Marine Weather Statement

Issued 10:24 AM PDT 14 April 2026 The cold front will continue to move through southern waters today.
This will give a brief period of marginal northwesterly gales between
late afternoon and tonight over West Coast Vancouver Island South,
Johnstone Strait, and Juan de Fuca Strait.

Northwesterly gales are expected over the offshore waters today and
Wednesday as a ridge of high pressure strengthens over the Pacific
Ocean.

As the ridge of high pressure approaches the British Columbia Coast
on Wednesday, northwesterly gales will likely occur again on
Wednesday afternoon and evening over Johnstone Strait and West Coast
Vancouver Island South.

Additionally, the cold front is bringing the risk of thunderstorms to
portions of the southern waters this afternoon and evening. A trough
behind the cold front, will bring a risk of thunderstorms to the
central and northern waters tonight, and a risk of thunderstorms to
the southern waters Wednesday morning and afternoon.
