Thunderstorms rolled in across the country this evening as a Status Orange thunderstorm alert remains in place for the entire country until tomorrow morning.

The warning from Met Éireann remains in place until 9am on Monday along with a Condition Orange Fire alert that will remain in place until midnight on Tuesday as tinder dry conditions pose a high fire risk – especially from dead grass, heather and gorse.

While the heatwave which began on Tuesday officially ended today, with Oak Park in Co Carlow the national hotspot, recording a daytime high of 29.4C, Met Éireann said the entire country is at risk of sporadic thunderstorms from this evening.

A Status Orange Thunderstorm warning will also remain in place for all of Munster as well as counties Carlow, Kilkenny, Wexford and Wicklow from 9am until 4pm tomorrow.

Met Éireann meteorologist Emer Flood said there were a number of very active thunderstorms moving across the country early this evening.

A particularly active one dumped 20mms of rain in just 15 minutes in Castlerea, Co Roscommon, earlier this evening, she said.

Other active thunderstorms with bands of lightning were also reported in counties Kerry, Cork and Limerick.

"They’re in most regions and there will be further ones popping up across the country overnight but they will be hit and miss,” she told Independent.ie

"They could be scattered anywhere overnight and into the early morning.”

A Status Yellow High Temperature Warning will also remain in place until 6am tomorrow for all of Leinster and Munster as well as counties Cavan, Monaghan, Galway, and Roscommon where overnight temperatures were not expected to dip below 15C following another hot day with temperatures in the high 20s.

Once the thunderstorms clear tomorrow morning, there will be a noticeable drop in temperatures and humidity.

Daytime highs will range from 14C to 16C in the north and northwest and between 17C and 23C elsewhere.

Yesterday saw scorching heat across the country, with the highest temperature of 30.7C once again recorded at Oak Park in Co Carlow.

The recent high temperatures and lack of rain have put pressure on water schemes nationwide. Irish Water has warned that measures have been taken at 37 of its 750 water supplies across the country “to ensure taps keep flowing” amid increased demand.

In most cases, there is still no impact on customers but there are a small number of locations where overnight restrictions are in place.

These include parts of West Cork, Kerry and Galway. Meanwhile, night time restrictions are also in place at the Carrigart and Lough Mourne water schemes in Co Donegal, with several townlands impacted as a result. 

In addition to areas where there are active interventions taking place there are over 60 supplies around the country that are being closely monitored by Irish Water to ensure that normal supply is maintained for the rest of the summer and into autumn.

Tom Cuddy, Irish Water’s head of asset operations, said, “We would like to thank the public for their support in conserving water to date and remind everyone to continue to take some simple steps to reduce their usage. By reducing our water use, for example turning off the hose and avoiding power washing, we can all help to avoid further restrictions and ensure there is enough water for homes and businesses, agriculture, fisheries and essential amenities as we go through the rest of the summer and into autumn."

Meanwhile, the Department of Agriculture’s Orange Forest Fire Warning, issued in response to “weather patterns and expected level of risk”, also remains in effect until noon on Tuesday.

Met Éireann said the thunderstorms will be  “intense slow-moving deluges” and will cause some spot flooding, intense lightning, and a slight chance of hail.

Scattered heavy showers and thunderstorms will continue overnight and at times merge into longer spells of rain, with local downpours and spot flooding possible. It will remain warm and humid with temperatures dropping to between 11C and 13C in Ulster and north Connacht, while staying above 14C to 17C elsewhere.

Met Éireann said scattered showers and thunderstorms will continue to affect the southern half of the country tomorrow. The rain will become intense throughout the afternoon with an enhanced risk of flooding.

It will be fresher, but drier further north with just isolated showers and intermittent sunny spells. Highest temperatures will return to closer to average, and range from 14C to 16C in the north and northwest to between 17C and 23C elsewhere. 

On Monday night, showers will gradually die out in the south to leave a mostly dry night with clear spells and lowest temperatures of 10C to 15C. It will remain warmest near the east coast.

The forecaster said Tuesday will be cooler and cloudier with scattered light showers and highest temperatures of 15C to 19C degrees, mildest in the south.

The showers will die out early on Tuesday evening, leaving a dry night with a mix of cloud, clear spells and lowest temperatures of 8C to 13C.

Wednesday will be a dry day with a mix of cloud and sunny spells in the morning and widespread hazy sunshine developing in the afternoon. Met Éireann said highest temperatures of 15C to 20C are expected, with the warmest conditions along the south coast.

Wednesday night will see clear spells early on, but cloud will increase from the west with rain spreading into Atlantic coastal counties towards morning. Lowest temperatures will range from 8C to 14C, mildest in the west.

On Thursday a band of rain, which may turn heavy at times, will cross the country through the morning, followed by scattered showers throughout the afternoon. The rain will clear and give way to more widespread sunny spells in the west through the evening. Highest temperatures of 16C to 22C are expected, warmest in Munster.

"While confidence is still quite low towards next weekend, current indications suggest it will turn milder and more settled for a time,” Met Éireann said.
