FLOOD WARNING: Saint Lawrence River – Update #7 

July 19, 2019

Weather Forecast:
There is a risk of severe thunderstorms and strong winds on Saturday, July 20, 2019.

Environmental Conditions:
Lake Ontario’s water levels rose slightly following this week’s severe thunderstorms. Water levels have since stabilized and will continue declining but will remain near seasonal highs for the next several weeks as record inflows from Lake Erie are expected to continue.

Flooding and other high-water impacts continue to be reported around the upper Saint Lawrence River during periods of active weather.

Risks:
The latest forecast from the International Lake Ontario – St. Lawrence River Board suggests that Lake Ontario’s water levels will continue to gradually decline throughout the summer, with the rate of decline largely depending on rainfall.

Lake Ontario’s increased outflows may increase Saint Lawrence River levels upstream of Iroquois throughout Edwardsburg/Cardinal and Augusta Township.

Residents are advised that wind may cause large waves, further aggravating water levels which may affect structures close to shore.

ACTION:

Residents in flood-prone areas are encouraged to closely monitor conditions and take necessary actions.

Residents are advised to stay away from watercourses where flows are high and where banks might be unstable. Parents are encouraged to explain dangers to children.

Residents in flood prone or low-lying areas historically susceptible to flooding are encouraged to closely follow evolving conditions and take necessary precautions to protect their property.

Duration:
This Flood Warning statement is in effect until Friday, August 2, 2019 at 5:00 PM.

SNC monitors the water levels and weather forecasts as part of the Flood Forecasting and Warning Program. Updates are provided as conditions change.

The International Lake Ontario – St. Lawrence River Board continues to monitor conditions on an ongoing basis. Information on hydrologic conditions, water levels and outflows, including graphics and photos, are available on the Board’s website at www.ijc.org/en/loslrb.
