Warnings

Warnings (In effect)

High water level warning in effect

Northumberland Strait

Issued 3:39 PM AST 26 November 2022 Higher than normal water levels are expected or occurring.

High winds, spring tides and some significant onshore waves will combine to give some flooding conditions and overwash this evening.

Maximum water levels: near flood level

Maximum wave heights: near 4 metres, breaking higher along the coast.

Locations: Northumberland Strait, especially east and south of Cape George.

Time span: during high tide 6:30 PM to 9:30 PM this evening.

Remarks: An extended period of intense north winds combined with spring tides and waves pushing south towards the coast will give some flooding and overwash. The highest threat is for north to northeast facing coastlines.

Coastal flooding is likely. Vessels, infrastructure, and equipment are at risk of damage in areas directly exposed to high waves and pounding surf. Coastal erosion is possible in vulnerable areas.

Please continue to monitor alerts and forecasts issued by Environment Canada. For more information monitor Canadian Coast Guard radio or Weatheradio stations.
