Confidence

Some uncertainty on Tuesday morning's rainfall detail given the slow moving nature of the frontal zone over Scotland. Otherwise high confidence in the broad themes for next 5 days.

Mountain hazards

Mountain weather hazards

Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.

Gales
Gale force winds (gusts over 50mph) make walking difficult and strenuous with a potential to be blown over by gusts. There is often a marked increase in winds through cols or on exposed ridges and summits. Distances can take longer to cover and compass bearings become harder to follow accurately.
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.

Mountain weather forecast

Cloudy with patchy rain. Turning heavy in the evening. Summit gales in the morning will moderate.

Additional weather information

Meteorologist's view

Note strong winds and summit gales early in the morning.

Weather

A frontal zone moves over the area bringing cloud and outbreaks of rain for much of daytime, but some drier spells are expected in the afternoon. Rain will then turn occasionally heavy in the evening and overnight. Gales on tops in the morning, moderating in the afternoon.

Chance of cloud-free hill tops

20%.

Low cloud and visibility

Fairly extensive cloud bases 500-700m through the day. Visibility below cloud bases will be generally good, deteriorating to a few kilometres in rain, especially in the evening.

Ground conditions

No recent ground conditions report available.
