Storm warning for St. John's, Avalon Thursday


Environment Canada has issued a winter storm warning for Thursday for St. John's and the Avalon Peninsula, with possible snowfall amounts of 15 to 25 cm by Thursday night.

The red areas on the Environment Canada map are where warnings have been issued — a winter storm warning for the Avalon Peninsula Thursday and extreme cold warnings for the Northern Peninsula and parts of Labrador. The yellow area is where a winter storm watch has been issued for Thursday and the grey area is where a special weather statement has been issued for Friday.

Winter storm watches are also in effect for Clarenville, Bonavista and Burin areas.

Environment Canada says heavy snowfall with blowing snow is expected on the Avalon Thursday.

A low pressure system is expected to track across the Grand Banks late Thursday. Snow, at times heavy, will develop early Thursday morning and persist into Thursday night.

The snow may mix with ice pellets late in the day over eastern portions of the Avalon. Total snowfall and ice pellet accumulations by Thursday evening are forecast to range between 15 and 25 centimetres, although higher accumulations are possible. Additionally, northeasterly winds gusting to 80 to 100 km/h will combine with falling snow to reduce visibilities in blowing snow through the day Thursday and into Thursday night.

There's also a special weather statement for another winter storm that will affect Newfoundland Friday night.

Environment Canada says this storm is expected to develop off the United States east coast Thursday night and intensify as it approaches Newfoundland from the southwest Friday night.

While there remains uncertainty as to the exact track and intensity of this system, forecast guidance indicates that parts of central and western Newfoundland could see upwards of 15 centimetres of snow from Friday afternoon to Saturday morning, while parts of eastern Newfoundland could see wind gusts in excess of 100 km/h.

Saturday, Newfoundland should get a break from the stormy weather, but periods of snow are also forecast for Sunday and Monday. At this time, however, there are no details of how much.
