Residents in Mississippi Mills, Ontario, are being told to prepare for a sudden weather shift as temperatures are expected to climb from extreme cold to double digits with rain this coming weekend. According to Environment Canada, Almonte and surrounding areas will see daytime highs of 8°C on March 6, 2026, and 10°C on March 7, 2026. This follows a “Yellow Warning” for extreme cold on March 2, 2026, where wind chills reached as low as -35°C.
The combination of melting snow and a 40 to 60 per cent chance of rain creates a higher risk for ice jams and localized flooding along the Mississippi River. While the Mississippi Valley Conservation Authority (MVCA) reported in January that watershed levels had returned to normal, the sudden thaw typically causes river flows and water levels to increase as runoff begins. Officials warn that rain falling on melting snow can weaken river ice and cause it to break up unexpectedly.
To protect local infrastructure during the spring thaw, the Municipality of Mississippi Mills started reduced load restrictions on municipal roads on March 2, 2026. These weight limits help prevent damage to pavement as the ground underneath softens. Public works crews and conservation officials are asking people with waterfront properties to watch river gauges and stay alert for changing water levels as conditions change over the weekend.
