Warnings (In effect)

High water level warning in effect


Issued 09:53 AM ADT 22 September 2020 Higher than normal water levels are expected or occurring.

Maximum water levels: storm surge near 50 cm except higher in areas where large waves break on shore.

Maximum wave heights: 7 to 9 metres, possibly exceeding 10 metres over eastern areas.

Locations: from Yarmouth County east to Sydney.

Time span: For Southwestern Shore: near high tides this morning and evening. For Eastern Shore and eastern Cape Breton: near the high tides this evening and on Wednesday.

Remarks: The main risk is for very large waves, rough and pounding surf, and a threat for rip currents. 2-3 metre waves at the coast this morning will build to 7-9 metres late in the day. The high waves will persist into the overnight period and into Wednesday over eastern areas. Outside of the times for high tide, there is still a threat for very large waves, rough and pounding surf, and local overwash. The public should observe extreme caution.

Vessels, infrastructure, and equipment are at risk of damage in areas directly exposed to high waves and pounding surf. Coastal erosion is likely in vulnerable areas. Exposed coastal areas are at risk of flooding, and vessels and marine infrastructure in those areas are at risk of damage. Mariners are advised to avoid affected shorelines.

High water level warnings are issued when water levels pose a threat to coastal regions.

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