Leitrim County Council has dealt with fallen trees on several roads in the north of the county.
A status orange warning remains in place for seven counties - Donegal, Leitrim, Sligo, Galway, Mayo, Clare and Kerry - until 8pm.
It’s reported there were gusts of over 135 km/h recorded off Belmullet in Co Mayo, and while wind speeds appear to have peaked on the west coast, they continue to pick up inland.
Council crews across the affected areas have teams in place.
