Mountain weather
South Grampian and Southeast Highlands Mountain weather forecast table
Confidence
High for occasionally heavy showers developing for Tuesday, lighter well scattered showers Wednesday, then for a series of weakening rainbands crossing from the west, but detail of worst of conditions gradually lowering through the outlook period.
This evening forecast
Scattered showers dwindling in the north by late evening but a few sharp outbreaks continuing in the south of the area. Light northwest winds. Freezing level above all summits.
Mountain weather hazards
Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.
Strong Sunlight
Harmful UV levels from sunlight increase with altitude giving a greater risk of sunburn and eye damage, even on some overcast days. On breezy days, the cooling effect of wind on exposed skin may disguise any feeling of sunburn until it is too late. If there is snow cover, glare increases the effect of UV rays especially on the eyes. It is advisable to wear sun block, protective clothing such as a long-sleeved top and hat and have good quality eye protection.
Poor Visibility
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.
Thunderstorms
Lightning is a significant mountain hazard which can result in serious injury or death. Mountain terrain often leaves one highly exposed to lightning strikes. Hail may give unpleasant conditions with torrential rain and localised flash flooding also possible, mainly in Summer months.
Mountain weather forecast
Showers for Tuesday, heavy at times with the risk of thunderstorms during the afternoon. Moderate westerly summit breezes. Freezing level above all summits.
