Gritters will be out in full force this morning with temperatures expected to plummet to-5C.
Aberdeen City Council had its gritting team undertake work from 4.45am to ensure primary roads are ready before rush hour.
Their move came after the Met Office confirmed that “widespread frost” is expected this morning, with icy surfaces becoming an additional hazard along with strong winds across the north-east.
Temperatures will drop to -5C before reaching a high of 5C for the rest of today and a high of 7C tomorrow.
People are being warned that frost will be “severe over any snow cover, and in sheltered glens”.
The frosty temperatures are expected to continue into Friday morning.
Rain, preceded by hill snow, is forecast on Friday with scattered showers in the south of the north-east.
A dry and windy start to Saturday will be followed by persistent rain and winds again, with wind speeds of up to 50mph.
A yellow weather warning has been put in place from noon on Sunday to noon on Monday.
Heavy rain is also predicted and, with already previous rainfall, there is a risk of further flooding over the weekend.
Storm Dennis is expected to bring a range of impacts, including delays and cancellations to transport services, damage to power supplies and large coastal waves.
Paul Gundersen, chief meteorologist at the Met Office said: “While these winds have the potential to bring impacts, they are not as strong as the gusts we saw last weekend with Storm Ciara, when a gust of 97mph was recorded on the Isle of Wight.”
