Mountain weather
Mourne Mountains Mountain weather forecast table
Confidence
High for changeable conditions for rest of the week, windows of drier, brighter weather, but also spells of rain and stronger winds. Confidence remains low on day to day details.
This evening forecast
Cloudy with hill fog and rain moving northwards this evening, rain heavy at times. Fresh to strong southerly 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 cloudy day with outbreaks of rain and drizzle throughout.
