Siobhan Ryan presents the Met Éireann forecast on RTÉ
Met Éireann is forecasting a wet weekend of weather following lots of showers driven over Ireland by a 'vortex' in the Atlantic.
In her forecaster after the RTÉ news on Thursday, meteorologist Siobhan Ryan warned of very unsettled weather over the next few days.
"We've got a vortex steering in this very unstable westerly airflow," she said.
The forecaster said an 'organised band' of rain, that includes some 'nasty showers' would push in from the Atlantic on Thursday night leading to a wet start on Friday. It is expected to clear for a time but further rain will follow on with thunder included.
"Over the weekend it is looking extremely unsettled. Still a degree of uncertainty but it is likely to feed in some very heavy rain," she said.
She said rain is likely to affect all parts of the country on Saturday. She expects it to 'particularly heavy during' Saturday night. Between 10 and 40 mms of rain is expected.
Sunday will be brighter, drier and milder but showery also. MORE BELOW TWEET.
