Monday, March 1st 2021, 7:50 pm - After marching through the Maritimes Monday, a vigorous winter storm will barrel through Newfoundland Tuesday with blizzard conditions and heavy snow.
March certainly started off like a lion in Atlantic Canada, with a powerful winter storm that delivered strong winds, heavy snow, and rain across the Maritimes, prompting widespread winter warnings throughout the region. The storm's impacts will be waning in Maritimes by Tuesday morning, but in behind it will be some frigid temperatures and wind chills, along with intense winds. During this time, the storm will be in full force in Newfoundland. Parts of the island could see 20-35 cm of snow, and coupled with howling winds, this will make for dangerous blizzard conditions. Wind gusts may hit as high as 140 km/h in the Wreckhouse region, which will make for treacherous travel in areas of heavy, blowing snow. More details and timing, below.
- Snow continues Tuesday with possible blizzard conditions, intense wind gusts
- 20-35 cm of snow in western, northern Newfoundland
- Temperatures take a nosedive in Maritimes, winds remain strong
