The Road Safety Authority (RSA) is calling on road users to be cautious on the roads amid the expected storm-force winds.
It is advising drivers to "beware of objects being blown out onto the road. Expect the unexpected. Watch out for falling/fallen debris on the road and vehicles veering across the road."
It adds: "Control of a vehicle may be affected by strong cross winds. High sided vehicles, motorcyclists and cyclists are particularly vulnerable to strong winds."
