Marine Weather Statement

Issued 4:07 PM PST 8 December 2016 An Arctic ridge of high pressure will remain over the BC Interior

through mainland inlets. Cold temperatures from the Arctic outflow
winds will give a risk of moderate freezing spray near most mainland
inlets.

waters. The low associated with this frontal system will move over
