Mild temperatures and significant rainfall are expected to increase river and stream flows in the Grand River watershed this week and could cause local flooding, according to a media release issued by the Grand River Conservation Authority.
The increased flows will occur as a result of melting snow and rain running off frozen ground.
As temperatures increase, ice formed in the river is expected to move downstream, leading to a risk of ice jams and subsequent flooding.
Temperatures are forecasted to remain above freezing during the week and could reach 11 degrees Celsius on Wednesday. Cumulative rainfall could exceed 40 mm by Thursday morning, when the temperature is expected to drop below freezing.
The GRCA is warning of very slippery river and creek banks, which pose a serious hazard when combined with cold, fast-moving water.
Residents are encouraged to keep children and pets away from watercourses and off frozen water bodies until further notice.
