The impacts are expected to be "highly localised".
Met Eireann confirmed most places will "become dry" tonight with patchy cloud and clear breaks, with just the odd shower possible, as temperatures drop to their lowest between 3C and 8C.
But parts of Ireland could be in for more thunderstorms tomorrow.
Met Eireann said: "Largely dry with variable cloud and sunshine to begin tomorrow, Tuesday, but showers will soon develop, some of them heavy with spot flooding and isolated thunderstorms possible.

Met Eireann said mainly dry and sunny weather will return around midweek - although it is expected to turn "mixed and changeable" from the Atlantic next weekend.
The forecasters said: "Mixed and changeable with spells of rain or showers but some brighter, sunnier spells too. Temperatures returning to near average in a southwest to west airflow."
OMEGA BLOCK
Ireland has been
And Met Eireann revealed that the welcomed conditions are due an "Omega Block".
The Omega Blocking high - named due to its shape resembling the Greek letter Ω - is set to last until the end of next week, according to Met Eireann.
The weather boffins explained that the Omega block forms when the jet stream is weak and meanders from to south.
This ends up with stationary high pressure sandwiched between two low pressure systems to the east-southeast and west-southwest of where the high pressure is located.
Met Eireann said the system can be a stable blocking pattern which lasts for "an extended period of time" and is quite common on the eastern edges of the North Atlantic and North Pacific.

Midges, dogs, spiders, and fog were all once used to predict weather
Dare we say it… people — especially farmers, gardeners, and those responsible for public water supplies — welcomed recent rain after the long, dry warm spell. Trees, plants and flowers look greener and healthier after a good dose of 'soft' rain seeping into the roots... far better than hydrating with treated water which contains chemicals such as fluoride and chlorine. Now, I hear people wondering aloud, with sighs of trepidation: 'Have we had our summer?". It's far too soon, however, to be thinking that way as most of the summer is still to come. Though reluctant to confidently make exact weather predictions for more than a week ahead, due to the 'chaotic nature of the atmosphere', Met Eireann gives seasonal forecasts. For June, July and August, the outlook is for above average temperatures, with average rainfall overall. Temperatures are likely to trend between 0.5 and 1.0°C above average generally for the three-month period, possibly better in the south and east. Summer cloudburst: folklore had it that a halo around the moon meant bad weather; a red sunset the opposite. A north wind in summer and fog rising in the hills were good portents; while a dog eating grass, a cat sitting with its back to the fire and soot falling from the chimney signalled rain. The rainfall forecast is less certain with the potential for both wetter and drier periods. There is a signal for wetter than average conditions in June, and drier than average in August, with July hard to call either way. Sea surface temperatures around coasts and over the Atlantic to the west and south are expected to be above average in the period, says Met Eireann. All of which brings us to age-old weather folklore which people, particularly farmers, once depended on. Problem with that, however, was that much of it amounted to very short-term, sometimes almost immediate, forecasts. In summers long ago, when midges were active on humid summer evenings, or ants began to appear in large numbers, our elders told us rain way was surely on the way. And it invariably was. An example of weather lore on dú How people attempted to foretell the weather from natural signs features in the Dúchas national schools folklore collection. For instance, a halo around the moon meant bad weather; a red sunset the opposite. A north wind in summer and fog rising in the hills were good portents; while a dog eating grass, a cat sitting with its back to the fire and soot falling from the chimney signalled rain. 'Another sign of rain is when spiders leave their cobwebs," noted Jeremiah McAuliffe, a pupil in Ballyhass National School, Mallow, County Cork. Nowadays, we rely on science. Monthly forecasts, which are improving in accuracy, can provide an insight into weather patterns in the month ahead: will it be colder than average, wetter than average? Such forecasts should not be used for specific planning purposes, but can forewarn the likelihood of severe weather, enabling planned action to protect life and property.

Is it safe to travel to Rhodes and Turkey? Earthquake expert shares advice for holidaymakers
TOURISTS in popular holiday destinations in Greece and Turkey were shaken by a 5.8 magnitude earthquake this morning. Advertisement 3 A 5.8 magnitude earthquake struck this morning Around 70 people were injured in Southwest Turkey and a 14-year-old girl is known to have died due to a panic attack in the resort town of Fethiye. 2025 has seen the Greek islands experience significant seismic activity - with multiple Turkey also shook in April when powerful With the summer season in full swing, is it safe to travel to the region? Advertisement Read more on Travel advice Dr Margarita Segou - a seismologist with the British Geological Survey and editor-in-chief of Geophysical Journal International - is an earthquake expert and Greek national. She said: "Greece and Turkey are two very high seismic-prone countries." The countries' locations on a fault line known as the Hellenic Trench mean that they have seen large magnitude earthquakes, such as the 2023 Turkey disaster which left 53,000 people dead. However, speaking of the more recent tremors, she said: "Those magnitudes are well within the standard for moderate earthquakes in this region." Advertisement Most read in News Travel Dr Segou explains that as today's quake occurred at a depth of more than 70km, it would be classed as a "deep earthquake", which is not necessarily more dangerous. "Since the earthquake is deep, we have less damage than usual, although it means that it is felt in a wider area. Huge 5.8 earthquake strikes Greece & Turkey leaving 1 dead & dozens injured as 'panicked locals jumped off buildings' "Also the probability of a large earthquake immediately after is only heightened for a few days." Advertisement It does not advise against travel to the area and references February's earthquakes in Santorini - something Dr Segou admitted had been "an alarming phenomenon". However, she does not believe that the today's quake warrants cause for concern for anyone planning to travel to Greece or Turkey. 3 Guests at a hotel in Rhodes began gathering outside following the earthquake Credit: Stefan Harradine "I would not say that we are now facing a situation of increased activity within 2025." Advertisement Dr Segou revealed the steps holidaymakers should take if they do find themselves experiencing the natural phenomenon. "Tourists and populations should always follow the guidance from the authorities regarding any emerging situations. "If you feel an earthquake, it is better to be outside of the building a few minutes after. But during the strong shaking, one should always take cover beneath a very strong, well-built table, for example." She added that buildings in the region are well-prepared for these natural events and reasonably safe even if a moderate earthquake hits. Advertisement "Greece has a very strict seismic code and it is always abided by in construction. "The earthquake resistance plan for buildings is something that has proven correct and protective to people many times in previous disasters." Travel company TUI issued the following statement to those holidaying in the affected area: "Please remain calm and follow any safety instructions provided by your accommodation or local officials." Advertisement EasyJet also confirmed that its customers had experienced minimal impact to their holidays. If you are considering cancelling your trip to Greece or Turkey, bear in mind that as the FCDO has not formally advised against travel there is no guarantee that you will be refunded. Flights to and from both Rhodes and Dalaman airports are operating as usual with no disruption having been caused by the earthquake. 3 The popular resort town of Fethiye was hit by the tremors Credit: Getty Advertisement
