An incoming autumn storm is set to drench eastern Quebec with up to 50 millimeters of rain and trigger wind gusts reaching 90 to 100 kilometers per hour between Sept-Îles and Gaspé, as well as across the Maritimes, starting Monday evening and lasting through Tuesday.
Two weather systems are combining to push heavy precipitation across the region, according to the available forecasts. The Côte-Nord region, specifically stretching from Sept-Îles to Natashquan, is expected to see the heaviest rainfall totals, ranging between 30 and 50 millimetres. This heavy downpour arrives in an area where Sept-Îles recorded only 2.4 millimetres of total precipitation since September 21, leaving dry soil primed to absorb the sudden influx. Meanwhile, the Gaspé Peninsula anticipates 20 to 40 millimetres of rain, and the Bas-Saint-Laurent area could collect 20 to 30 millimetres.
Rainfall Totals and Regional Impacts Across Eastern Quebec
The incoming weather pattern threatens multiple specific local sectors throughout the eastern part of the province. Environment Canada issued a special weather bulletin for a storm arriving Tuesday, October 6, warning that the Bas-Saint-Laurent and Gaspésie regions will face strong winds lasting roughly a dozen hours alongside rain. The affected zones include Rimouski-Neigette, La Mitis, the Matapédia Valley, La Matanie, Haute-Gaspésie, Grande-Vallée, the Gaspé National Park, Restigouche, Bonaventure, New Carlisle, Chandler, Forillon National Park, Gaspé, and Percé. Monday alone could bring up to 20 millimetres of rain to the area ahead of the main system.
Did You Know? Sept-Îles received a mere 2.4 millimetres of precipitation starting from September 21 before this storm system arrived to drench the dry soil with up to 50 millimetres of rain.
High Winds and Potential Local Disruptions on Tuesday
Winds will ramp up significantly on Monday evening before peaking on Tuesday in a strong wind corridor stretching between Sept-Îles and Gaspé, as well as parts of the Maritimes such as Prince Edward Island. Meteorologist Bissem Boujnane collaborated on the forecasts, highlighting that local gusts could hit 90 to 100 km/h. Environment Canada warns that the presence of autumn foliage could lead to broken tree branches and scattered power outages, while unsecured patio furniture, garbage cans, and Halloween decorations risk being blown away.
Gradual Return of Calm Weather by Wednesday
The heavy storm system is expected to lose its grip gradually as conditions improve across eastern Quebec. Forecasters indicate that the winds will subside progressively on Wednesday, allowing the region to dry out after days of heavy downpours and powerful gusts.
