Floods forecast for south and east; UK braced for Hurricane Bertha
Met Eireann has issued a weather warning for parts of the east and south of the country, while the UK is bracing itself for high winds and flash floods as Hurricane Bertha moves in.
Up to 40 millimetres of rain is expected to fall overnight in Dublin, Carlow, Kildare, Kilkenny, Wexford, Wicklow, Cork and Waterford.
Met Eireann said: Thundery showers and sunny spells will continue this evening, with heavy rain gradually developing across Munster.
"The heavy rain will extend into Leinster and east Ulster early tonight."
Heavy and thundery downpours are forecast from 10pm up until 10am tomorrow morning, with localised flooding likely in some parts.
Met Éireann stated: "Rainfall totals of 25-40mm are expected in 12 hours."

Meanwhile, Britain is bracing itself for Hurricane Bertha.
The Red Cross has mobilised hundreds of volunteers who are on standby amid fears people will need to be evacuated from their homes.
The deluge was set to hit Cornwall this evening and quickly sweep across the rest of Britain. It follows torrential downpours on Friday which caused flooding across eastern England and saw more than 1,400 homes hit by power cuts.
Britons were warned to batten down the hatches as gale-force winds are predicted to tear along coastal areas, while 50mph gusts will batter the rest of the country.
Forecasters said the bad weather will plunge the country into autumnal conditions in the middle of summer.
Alister McHardy, from the Met Office, said much of Britain will be hit by up to two inches of rain overnight.
He said: “Anywhere in England and Wales could get two inches – even the far south east of England could get a good dollop of rain.
“We are going to see coastal gales in the south coast of England of around 50-60mph. Even inland there is a risk of gales in places. Generally the winds will be around 40-45mph. All places are going to see these strong winds - anywhere in England and Wales will see this.
“The rain is going to be heavy, but not torrential. But there is going to be a risk of surface flooding. It is definitely going to feel cooler and fresher, and the winds are going to be quite strong.
“Britons should brace themselves and be aware that the rainfall could bring some flooding in places.
“It is a quick dose of autumn in the summer.”
The Met Office has imposed yellow weather warnings telling people to “be aware” for rainfall for England, Wales and Scotland.
Hurricane Bertha has already torn through the Caribbean, with 90mph winds leaving thousands of homes without power.
Its aftermath, while not as potent, could still wreak havoc on parts of the UK.
Mr McHardy said: “Bertha has come across the Atlantic quite quickly. It is the remnants of that we are seeing over the next few days. Former hurricanes quite often hit Britain during the autumn, but for it to happen in August is quite unusual.”
Further bad weather is expected on Monday and Tuesday, as showers and 45mph winds are predicted to hit Britain.
Large swathes of the east of England have already taken a battering from heavy rain and flooding on Friday.
Norfolk, Cambridgeshire and Lincolnshire were the worst affected, with residents having to be evacuated from their homes and fire crews battling through the night to pump out the rising tide of water that had hit.
And marooned drivers taken by surprise at the rising water had to abandon their cars in flood-hit roads.
Head of UK emergency planning and response for the Red Cross, Simon Lewis, said: “We have hundreds of volunteers stationed across the UK and poised to help people who may be affected by possible flash flooding.
“Experience tells us that extreme weather could also lead to evacuations of homes and power cuts and we are ready to respond.
“We would urge people to keep a close eye on the forecast and think about preparing some basic emergency supplies in case the weather does take a turn for the worse.”
Environment Agency flood risk manager Craig Woolhouse warned that powerful winds could conjure up large waves which posed a flood risk to parts of the coast.
He said: “On Sunday and Monday a combination of high spring tides and strong westerly winds bring a risk of large waves and spray and possible flooding to the South West coast of England and along the Severn Estuary.
“If you’re travelling to or from holiday then check your flood risk before setting off and don’t drive through flood waters.”
