Thousands of people remain without power tonight following the strong winds of Storm Ali, while Storm Bronagh brought heavy rain to many parts of the country.
ESB Networks said 12,000 homes, farms and businesses were still without power after Storm Ali.
The majority are in the Cavan and Monaghan areas, while the rest are in parts of Longford and Galway.
At one point yesterday, there were more than 180,000 customers without power.
Crews worked into the evening, but some customers will be without supply for a second night.
Met Éireann said Storm Bronagh was expected to bring "heavy and possibly thundery rain" across Ireland this evening and overnight.
It is expected to be at its peak in the early hours of the morning as it moves across the English midlands and southeast coast.
Winds could reach more than 100 km/h in the UK, meaning there is a danger of fallen trees and widespread damage in the worst affected areas.
Met Office forecaster Simon Partridge said it will be the first time this season that southeast England will be tested by strong winds.
"The first storm to reach an area each year usually has some fairly significant impacts because all the things you didn't realise were diseased or rusted or whatever, that's the first time you know about it - when the first winds arrive," he said.
The Met Office alert warns of the risk of roof tiles blowing off, trees and branches falling and flying debris generally.
The second named storm of the season comes just a day after two people were killed during Storm Ali.
The unsettled weather is set to continue with another weather system forecast to bring more wind and rain over the weekend.
Met Éireann said: "The weather remains changeable and disturbed for the coming weekend and there is potential for another storm to form late Saturday into Sunday.
"The track of the depression is uncertain at this stage and both Met Éireann and the UK Met Office are monitoring developments.
"Further updates and relevant warnings will be issued as appropriate."
