A snow squall warning was ended for the London area.
Early Sunday morning Environment Canada upgraded a snow squall watch to a warning for London and Middlesex County. The agency had also issued a winter weather travel advisory Sunday afternoon for Elgin County and Oxford County.
"Persons in or near this area should be on the lookout for adverse weather conditions and take necessary safety precautions," the weather agency said.
Sudden near-zero visibility from blowing snow and bursts of heavy snow were expected as the snow squall moves in.
"Snow squalls cause weather conditions to vary considerably. Changes from clear skies to heavy snow within just a few kilometres are common," said Environment Canada. "Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow. If visibility is reduced while driving, turn on your lights and maintain a safe following distance."
Up to 15 cm of snow was expected throughout the day Sunday with wind gusts of up to 60 km/hr.
By 8:19 p.m. Sunday, the weather agency ended the weather advisory for Eastern Elgin County, St. Thomas and Alymer. The snow squall warning was ended for Strathroy, Komoka and Western Middlesex County.
