Met Éireann has renewed a status yellow fog warning covering 12 counties, with reduced visibility expected across parts of Connacht, northern Leinster and Ulster. The warning is in effect on Sunday night and may create difficult conditions for motorists and other travellers.
Breaking News: Yellow fog warning issued across 12 counties
The latest Ireland weather alert applies to Donegal, Cavan, Monaghan, Louth, Meath, Westmeath and Longford, along with all five counties in Connacht: Galway, Leitrim, Mayo, Roscommon and Sligo.
Met Éireann’s yellow-level warning highlights the potential for fog to develop widely across the affected areas. Drivers should expect visibility to change quickly, particularly on rural roads, at junctions and near low-lying ground.
What the warning means for travel
Dense fog can make it harder to judge distances, identify hazards and see other road users. Even where roads remain open, journeys may take longer and conditions can vary significantly over short distances.
People travelling during the warning period should allow extra time and adjust their speed to the conditions rather than relying only on posted limits. The following steps may help:
- Use dipped headlights when visibility is poor.
- Increase the distance between your vehicle and the one ahead.
- Reduce speed gradually and avoid sudden braking.
- Keep windows and mirrors clear of condensation.
- Check travel information before setting out.
Pedestrians and cyclists should also take additional care, as they may be difficult for drivers to see in thick fog. High-visibility clothing and lights can improve visibility, but road users should remain cautious even when using them.

Counties included in the Met Éireann alert
The warning covers the following 12 counties:
- Ulster: Donegal, Cavan and Monaghan
- Northern Leinster: Louth, Meath, Westmeath and Longford
- Connacht: Galway, Leitrim, Mayo, Roscommon and Sligo
The alert is significant for communities travelling between counties, because fog may not be confined to one town or road network. Conditions can also improve in one location while remaining hazardous nearby.
Why fog creates a road safety risk
Fog reduces the amount of time available to respond to hazards. Headlights from approaching traffic can also cause glare, making it more difficult to see clearly. On motorways and national routes, sudden changes in visibility can be especially challenging for drivers travelling at higher speeds.
Motorists should avoid using full beams in fog, as the light can reflect off water droplets and further reduce visibility. Dipped headlights and fog lights, where appropriate, are safer options. Fog lights should be switched off when visibility improves so they do not distract other road users.
What happens next?
Weather warnings can be updated, extended or cancelled by Met Éireann as new forecasts and observations become available. Anyone planning a journey should check the latest official forecast shortly before departure, particularly if travelling through Connacht, northern Leinster or Ulster.
The warning does not mean every location will experience the same conditions. However, the possibility of locally dense fog means travellers should prepare for delays and remain alert throughout their journey.
