Met Éireann has updated its nationwide thunderstorm alert to Orange status, with a warning of “flooding during heavy downpours”.
The warning is in effect from 3 p.m. today until 9 a.m. tomorrow morning.
“Thunderstorm activity expected. Not all areas will be affected due to the sporadic nature of development. There will be localized heavy downpours and hail. Flooding where heavy downpours occur,” Met Éireann said.
The UK Met Office has issued a yellow status warning for counties Antrim, Armagh, Down, Fermanagh, Tyrone and Derry from 9am today until midnight tonight.
A separate orange thunderstorm warning has been issued for counties Carlow, Kilkenny, Wexford, Wicklow and all six counties in Munster from 9am until 4pm tomorrow morning.
Meanwhile, Leinster, Munster and counties Cavan, Monaghan, Galway and Roscommon are also on a yellow high temperature warning until 6am tomorrow.
Searing heat swept across the country yesterday, with the highest temperature of 30.7C recorded again in Oak Park in Co Carlow.
Recent high temperatures and lack of rain have put pressure on water supplies across the country. Irish Water has warned that action has been taken at 37 of its 750 water supplies across the country “to ensure taps keep flowing despite increased demand”.
In most cases there is still no impact on customers, but there are a small number of places where overnight restrictions are in place.
This includes parts of West Cork, Kerry and Galway. Meanwhile, night-time restrictions are also in place at Carrigart and Lough Morne water works in Co Donegal, affecting several urban areas.
In addition to the areas where active intervention is taking place, there are over 60 water supplies across the country which are closely monitored by Irish Water to ensure normal supplies are maintained through the remainder of the summer and into the autumn.
Tom Cuddy, Irish Water’s Head of Asset Operations, said: “We would like to thank the public for their support to date in saving water and remind everyone to continue to take some simple steps to reduce their consumption. By reducing our water use, for example by turning off the hose and avoiding high-pressure washing, we can all help avoid further restrictions and ensure there is enough water for homes and businesses, agriculture, fisheries and essential facilities while we the rest of the time run through summer and into fall.”
Meanwhile, the Department of Agriculture’s Orange Forest Fire Warning, which was issued in response to “weather patterns and expected risk levels,” also remains in effect through Tuesday noon.
Met Éireann said today will be another hot day, particularly in Munster and South Leinster, with temperatures generally between 24C and 30C.
It will be cooler in the northwest and some other coastal areas where coastal fog may linger and sea breezes will develop in some places.
A few isolated heavy showers or thunderstorms may develop throughout the day, gradually increasing and spreading through the late afternoon and evening.
The forecaster said the “most intense, slow-moving floods” will cause some spot flooding, intense lightning and a low chance of hail.
Isolated heavy showers and thunderstorms will last overnight and at times turn into longer periods of rain, with local downpours and isolated flooding possible. It will remain warm and humid, with temperatures falling to 11C to 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 intensify during the afternoon with an increased risk of flooding.
Further north it will be fresher but drier with only isolated showers and intermittent sunshine. Highest temperatures will again be closer to average, ranging between 14°C and 16°C in the north and northwest and between 17°C and 23°C elsewhere.
On Monday evening, showers in the south will gradually subside to leave a mostly dry night with clear spells and lows of 10C to 15C. It will remain warmest near the east coast.
The meteorologist said Tuesday will be cooler and cloudier with scattered light showers and highest temperatures of 15C to 19C, mildest in the south.
The showers will subside early Tuesday evening, leaving a dry night with a mix of clouds, clear spells and lows of 8C to 13C.
Wednesday will be a dry day with a mix of clouds and sunny intervals in the morning and widespread hazy sunshine developing in the afternoon. Met Éireann said the highest temperatures are expected to be between 15C and 20C, with the warmest conditions along the south coast.
There will be clear spells early Wednesday night but clouds will increase from the west with rain spreading to the Atlantic coastal areas towards morning. The lowest temperatures range from 8 °C to 14 °C, mildest in the west.
A band of rain, which can be heavy at times, will sweep across the country throughout the morning on Thursday, followed by scattered showers later in the afternoon. The rain will taper off, giving way to more widespread sunny spells in the west as the evening progresses. Highest temperatures of 16°C to 22°C are expected, warmest in Münster.
“While confidence is still quite low for next weekend, current indications are that it will be milder and calmer for a while,” Met Éireann said.
