Met Eireann have issued yet another weather warning as parts of the east and south are due to become enveloped in fog overnight.
The Irish meteorological service has placed a status yellow warning for all counties in Leinster and Munster saying that dense fog will lead to poor visibility.
The warning is in place from 1am tonight and is set to last well into Wednesday morning.
Status yellow warnings are not a threat to the general population, but can be dangerous on a localised scale.
A status yellow fog warning is given when dense fog over a wide area or pockets of freezing fog are expected.
Tonight will be mostly dry and cloudy with clearer spells further south. The night will be calm but foggy with temperatures of 5 to 10 degrees.
Tomorrow morning fog will slowly clear to leave a largely dry day with sunny spells, mostly in the southern counties. Highest temperatures of 14 to 17 degrees.
