Many roads around the county are impassable after heavy overnight rain.
Castlefin and Clady bridges remain closed as is Tinney’s Road, near Convoy, as well as a number of other routes.
Meanwhile, Donegal is set to be hit with gale force west to northwest winds with severe and damaging gusts from 7pm tonight until 7am tomorrow.
The winds, associated with Storm Franklin, accompanied by persistent heavy rain will bring challenging conditions across Donegal.
