Weather Alerts
squall watch in effect
Conditions are favourable for the development of squalls with wind gusts possibly exceeding 35 knots, frequent lightning and poor to very poor visibility in torrential downpours. Numerous showers and thunderstorms are possible today for Lake Erie. The threat should diminish early this evening. ### Poor to very poor visibility may contribute to voyage delays and make marine navigation hazardous. Please continue to monitor alerts and forecasts issued by Environment Canada. For more information monitor Canadian Coast Guard radio or Weatheradio stations.
Mariners are advised to prepare for potential squalls. Vulnerable vessels are most at risk and should seek safe harbour if underway.
