Residents in Lethbridge, Alberta, should prepare for a major weather shift as temperatures are expected to jump nearly 30 degrees in just a few days. According to Environment Canada, the city will go from a high of -10°C on Saturday, March 14, 2026, to a spring-like 19°C by Tuesday, March 17, 2026. This sudden warmth will cause existing snow to melt quickly, leading to slushy roads and standing water across the community.
The forecasted high of 19°C on Tuesday is much warmer than the typical mid-March high of 6°C for the area. The City of Lethbridge warned that rapid melting can overwhelm storm drains and cause water to pool on streets. Residents might notice mud and deep slush as the snowpack disappears during the warming trend.
To prevent water damage, homeowners are encouraged to clear snow away from their house foundations and ensure downspouts are working properly. Lethbridge County also suggests checking that culverts and ditches are clear to help move water away from properties. This proactive maintenance helps avoid issues with overland flooding in both urban and rural areas.
