Plunging temperatures could bring hail, sleet and snow across Donegal tonight.
Met Eireann has warned that heavy showers will move in as temperatures dip to -1 degree.
There will be an accumulation of snow on hills but snow could also fall on lower ground.
Many parts of the county were caught unawares on Monday to wake up to a blanket of snow.
Again drivers are asked to slow down and to take extra care with hail, sleet and snow likely to fall.
Donegal has had two weather warnings issued – for 3cm of snow tonight – and for winds touching 110km/hr.
