The Surface Water Monitoring Centre (SWMC) of the Ministry of Northern Development, Mines, Natural Resources & Forestry (NDMNRF) is forecasting increased water levels due to storm surge and wave heights.
Weather Situation:
A significant Colorado Low is forecast to move into the province over the next several days bringing high winds across the lower Great Lakes.
Risks:
The SWMC forecasted storm surge values for eastern Lake Ontario on April 14 and 15 might be high enough to cause localized shoreline erosion and inundation of low-lying areas.
Cataraqui Conservation is urging residents to take care along the shoreline.
