Dozens of local schools have been closed, with reports of impassable roads and traffic gridlocked as winter returned with a bang overnight.
Heavy snowfall and temperatures hovering around freezing has meant that despite repeat gritting overnight even main routes are treacherous this morning.
There was gridlock during the morning rush hour at the Foyle Bridge and surrounding areas after slippery conditions resulted in some vehicles sliding backwards and blocking the dual carriageway.
Some motorists have reported being stuck on the birdge for an hour.
