Report: a week on from sunshine and blue skies, the incoming storm may cause "significant" disruption

Professor John Sweeney from Maynooth University spoke to Gavin Jennings on RTE Radio 1's Morning Ireland about the impending arrival of Storm Hannah on Irish shores

"We've had a very unusual winer in that we've had the mildest winter on record and a very mild spring", explained Sweeney. "A lot of that was caused by a very stationary anticyclone over Europe, which is not uncommon at this time of year, but which fed in very warm air to us over the last two months. That has now faded away and we're back to Atlantic control on our climate and the resumption of a trail of depressions travelling across us."

Storm Hannah, which formed near Newfoundland before tracking across the Atlantic, will hit Ireland on Friday. "People should be very cognisant of the warnings coming from Met Eireann at the moment", said Sweeney. "It is a very deep depression and I think it will cause considerable disruption in the south of Ireland and the area of Munster and the north Kerry coast in particular."

With expected gusts of up to 130 km per hour, the storm has the "potential to cause a lot of disruption", explained Sweeney, "because trees have come into leaf and present significant obstacles"
