Dublin basked in some autumnal sunshine yesterday, but the outdoor-friendly weather is set to give way to wet and windy conditions.
While the remnants of Hurricane Epsilon is expected to largely miss the country, a Status Yellow rainfall alert was issued for Donegal and a gale warning remains in place for Atlantic coastal waters.
However, Met Éireann warned that a bank holiday weekend that brought spells of occasionally glorious sunshine to parts of the south and east will draw to a close with heavy showers and blustery winds.
Donegal is set to bear the brunt of the rainfall brought by the tropical storm, which is now all that is left of Hurricane Epsilon.
The main storm front is expected to track far to the north-west of Ireland as it moves between Iceland and Scandinavia, though it will bring heavy rainfall over northern Europe.
The showers over Donegal could see 40mm of rain falling overnight - with potentially even heavier rain on mountainous areas with a risk of spot flooding.
Gardaí have urged motorists to drive with care given the likelihood of very challenging road conditions over the next 24 hours - and to slow down, allow extra braking distance and never to drive into flood waters.
A gale warning is also in place for coastal waters as winds are expected to gust to Gale Force 8 into this morning with a small craft warning also being issued.
For the rest of Ireland, today will open with sunny spells and scattered showers - with some of the best sunshine in Dublin and along the east coast.
Temperatures will reach 12C.
A band of heavier rain will slowly extend across the country from the southwest this evening.
"Tomorrow rain will gradually clear eastwards in the morning and sunny spells will follow. Showers will develop in the west and south towards evening," a Met Éireann spokesperson said.
"Wednesday looks like being a bright day with sunshine and showers, these mainly over the western half of the country and highest temperatures of 9C to 11C.
"Thursday will be a mild, breezy and wet day with spells of rain in all areas."
Temperatures will remain mild and range from 10C to 12C, again being warmest in Dublin and along the eastern seaboard.
"Friday will continue to be mild with further spells of rain and highest temperatures of up to 16C.
"The current indications suggest that the weather will continue to be mild and unsettled over the weekend with spells of heavy rain or showers and with strong winds at times."
Daytime temperatures are expected to remain average for this time of the year though, over the next fortnight, the risk of ground frost will increase as overnight temperatures sink towards zero.
