Headline: There is a high probability that Storm Lorenzo will track close to or over Ireland later on Thursday and early Friday. There will be very high seas on Atlantic coasts and severe winds in some areas.
Thursday night: The centre of Storm Lorenzo will move east to southeastwards over Ireland on Thursday night with the strongest winds situated to the south of the storm centre. It will become very windy or stormy in Atlantic coastal counties overnight as winds veer westerly in direction. The swathe of strong winds will then transfer eastwards across the country during the night with the risk of inland gales across parts of Connacht and Munster. Squally bands of rain will accompany the strong winds with isolated thunderstorms possible, bringing a risk of spot flooding. Minimum temperatures of 10 to 14 degrees.
Friday: Strong winds and squally rain associated with Storm Lorenzo will clear during the course of Friday morning with some sunny spells developing in the afternoon. Highest temperatures of 15 to 18 degrees. It looks set to be dry at first on Friday night but outbreaks of rain will move in from the southwest later. Minimum temperatures of 9 to 12 degrees in moderate southeast winds.
