Flood Forecasting and Warning
The TRCA's flood monitoring gauge network spans the GTA, continually monitoring in-stream water levels at TRCA dams and river stations. Real time stream flow, water level, and precipitation information is available online at: http://www.trcagauging.ca. While designed as a portal for Flood Duty Officers, limited access to the website and data is available to the general public.
Toronto and Region Conservation updates terminology for flood messages
Effective February 2012, TRCA will be using new terminology for flood and water safety messages. The new terminology is being adopted by TRCA, other Conservation Authorities across Ontario and the Ontario Ministry of Natural Resources (OMNR). These changes will ensure that messages are consistent and in line with severe weather terminology used by other agencies such as Environment Canada and the Weather Network.
The TRCA issues three levels of messages:
|WATER CONDITIONS STATEMENT:
a general notice of weather conditions that could pose a risk to personal safety or which have the potential to lead to flooding. There are two variations of these:
The new terms were developed by a committee of representatives of Conservation Authorities, Conservation Ontario, the Ministry of Natural Resources, Environment Canada and other agencies. Monitoring weather and flood conditions is a shared responsibility of Conservation Authorities, OMNR, and Environment Canada. The OMNR Surface Water Monitoring Centre in Peterborough monitors weather forecasts and water levels across the province, providing the information to Conservation Authorities. Other information is also available from Environment Canada. When flooding is possible or about to occur, TRCA issues flood messages to municipal emergency management officials and the media. Municipal officials then take action to warn local residents.
Flood messages are posted in the Flood Forecasting section of TRCA's website. For additional information please contact TRCA's 24 Hr Flood Line at 416-661-6514 or 416.661.6600 ext 5697 or visit us on Twitter.
