Mountain weather
Mourne Mountains Mountain weather forecast table
Confidence
High for a generally settled spell of weather over the next few days. Low for any cloud and rain detail over the weekend.
This evening forecast
Largely cloudy this evening with outbreaks of rain at times but becoming drier by midnight. Fresh to strong southwesterly winds.
Mountain weather hazards
Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.
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
A largely cloudy and dry day. Light to moderate winds.
