A power outage is currently impacting 77 premises near Mountbellew and Moylough.
The ESB says it is currently working to repair the fault, which was reported just after 10AM.
It expects electricity to be restored to most homes, farms and businesses in the area by midday.
It's as a status orange wind warning is about to come into effect for Galway (11am) due to Storm Bram.
It's already in effect for counties in the south east, and the alert will extend to Galway, along with all other counties except Donegal, from 11AM until 7PM.
The orange warning then comes into effect for Donegal at 2 this afternoon, remaining in place there until 9PM
