Dublin Airport is experiencing flight cancellations on Monday, February 23, 2026, due to severe weather conditions on the east coast of the United States caused by Storm Hernando. The disruptions are impacting travel plans for passengers flying to and from Ireland.

Storm Hernando’s Impact in the US

Storm Hernando is causing widespread chaos across the eastern United States, leading to thousands of flight cancellations. The National Weather Service has issued warnings of heavy snow, strong winds and coastal flooding, potentially creating “impossible travel conditions and power outages”.

New York City Mayor Zohran Mamdani has declared a state of emergency and has ordered non-essential vehicles off city roads until noon today to facilitate snow removal and emergency operations. The city is under its first blizzard warning since 2017.

Potential Impact on Ireland

Whereas Storm Hernando is primarily impacting the US east coast, there is a possibility of a storm system affecting Ireland later this week. RSVPLive reports that weather models indicate a low system developing south of the country, potentially bringing rain and wind from Thursday into Friday. However, the extent of the impact on Ireland remains uncertain.

Passenger Advice

Dublin Airport continues to advise passengers to check with their airlines for the latest updates on flight schedules. Information is also available via the airport’s official X (formerly Twitter) account.
