Residents of northeastern Ontario, including Sudbury and Sault Ste. Marie, should prepare for heavy rainfall on Tuesday, April 28, 2026. Environment Canada has issued a special weather statement warning of significant precipitation that could lead to localized flooding and hazardous driving conditions.
Expected Rainfall Amounts
The forecast indicates that the region could receive between 20 and 30 millimeters of rain throughout the day. The heaviest downpours are expected in the afternoon and evening hours, with rainfall rates potentially exceeding 5 millimeters per hour at times. This amount of rain in a short period may cause water pooling on roads and low-lying areas.
Affected Areas
The weather advisory covers a broad swath of northeastern Ontario, including the cities of Sudbury and Sault Ste. Marie, as well as surrounding communities such as Elliot Lake, North Bay, and Timmins. Residents in these areas are advised to monitor local conditions and avoid driving through flooded roadways.
Safety Precautions
Motorists should reduce speed and increase following distances on wet roads. Visibility may be reduced during heavy rain, so use headlights and maintain safe driving practices. Pedestrians are advised to avoid walking near storm drains and flooded areas. Homeowners should ensure that gutters and downspouts are clear to prevent water damage.
Seven-Day Outlook
After Tuesday's heavy rain, conditions are expected to improve gradually. Wednesday will see scattered showers with cooler temperatures, while Thursday and Friday bring a mix of sun and clouds. The weekend looks mostly dry with seasonal temperatures. However, residents should stay updated as forecasts can change.
This weather event is part of a larger system moving across the Great Lakes region. Environment Canada continues to monitor the situation and may upgrade the advisory to a rainfall warning if conditions warrant. Stay tuned to local weather updates for the latest information.
