The Lake Simcoe Region Conservation Authority advises that 30-40mm of rainfall is forecast for today and through the weekend to early/mid next week. Higher amounts of rainfall may occur in localized areas as a result of thunderstorm activity.
This combined with recent rainfall is posing a risk of flooding along the Lake Simcoe shoreline.
Lake Simcoe Water Level
The water levels in Lake Simcoe are above average for this time of year, and are expected to increase in response to the precipitation and inflows from rivers and streams within the system. Currently the lake level is approximately 15 centimetres higher than average for this time of year.
The current wind forecast indicates southwest winds today in a range of 23 km/hr with the wind gusts up to 38 km/hr. The forecast for the next few days ranges from 14-25 km/hr winds with gusts of up to 38 km/hr.
There is the risk of flooding adjacent to the lake in low-lying areas due to impacts of wind action, rain and continued flows in the system.
Exercise extreme caution around all bodies of water. Please alert any children under your care to stay away from all watercourses and other bodies of water; and supervise their activities.
Residents, especially in the historically flood-prone areas, are advised to take necessary precautions to protect themselves, their pets and property.
This Shoreline Hazard Watch will be in effect through Tuesday, July 20, 2021, or until otherwise updated.
