Watches (In effect)

Waterspout watch in effect

Haro Strait

Issued 01:46 AM PDT 23 March 2018 Conditions are favourable for the development of waterspouts.

A cool and very unstable airmass combined with strong winds at higher elevations will produce conditions favourable for waterspouts over the BC inner south coast. These conditions will develop early this morning and persist until the afternoon.

Wind speeds inside the spray ring of a waterspout are 45 knots or higher. Vulnerable vessels are at risk of damage or capsizing. Waterspouts sometimes appear as funnel clouds with swirling water visible near the surface.

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