Panhandle today. A second low will cross Bowie this afternoon and is
forecast to pass to the northwest of Haida Gwaii tonight.

Gale force southeasterlies over most central and northern waters will
ease this morning as the first low moves off. However, as the second
low approaches, gale to storm force south or southeast winds will
redevelop. The cold front associated with the second low will move
down the coast to lie over Vancouver Island late Monday. Winds will
shift to moderate to strong northwesterlies once the cold front
passes.

Meanwhile, in the far south, winds will remain light to moderate
under a ridge of high pressure.
