swell. A high to the north and a trough to the east will produce
strong to near- gale force northeast winds for most waters, and
gales for the Alenuihaha Channel through tonight as well. Seas
will decrease as the swell subsides and winds will diminish as the
trough moves over the area Friday into the weekend.
