A Flood Outlook - Watershed Conditions Statement has been issued and is in effect through to Tuesday August 11, 2015.



 Date:             Monday August 10, 2015

Time:              1:45PM

Issued to:     school boards, municipalities, local conservation authorities, local police, emergency services and media 

Weather Conditions:

Toronto and Region Conservation is advising that Environment Canada is forecasting  weather systems moving through the Greater Toronto Area this afternoon and evening. Each of these two systems is expected to bring 10-15 mm of rainfall through the Greater Toronto area, with thunderstorms in localized areas bringing up to 30-50mm of rainfall in a short time.


Forecasted rainfall amounts will result in higher than normal water levels and flows. Rivers and streams will be faster flowing, creating unsafe and/or dangerous conditions. There may be flooding on roadways and in low-lying areas.


The combination of slippery and unstable banks will create hazardous conditions close to any river, stream or other water bodies.


Please stay away from rivers and streams and exercise caution around all bodies of water. Please alert any children under your care of these dangers and supervise their activities.

This Flood Outlook Watershed Conditions Statement will be in effect through to Tuesday August 11, 2015. TRCA will continue to monitor streams and weather conditions closely. Further flood related messages will be issued as required.  For more information please contact the on-call Flood Duty Officer.
