From Friday evening its looking to be very wet and windy along the West and south west Coasts. Winds will be southwesterly touching gale force at times, with gusts possibly up to 65mph ( storm force 10) at times , especially near coasts.
Rain amounts could lead to spot flooding in places , most at risk at this time would be low lying parts Galway, sligo , mayo and parts of Roscommon. Rain spreading to all areas later on.
As the storm moves more inland the winds will be dampened to an extent, but rain will still persist, heavy during Saturday morning in inland counties.
Below is Saturday's predictive run by MÉs 5 day chart.
And A Surface Pressure Chart For Friday
My guess for rainfall amounts at Mullingar to be 30-35mms of rain throughout friday night and saturday.
Seeing that im not so skilled at doing my own forecasts , all corrections and comments welcome .
