Motorists have been urged to re-think their journeys tonight as snow and ice make driving treacherous in some parts of Northern Ireland.
With significant snowfall settling in the north west, several accidents have already been reported and the PSNI and Traffic Watch NI have both issued travel advice warnings.
Multiple car accidents have occurred across Derry and Strabane in particular with one car careering down Creggan Road and hitting a gas metre.
