One of them – as predicted in this picture – has caused a stir among surfers across Europe as it is set to bring an enormous swell to the Donegal coastline.
Surfers from across the continent have been making arrangements to head here to the North West in time for the swell on New Year’s Eve of New Year’s Day.
That will follow a potentially strong storm on Wednesday, say forecasters.
The severe wind event on Wednesday could bring an Orange Weather Alert from Met Eireann.
St Stephen’s Day will start wet but a clearance will slowly develop through the afternoon with Donegal dry by early evening. Highest temperatures of 4 to 7 degrees in the north.
The weather will stay changeable and unsettled. It will be cold on Saturday night with a widespread frost and icy roads, some patches of fog are likely also. Lowest temperatures plus 2 to -1 C.
Sunday will have cold frosty start, but the frost and fog should clear gradually, with some hazy sunshine at times, best over Donegal. Temperatures in the county of around 4C to 7C.
Fresh to strong southerly winds developing on Sunday night followed on Monday with windy and wet weather, with some heavy rain in places. But drier, clearer weather, will spread from the Atlantic later in the day and the evening. Highs of 9 to 11 C., in the morning, but values will fall during the afternoon. Cold early Monday night, with some frost, but mild, damp weather will push in off the Atlantic later.
Tuesday & Wednesday: It looks as if it will be a very windy, with strong to gale force and gusty southerly winds. Further rain at times too, much of it heavy.
