Localised flooding possible from overnight heavy rain and as a result some routes may remain difficult to navigate during the day. Still quite windy conditions through the day making for fairly arduous walking on exposed terrain with buffeting of clothing. Balance may be affected at times

A dry and bright morning before scattered showers feed up from the south through the afternoon into the evening, these heavy at times with a low risk of hail and lightning. Winds remaining gusty with summit gales at times.
Chance of cloud-free hill tops
50% around dawn rising to >80% by afternoon.
Low cloud and visibility
Some patches around 300-500m at dawn, mostly for southeastern upslopes around Slieve Binnian and Slieve Donard. Cloud above summits through the afternoon with good or excellent visibilities, but visibilities falling temporarily poor as heavy showers pass through.

No recent ground conditions report available.
