Environment Canada has issued a freezing rain warning London and Middlesex County.

The forecaster says an area of freezing rain is spreading into the region this morning.

It is expected to persist for a few hours then may change briefly to snow before ending in the afternoon.

Surfaces such as highways, roads, walkways and parking lots may become icy and slippery.

Residents are advised to take extra care when walking or driving in affected areas. Be prepared to adjust your driving with changing road conditions.

Freezing rain warnings are issued when rain falling in sub-zero temperatures creates ice build-up and icy surfaces.
