Met Eireann weather advisory issued for whole of Ireland as forecaster warns of brutal conditions

Met Eireann has issued a "weather advisory" for the entire country this weekend as a brutal washout is expected.

The alert is currently in effect and will remain so until 11pm on Friday, with forecasters warning of "further rainfall this weekend and next week will cause localised flooding due to waterlogged soils and high river levels".

The forecast for the rest of today, Friday, shows things remaining dry with isolated showers - mostly in Ulster. It will become a little cloudier with some bright spells, but cloud will thicken this evening and outbreaks of drizzle will develop in the southwest.

Tonight, rain in the southwest will extend across the country with some heavy falls in places - with spot flooding likely.

Temperatures will drop to around 5 degrees in some areas and will be coldest over the eastern half of the country before the rain arrives.

There will be a wet and cloudy start to Saturday, but the rain will clear eastwards in the early hours and will be followed by good sunny spells and scattered showers from the west.

As the evening approaches, these showers will become heavier in Atlantic counties with the chance of isolated thunderstorms. Saturday night will see a mix of cloud and clear spells with scattered showers continuing overnight, heaviest and most frequent over Atlantic coastal counties with the chance of spot flooding.
