Hundreds of people have been warned to expect power cuts over the coming days amid the “significant thunderstorms”.

Heavy rain will start from tonight[/caption]
Today will start with a mixture of cloud and sunny spells before some patchy showers interrupt dry conditions.
From there showers will spread in to the south and west beginning to first turn heavy and thundery after nightfall.
It will come after a “humid” day with temperatures reaching 21C.
But looking to tonight Met Eireann warned: “Early tonight, showers will spread from the south, with a spell of more persistent and heavy rain developing in Leinster and Ulster later.
Scattered thunderstorms are possible with a chance of spot flooding.
A mild and humid night with temperatures not falling below 12C to 15C and mist and fog developing in a light southeast breeze.
But the thunderstorms will not stop tonight, and will instead continue over the coming days with meteorologists warning all areas will be affected.
Cathal Nolan, who runs social media account Ireland’s Weather Channel warned “large hail” and “frequent lightening” can also be expected.
And he confirmed fears of power cuts across the country.
He said: “All areas at risk but especially the east. What’s the cause of all of this thunderstorm activity?
“A shift in the jet stream will allow high pressure to build to our east while low pressure sits to our southwest before slowly pushing northwards through Wednesday, allowing for a very warm, humid but unstable airmass to become established.
“This plume of very warm air will allow for the rapid development of thunderstorms with favourable CAPE and strong shear, all combining to lead to the development of strong and locally significant thunderstorms with the potential for some disruption in or two locations.
“The associated risks as we head through the second half of the week include frequent lightning, large hail and gusty winds, localised power disruption, localised flooding concerns”
Tomorrow will start with thunderstorms across Leinster and Ulster amid some heavy rain.
Met Eireann have again warned of flooding in these areas.
However, the rest of the country will not escape the thundery downpours with “heavy showers and scattered thunderstorms” feeding up across the country.
DAYS ON END
And it’s another “humid” day tomorrow with temperatures of 16C to 21C.
Thunder will be accompanied by mist and fog tomorrow night as downpours continue in 14C temperatures.
There’s no end in sight to the raging thunderstorms as Friday and Saturday’s forecast are plagued by thundery downpours.
Met Eireann’s Aoife Kealy said: “Friday then it’s going to be another humid day with outbreaks of heavy rain and possible thunderstorms.
“And while Saturday is going to feel a little bit fresher it’s still going to bring some heavy showers and the chance of thunderstorms.”
Current indications are there could be a pick up in weather from next week with “lighter and patchier” rain falling.
This is expected to be accompanied by “dry and sunny spells”.
