Donegal County Council is urging motorists to only undertake essential travel and to exercise extreme caution while driving. Schools in Donegal and six other counties will remain closed tomorrow because of the threat of the storm.
With a Status Orange Snow warning in place for the North West of Ireland, Donegal is set to be hit with heavy sleet and snow leading to blizzard-like conditions in parts with treacherous driving conditions from 3am to 3pm on Friday, February 18th.
A status Yellow Wind and Rain warning is also in place for the county, as the strong winds from Storm Eunice are accompanied by heavy rain and snow which will bring challenging conditions across Donegal during the expected storm period.
This is the second storm to hit the country this week and Met Éireann advises that Storm Eunice will track quickly over Ireland tonight and Friday morning.
Met Éireann has also issued a Red Wind Warning for county Cork and Kerry with Storm Eunice to bring severe and damaging winds.
Marine warnings are also in place for the entire Country with “cyclonic variable gale or strong gales, veering northwesterly overnight (Thursday) and on Friday on coasts from Erris Head to Malin Head to Belfast Lough.” Storm surge levels associated with Storm Eunice are predicted to significantly increase in a number of coastal areas.
A continued period of inclement weather is also forecast over the weekend and the public are asked to keep up-to-date with the current weather warnings and in particular any change in the status warning for their area.
