Environment Canada has issued a snowfall warning for the Avalon Peninsula, including the St. John's-metro region and the Burin Peninsula, with 10 to 20 cm expected tonight and into Christmas Day, and up to 25 cm on southern parts of the Avalon.

The weather office says a low pressure system developing near Cape Hatteras is forecast to track northeastward and intensify as it crosses the Grand Banks on Christmas day.

A mixture of flurries and freezing drizzle is anticipated across Southeastern Newfoundland today, well in advance of the approaching system. Snow associated with the low is forecast to reach the Burin and Southern Avalon peninsulas around midnight tonight and then spread across the Northern Avalon overnight.

Environment Canada says the snow will likely be heavy at times, with the highest accumulations occurring over southern parts of the Avalon where up to 25 centimetres may fall by the time the snow tapers off around noon on Christmas day. Elsewhere on the Avalon and Burin peninsulas, total snowfall amounts between 10 and 20 centimetres are anticipated.

Winds are expected to strengthen from a northeasterly direction ahead of the low with gusts reaching 60 or 70 km/h on Christmas morning. The wind gusts, fresh snow and relatively cold temperatures are expected to generate blowing and drifting snow resulting in poor visibility. Winds will shift to a northwesterly direction as the low moves away in the afternoon.

As this system is still in its early stages of development, Environment Canada says there is some uncertainty regarding its exact track and intensity. It will continue to monitor the storm throughout the day and says it may need to adjust forecasts as more information becomes available.
