Storm Eleanor is expected to bring strong winds and a risk of spot flooding as it 'moves quickly' across Ireland this evening.
An orange wind warning has been issued for Munster, Leinster and Galway until 10pm tonight.
Between 10pm tonight and 2pm tomorrow, a separate status orange wind warning will be in place for Galway, Mayo, Clare, Cork and Kerry.
Meanwhile, a yellow wind warning for the entire country until 9pm tomorrow.
Met Eireann says: "Storm Eleanor will move in off the Atlantic later this afternoon and will move very quickly across the country this evening.
"Southwest to west winds of mean speeds 65 to 80 km/h, gusting to 110 to 130 km/h, are expected.
"There will be very high seas along Atlantic coasts, with a risk of coastal flooding also.
"While a status yellow wind warning is in place for the rest of the country."
Deirdre Lowe of Met Éireann says it's a fast moving storm:

Dublin Zoo says the threat of Storm Eleanor has forced it to cancel its Wild Lights event for tonight.
People with tickets for later are being told they'll automatically get a refund in the next few days.
As the event is sold-out and ends this week, the zoo says it hasn't got room to reaccomodate customers.
