Environment Canada has issued a special weather statement for the Avalon, Bonavista and Burin Peninsulas and Clarenville area for possible stormy weather, beginning Friday afternoon.
It says a low pressure system is forecast to form over the southeastern United States and track northeastward toward Newfoundland on Friday. This system will pass east of the Avalon Peninsula on Saturday.
"While it is too early to predict the snowfall amounts associated with this system, there exists the potential for significant snowfall, high winds, and blowing snow over southeastern Newfoundland beginning Friday afternoon."
Extreme cold warnings for Labrador coastal communities
Meanwhile, extreme cold warnings have been issued for parts of Labrador, including Hopedale, Nain and the Postville-Makkovik area.
Environment Canada says a frigid Arctic air mass will give extreme wind chills tonight and Thursday morning.
It cautions that while anyone who isn't dressed warmly is at risk in cold weather conditions, some are at greater risk than others for frost bite and hypothermia:
- homeless people;
- outdoor workers;
- people living in homes that are poorly insulated (with no heat or no power);
- people with certain medical conditions such as diabetes, peripheral neuropathy and diseases affecting the blood vessels, people taking certain medications including beta-blockers;
- winter sport enthusiasts;
- people who consume excess alcohol;
Extreme cold warnings are issued when very cold temperatures or wind chill creates an elevated risk to health such as frost bite and hypothermia.
