Warnings (In effect)

High water level warning in effect

Halifax Harbour and Approaches

Issued 09:54 AM ADT 22 September 2020 Higher than normal water levels are expected or occurring.

Maximum water levels: storm surge near 50 cm

Maximum wave heights: 7 to 9 metres, breaking higher along parts of the coast.

The high waves will persist into the overnight period. 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.

Coastal flooding is likely, especially during high tide. Marine interests close to the shoreline should stay alert for worsening conditions, especially during high tide.

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.
