Gusts of up to 75 mph affected Northern Ireland during the night of the 21st & 22nd. Up to 100,000 houses lost power as tree branches fell on power lines. Fallen trees caused widespread disruption: in County Down, several people had to be rescued from their vehicles after trees had fallen on them; flooding was also reported at Rostrevor. Several roads across the province were blocked by fallen trees, including the M1 motorway and the main roads from Derry to Belfast and Coleraine. The Foyle Bridge in Derry was also closed for two hours early on the 22nd due to high winds.
