Special weather statement in effect for:
- Grand Falls-Windsor and vicinity
Major winter storm to impact much of Newfoundland later this week.
Meteorologists are monitoring a developing storm that will bring an extended period of winter weather for the ending of March. Persons planning weather-sensitive activities are advised to check for updated forecasts and should begin to consider alternate arrangements. Travel is expected to become difficult.
Precipitation: Light snow is forecast to spread across most of the Island on Thursday. Over southeastern Newfoundland, the snow will likely mix with or change to rain or freezing rain on Thursday night before transitioning to heavier snow on Friday. Precipitation is forecast to remain as snow over the remainder of the Island, with particularly heavy totals occurring over interior and northeastern sections. Lesser amounts appear likely for western and northern Newfoundland, where conditions are forecast to improve on Friday. Elsewhere, snow is expected to continue through Friday night and then taper off on Saturday.
Wind: Strong north to northeasterly winds will accompany this storm. Gusts over 100 km/h appear possible over the eastern half of the Island during the day on Friday and into Friday night. Winds are forecast to ease on Saturday.
Visibility: The combination of snow and strong winds will create considerable blowing snow, giving near zero visibility. The potential exists for blizzard conditions over some areas.
Ice pressure: Persistent onshore wind along the east and northeast coasts may result in extensive ice buildup or significant pressure, both along the coastline and in the bays, especially north of Cape St. Francis.
Wave action: Eastern facing shoreline areas of the Avalon Peninsula south of Cape St. Francis can expect pounding surf and high waves on Friday.
Synopsis: A low pressure system is forecast to develop off the east coast of the United States this evening, then track towards Newfoundland on Wednesday. As it approaches it will interact with a second, more intense low approaching from the south and the pair will deepen into a major winter storm southeast of Newfoundland on Thursday. There remains some uncertainty regarding the track of this system, and as result it is too soon provide precise numeric forecasts. Meteorologists will continue to monitor this storm and provided additional details as they become available.
