The Road Safety Authority is urging motorists to be extremely careful today as Storm Dennis arrives.
Yellow rain and wind warnings are in place throughout Ireland until tonight.
Met Éireann says thundery rain will cause flooding in places, and winds will reach 100 kilometres an hour.
The RSA's Brian Farrell says people should only drive if absolutely necessary.
Already this morning gusts of 117km/h have been registered in Belmullet.
