When: This afternoon and tonight.

Additional Information:
An upper trough will move across the south coast of B.C. today, bringing a cool and unstable airmass. This airmass will provide favourable conditions for the formation of waterspouts across the Strait of Georgia and the mouth of Howe Sound, as well as the west coast of Vancouver Island this afternoon and tonight.

Mariners are urged to take all necessary precautions and prepare for the possibility of waterspout activity. Postpone voyage or seek safe harbour if possible. Keep in mind that waterspouts cannot be seen at night and may strike suddenly.

exits the region.

In addition, this trough will create conditions favourable for the
development of waterspouts across the Strait of Georgia, Howe Sound

A transient ridge of high pressure builds over the offshore waters on
Saturday. As the ridge nudges closer to the coast, gale force
westerlies will develop through Juan de Fuca Strait Saturday
