This morning's snow seems to have caught the city's drivers - and the gritters - on the hop again.
The sudden flurries enveloped the city before the gritters got a chance to prepare the ground, leaving many hilly areas in Derry very hazardous.
One concerned pedestrian contacted the Derry News to issue a warning: "All over the town, cars are either crawling or forced to pull in. It's as if there's no traction on the roads at all."
