Freezing drizzle advisory for Durham was issued late last night by Environment Canada.
Freezing drizzle advisories are issued when drizzle falling in sub-zero temperatures is expected to freeze on contact, and over time create icy surfaces.
The weather agency said surfaces such as highways, roads, walkways and parking lots may become icy and slippery.
“Freezing drizzle can produce thin, hard-to-detect layers of ice. Take extra care when walking or driving in affected areas,” it added.
