40 cm of snow possible: A weather bomb is headed for the Quebec region

A serious coastal disturbance in its view east of Quebec. This system has all the ingredients of a weather bomb up its sleeve.

Good to know: The term weather bomb is used when a depression suddenly drops in pressure. Magic numbers: 24 millibars and more drops in 24 hours or less.

Eastern Quebec again

Between Sunday and Monday, the eastern part of the province will experience tremors. Rain is expected to begin Sunday morning and continue through Monday.

The Gaspé Peninsula will be the first to be affected. Accumulations will be heavy: up to 40 cm of snow, especially near the St Lawrence River. The surroundings of Saint-Anne-des-Monts can be particularly spoiled.

The north bank will be the next target. Between 10 and 20 cm of snow could fall there by Monday. 25 cm in some places on the Lower North Shore.

Winds will gust up to 90 km/h, reducing visibility on roads. Therefore, these areas still need a warning from Sunday evening to Monday morning. Route 132 will be closely monitored.

The gap widens

Ground snow accumulations are exceptionally high in eastern Quebec. The city of Sept-Eils won the prize for nearly 27 cm of snow. The contrast with southern Quebec is striking: 6-7 cm of snow covers the ground in this part of the territory.
