A second wind warning is in place for Dublin and Louth.

The snow and ice warning that was issued yesterday has also been updated.
The warning is in place for all of Connacht, Cavan, Monaghan, Donegal, Dublin, Louth and Wicklow and will see "icy in parts tonight with wintry outbreaks."
Met Éireann added: "Some snow accumulations possible before morning, mainly across the north and on higher ground elsewhere."
The warning is valid from 8pm this evening until 10am tomorrow.
Met Éireann said that nationally the unsettled weather is likely to continue with periods of heavy rain and very strong winds expected.
Tomorrow will see "scattered rain showers and sunny spells elsewhere" while by Thursday night, minimum temperatures will be between 0 and -3 degrees.
The weekend is likely to be a wet one, with the forecaster predicting rain in all areas on Friday morning.
It is expected to dry up for the afternoon before more rain emerges.
Met Éireann said that Saturday will see a "very wet and very windy start" in association with Storm Dennis.
"Rain in all areas during the morning, heaviest in the west, clearing to blustery showers during the afternoon."
They predict "strong and gusty southerly winds veering southwesterly with gales on coasts.
There will be "another band of heavy rain crosses the country on Saturday night with southwesterly winds remaining strong to gale force."
Sunday is also expected to be wet windy with showers turning "wintry over high ground."
