.Synopsis for Hawaiian coastal waters...
A trough of low pressure northwest of Kauai, will continue to

islands strengthens. This will lead to strengthening trades across
the waters today, with fresh to strong trades expected Wednesday
through Friday. The trades could ease slightly this weekend, as
high pressure to the north weakens.
