A strong ridge of high pressure will persist over B.C. through this week. Moisture trapped under a temperature inversion will result in extensive areas of dense fog. The fog may become patchy during the afternoons away from the water.

If travelling, be prepared for areas of near-zero visibility.

Fog advisories are issued when near zero visibility in fog is expected or occurring.
