Watches (In effect)

Waterspout watch in effect

Eastern Lake Erie

Issued 9:51 PM EDT 01 August 2021 The potential for waterspouts will continue this evening.

Mariners are urged to take all necessary precautions and prepare for the possibility of waterspout activity. Postpone voyage or seek safe harbour if possible. Waterspouts are generally short-lived in nature, typically lasting 20 minutes or less.

Waterspouts are generated by weak rotation under rapidly growing clouds or weak thunderstorms. Under favourable conditions, this weak rotation could intensify and become a tornado.

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