The Department of Foreign Affairs has said it has been contacted by a number of Irish citizens impacted by the wildfire in Rhodes.
The fire on the Greek island has forced thousands of tourists and island residents to shelter in schools and indoor stadiums after they were evacuated from coastal villages and resorts.
Thousands spent the night outdoors and tour operators Jet2,TUI and Correndon cancelled flights departing for the island, which is located in southeastern Greece and is popular with holidaymakers.
The fires have caused road closures and extensive damage to property, particularly in the centre of the island, the DFA said.
In a statement, it advised Irish citizens to be alert and stay away from the affected areas, and to move rapidly out of any areas affected.
"This is an evolving situation, and citizens should comply with evacuation orders and follow the instructions from the emergency services and local authorities," it said.
If citizens are in immediate danger, they are urged to call the Greek Emergency Services on 112. The department said people should turn mobile phones on to roaming, to receive alerts from local authorities.
Temporary shelters have been established by the authorities in Greece for tourists who have had to evacuate their hotels.
"If citizens are planning to travel to Rhodes, it is important prior to travel that they check with their travel operator or agency, or their hotel, to see if the area they plan to visit is impacted by the current wildfires and evacuations. There is likely to be travel disruption," the statement added.
The department said that anyone in need of consular assistance can call the Irish embassy on +30 2107232771 or the Honorary Consulate of Ireland in Rhodes on +30 2241075655.

Ryanair flights to and from Rhodes Airport are currently operating as normal and unaffected by the fires.
The airline said passengers departing from Rhodes should be advised that it will accept temporary travel documentation issued by Greek police.
Aer Lingus said it does not operate flights to Rhodes and added: "In terms of our Greek destinations as per our schedule our next flights will be Tuesday so we'll monitor and advise customers accordingly."
TUI confirmed that it has cancelled all outbound flights from Ireland up to and including Tuesday, 25 July and passengers will receive full refunds.
Those due to travel on Wednesday, 26 July can amend to another holiday or cancel free of charge.
It says its customers, including those from Ireland, currently in Rhodes will return on their intended flight home.
Meanwhile, the Irish Travel Agents Association (ITAA) is advising holidaymakers on the island of Rhodes to follow local advice.
Most Irish tourists are in the northern areas of Rhodes which are unaffected. The wildfires are in the southeast corner of the island, it said.
