Local flooding possible in Mississauga and Brampton, officials advise avoiding waterways

Credit Valley Conservation says rain and melting snow could raise water levels near the Credit River starting Wednesday and has issued a flood outlook in effect until Friday; officials warn people to stay away from rivers, streams and other watercourses.

Credit Valley Conservation has issued a flood outlook for parts of Mississauga, Brampton and nearby communities along the Credit River. A strong low-pressure system is forecast to bring rain, freezing rain and several centimetres of snow beginning Tuesday into Wednesday. Warmer daytime temperatures and an existing snowpack are expected to cause snowmelt. The conservation authority says runoff could elevate river and creek flows and weaken river ice. Key points: - Forecasted precipitation includes 10–15 mm of rain and freezing rain, plus about 5–10 cm of snow. - Air temperatures are expected to be above 0 C with daytime highs near 5 C in Mississauga, and the watershed has a significant snowpack (reported as 45 to 90-plus mm snow-water equivalent). - CVC warns that runoff could raise water levels, that urban streams and ice-covered rivers may be dangerous, and that localized flooding is possible in flood-prone or low-lying areas. - The flood outlook, issued shortly after 10:30 a.m., is in effect until Friday or until further notice; CVC will closely monitor conditions and issue additional statements as needed, and municipalities and emergency services have been notified. Summary: The outlook reports a risk of localized flooding and elevated flows from a combination of forecast precipitation and snowmelt, while noting that significant flooding or a widespread ice breakup is not expected. CVC will continue to monitor weather and water levels and may issue further statements; next public updates are dependent on changing conditions.
