Forecast
Today will be wet and windy as Met Éireann forecasts outbreaks of rain progressing over much of the country.
The outbreaks will extend gradually northeastwards by the early afternoon and will be heaviest in the south and southeast leading to possible flooding in the area.
The rain will be accompanied by cold and strong winds coming from the south with temperatures reaching highs of 10 to 15 degrees.
Tonight will be mostly dry but will see some light and sparse rain. There will be a few showers coming in from the west and northwest overnight.
Fresh and gusty winds will continue with temperatures due to drop to 8 and 11 degrees. The winds will ease and become lighter overnight.
The forecaster has said that Monday will bring outbreaks and drizzle at first before bright conditions extend from the southwest through the afternoon.
Temperatures will reach 11 to 16 degrees with moderate winds.
Tuesday will be areas of cloud and patchy drizzle for part of the day but promises sunny spells as the day progresses.
Temperatures will reach 13 to 16 degrees accompanied by light to moderate winds.
Wednesday will be mostly dry with a mix of cloud and sunny spells while coastal counties will be affected by light showers.
Thursday will be dry in most parts but clouds will develop as the day goes on with some light drizzle due on the south and west.
Met Eireann has warned that some of the expected showers could be heavy.
The weather is due to be stable during the week but turns unsettled towards the end of the week.
The forecaster has said that the weather is “gradually turning more unsettled as low pressure edges in from the Atlantic”.
A spokesperson for Met Eireann has said that today “the heaviest rain will gradually move eastwards along the south of the country which is why the southern counties are mostly concerned by the Orange warning”.
They urged people to take into consideration the likelihood of flooding, travel disruption and poor conditions on roads.
They noted that most of the strong winds will dissipate by the half of Sunday night and that the coming week will see “some rain showers on Monday, a primarily dry Tuesday due to high pressure building”.
“There will be some showers but the weather will be predominantly dry while things become more unsettled next weekend,” they said.
The forecaster said that predictability for weather for conditions in Ireland was “very low” due to the country’s location.
“We get quite changeable conditions so it’s very hard to give anything definitive,” they said.
