ST. JOHN'S, N.L. - Snowfall warnings have ended for eastern Newfoundland, but Environment Canada is warning of another wintry system headed to the area later this week.

Meteorologist Ryan Rozinskis says 18 centimetres of snow fell at the St. John's International Airport overnight Tuesday and into Wednesday -- Christmas Day.

Rozinskis says a low pressure system is expected to developed south of Cape Cod Thursday afternoon and intensify as it moves up the coast and passes near the Avalon Peninsula Friday evening.

He says the system could bring significant snowfall, strong winds and blowing snow.

The national weather forecaster says the same system could bring up to 15 centimetres of snow to parts of Nova Scotia overnight Thursday before it heads to Newfoundland.
