Levis sits in the St. Lawrence River valley in Quebec, where a humid continental climate produces cold, snowy winters and a spring melt season that is one of the region’s biggest annual flood risks.
Across the St. Lawrence from Quebec City, the city shares the same river-monitoring considerations as its larger neighbor. Ice jams during the spring thaw can cause the St. Lawrence and its tributaries to rise suddenly, and summer convective storms add a second flood risk later in the year, both of which Environment Canada tracks using its national radar network.
