About Flood Messages

The Ausable Bayfield Conservation Authority (ABCA), has updated the terms it uses in flood and water safety messages effective February 2012. The new terminology is being adopted by the ABCA, other Conservation Authorities across Ontario and the Ontario Ministry of Natural Resources and Forestry (OMNRF). These changes will ensure their messages are consistent and in line with severe weather terminology used by other agencies such as Environment and Climate Change Canada and the Weather Network.

The ABCA issues four levels of messages:

  1. Normal – No flood conditions currently exist
  2. Watershed Conditions Statement - Flood Outlook / Water Safety
    General watershed conditions are being assessed for high runoff potential that could lead to flooding, and to remind the public of general river safety issues.
    Shoreline Conditions Statement
    Weather forecasts over Lake Huron suggest a potential for high waves reaching the shoreline and resulting in potential coastal flooding and erosion issues.
  3. Flood Watch:
    Flooding is possible in specific watercourses or municipalities. Municipalities, emergency services and individual landowners in flood-prone areas should prepare.
  4. Flood Warning:
    Flooding is imminent or already occurring in specific watercourses or municipalities. Municipalities and individuals should take action to deal with flood conditions. This may include road closures and evacuations.

The new terms were developed by a committee of representatives of conservation authorities, Conservation Ontario, the Ontario Ministry of Natural Resources and Forestry (OMNRF), Environment and Climate Change Canada, and other agencies.

When flooding is possible or about to occur, the ABCA issues flood messages to municipal emergency management officials and the media. The municipal officials then take action to warn local residents.
