Environment Canada is warning residents that a ‘wintry mix of precipitation’ is expected late Thursday afternoon, into the evening.
The agency issued a freezing rain warning for Sarnia-Lambton, along with London-Middlesex and other parts of southern Ontario.
“Precipitation may begin as rain or ice pellets in some areas before transitioning to freezing rain and ice pellets,” the weather alert noted. “Ice accretion may be limited during the onset as ground temperatures may be above zero.
“Freezing rain conditions may last through the evening and overnight hours in some areas before changing to freezing drizzle or light snow by early Friday morning.”
Surfaces such as highways, roads, walkways and parking lots may become icy and slippery, the agency added. Take extra care when walking or driving in affected areas.
