Kerry Airport has cancelled its 1pm flight from Dublin and its 1.20pm flight to Dublin this afternoon because of Storm Frank.
Strong winds, heavy rain and high tides are forecast to batter many parts of the country over the next 24 hours.
In terms of wind, Storm Frank will be at its most severe late this afternoon and this evening.
The areas most affected will be from Kerry and Cork up through Limerick, Clare, Galway, Mayo and into Donegal.
Kerry County Council is advising property owners, particularly in areas prone to flooding in the past, to take appropriate measures to minimise the risk of flooding to their properties.
Southerly winds associated with Storm Frank will reach mean speeds of 65 to 80km/hr with gusts of 100 to 120 km/hr, strongest in coastal areas this afternoon, evening and early tonight.
Under these conditions there may be a high risk of localised flooding, particularly in areas that have been prone to flooding in the past.
The rain warning is for 40 to 70 mm of rain to fall between midday today and midday tomorrow Wednesday.
The council is also advising that with high winds there is also a risk of damage or injury from falling trees and debris.
Kerry County Council Staff say they will be assessing the situation throughout the day.
