Issued 3:50 AM PST 5 December 2016 A low pressure system west of Haida Gwaii is slowly moving southward.
Gale force northerly or northwesterly winds will continue over the
offshore waters today and tonight. The winds will ease overnight as
the low moves to Washington coast and weakens.

A quasi-stationary ridge of high pressure over the BC Interior in
combination with a low pressure system over the BC waters will
produce gale force outflow winds through the mainland inlets. Cold
temperatures from the strong Arctic outflow winds will give a risk of
moderate freezing spray through the mainland inlets overnight
