening,

Maximum wind speed expected

Strengthening southerly winds, with gale force summit winds from late morning around 45mph gusts 55-60mph, easing a little in the evening.

Saturday 23 September 2017

Sunrise: 07:01
Sunset: 19:12
Moon phase: New

A dry start then becoming cloudy, perhaps with a little light rain from mid morning to mid afternoon mainly in the south. Also cloud lowering onto hills. An improvement from mid afternoon with any rain clearing and increasing cloud breaks. A much windier day on the mountains with storm force southerlies expected on the Cairngorm Plateau from late morning and severe gales on lower Munros. Freezing levels will be well above the tops.

Sunday 24 September 2017

Sunrise: 07:03
Sunset: 19:09
Moon phase: New

Cloud thickening again overnight to bring some light rain, and cloud back down on the hills but an improvement expected in the morning with some sunshine breaking through and just the odd shower in the west. Overnight severe gales subsiding by morning with a fresh to strong southerly expected on the summits during the day. Some uncertainties about the timing of the clearance of this cloud and rain. Freezing levels well above the tops.

Monday 25 September 2017

Sunrise: 07:05
Sunset: 19:07
Moon phase: Waxing crescent

Confidence is low but the most likely scenario is for a dry day with some bright or sunny spells and a fresh to strong southerly breeze on the tops. The alternative scenario is for the rainband to return from the southeast, so regular checking of the forecast is advised.

Includes the North and West Cairngorms National Park, Monadhliath, Ben Alder, Creag Meagaidh, Loch Ericht and Loch Rannoch.

The North Grampian region includes a large part of the Cairngorm National Park and the Balmoral Estate, the Scottish home of the Royal family since 1852. Five of the UK's six highest mountains lie inside Cairngorm National park, and there are 55 Munros (mountains over 3,000 ft). You will also find three of Scotland’s five ski centres including the Glenshee Ski Centre, the largest in the UK. The centre extends across four mountains, Glas Maol the largest at 1,068 metres and Carn Aosda the smallest at 917 metres, and includes 36 different ski runs.

Most people agree that Creag Meagaidh in Glen Spean is where the east highlands meet the west highlands. It is also this location which provides one of the area's most popular activities - ice climbing. This is thanks to its vast plateau from which five Munros (that seem almost made for climbing) stretch out. Seeing as plenty is on offer for visitors and it is crammed in a relatively small area, it should come as no surprise that the Creag Meagaidh area has been praised as offering all that is good about the Highlands in a single nature reserve.
