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 re-accommodate customers.
Dublin Zoo said it is "sorry for any disappointment caused", but added the decision was made "as the health and safety of our visitors and staff is a priority at all times."
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.
Met Éireann says southwest to west winds will reach mean speeds 55 to 65 km/h, gusting 90 to 110 km/h.
They will develop later this afternoon and evening and will continue overnight and through Wednesday.
A period of stronger winds are expected for a short time later today and this evening.
