Northumberland Strait

Issued 3:31 PM ADT 24 September 2016 Conditions are favourable for the development of waterspouts.

An outbreak of cold air combined with warm waters and favourable atmospheric conditions will give the potential for waterspout development this evening and on Sunday over gulf of magdalen and eastern northumberland strait waters.

Keep in mind that waterspouts cannot be seen at night and may strike suddenly. Waterspouts are generally isolated in nature although they can also occur in families of two or more. Waterspouts are generally short-lived in nature, typically lasting 20 minutes or less. Spray rings associated with waterspouts can measure in the tens of metres.

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