The Road Safety Authority has advised all road users to exercise extreme caution and to "expect the unexpected" amid the blustery conditions.
Motorists are reminded that control of their vehicle may be affected by strong cross winds, with high-sided vehicles and motorcyclists particularly vulnerable, and they should be watchful of debris being blown onto the road.
Dipped headlights should be used at all times, and cyclists are urged to be wary of strong gusts which could blow them into the path of oncoming traffic.
