Weather Situation

Minimal precipitation is currently forecast over the Province Sunday June 16th to Thursday June 20th.

Sustained winds over the Great Lakes over the next 5 days are currently forecast to be less than 25 km/hr.

Risks

Levels and flows in the southern sections of northeastern Ontario continue to experience high, above flood critical conditions but are mostly stable or trending down. Levels and flows can be expected to remain high and watercourses will remain vulnerable as water continues to move through the system. Wind action on high water may also pose additional risk to shoreline properties in vulnerable areas around inland lakes and rivers systems across this region.

Given the above normal water levels on the Great Lakes, wind action and storm surge may pose additional risk at thresholds not normally considered a concern. Please see the flood messaging related to Great Lake water levels for additional details.

A close watch on local forecasts and conditions is recommended.


Flood Message Definitions

Provincial flood messages

There are 2 types of provincial flood messages:

  • the Provincial Flood Watch, which provides consistent and timely technical information about the potential for flooding
  • the Provincial Watershed Conditions Statement, which provides information on provincial watershed conditions as they relate to flood potential, and an outlook on expected spring flood conditions

Local flood messages

There are 3 types of local flood messages:

  • flood warning: flooding is imminent or already occurring
  • flood watch: there is the potential for flooding
  • watershed conditions statements: flood Outlook (an early notice of the potential for flooding based on heavy rain, snow melt etc.) and water safety information.

Who to contact for flood information

Your local Conservation Authority is responsible for local flood messaging.

Your local municipality is responsible for on-the-ground flood response.

If you live in a community that is not serviced by a conservation authority, any flood watches or flood warnings in your area are issued by the nearest Ministry of Natural Resources and Forestry district office.
