Drivers have been urged to take extra care on the roads following destruction caused by Storm Ali.
Meanwhile, electricity has been restored to around 90,000 properties as crews worked throughout Thursday to repair damage to the network.
The worst of the weather system may have passed, but officials say an ‘extensive’ number of roads across Northern Ireland remain closed.
A multi-agency lean-up operation is underway, but drivers have been advised to allow extra time for Thursday’s commute.
The Department for Infrastructure says its working to clear obstructions along with multi-agency partners and said road users should be aware of closures and diversions.
Meanwhile, around 9,000 people remain without power.
NIE say emergency teams have worked tirelessly to reduce the number of homes and businesses without power.
Customers who remain without power are widespread throughout Northern Ireland with some of the more significant areas affected in Portglenone, Magherafelt, Draperstown, Keady, Craigavon, Lurgan, Newtownbutler, Tamlaght, Waringstown and Mullaghbawn.
A spokesperson at NIE Networks, said,“We have mobilised additional call agents this morning to deal with any queries customers may have regarding the repair process in their area. If you are still without power this morning, then please do get in touch on 03457 643 643 or keep up to date online.”
Winds of up to 91mph hit Co Down - the highest ever recorded in Northern Ireland during the month of September.
The storm also brought travel disruption across the region, with over 60 roads closed, while thousands of homes were left without electricity following damage to power lines.
