Mississauga residents are being urged to stay alert today as a weather system moving through southern Ontario brings the risk of heavy rain, thunderstorms and possible watershed flooding to the city.
The system is expected to deliver additional rainfall and thunderstorms this afternoon and evening, according to a City of Mississauga news release.
The Toronto and Region Conservation Authority (TRCA) and Credit Valley Conservation (CVC) are both advising residents to prepare for rapidly changing conditions, as soils are already saturated and water levels are elevated across local watersheds.
With soils already saturated and water levels elevated, rivers, streams and stormwater systems may respond quickly to additional rainfall.
TRCA warns that river and stream levels are already high and are expected to keep rising over the next 24 hours. Watercourses have not yet reached their peak, and stronger, faster flows are expected through the day and into tomorrow.
What the heavy rain could bring
According to the City, heavy rainfall in a short period of time can trigger hazardous conditions, and flood messages issued by conservation authorities are meant to help residents understand changing conditions and take appropriate action. If a flood warning is issued, residents should act immediately to protect themselves and their homes from flood damage.
Motorists, cyclists and pedestrians are being asked to use extra caution. Wet and windy conditions can make surfaces slippery and reduce visibility, the City said.
City crews on standby
The City of Mississauga is monitoring weather conditions and local waterways. Crews will monitor and maintain storm drains on city roads and respond to reports of water ponding or flooding.
Residents can report storm drain issues online or by calling 311, or 905-615-4311 from outside city limits. The City's Office of Emergency Management is continuing to track conditions alongside conservation authority and weather partners.
The City is encouraging residents to take small steps to reduce flooding risks and improve safety during the severe weather, and to stay informed since conditions can change quickly. Questions or concerns about flooding can be directed to 311.
