Snow Squall Warning

Issued at 14:38 Wednesday 03 March 2021

Snow squalls are expected. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow combined with blowing snow, and snow will quickly accumulate.

Total snowfall: locally up to 15 cm in snow squalls.

Maximum wind gusts: southwesterly 60 to 80 km/h.


Burin Peninsula - south of Marystown.
Avalon southwest - near Point Lance.
Avalon southeast - between St. Joseph's and St. Shotts.
Southern Shore - between Witless Bay and Cape Broyle.

Time span: continuing this afternoon.

Remarks: The snow squall is expected to meander to the north through the afternoon. The squall may reach the metro area by this evening.


Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common.

Snow squall warnings are issued when bands of snow form that produce intense accumulating snow or near zero visibilities.
