Generalized Statewide Coastal Waters Forecast for Hawaii
National Weather Service Honolulu HI
303 AM HST Tue Nov 21 2017

.Synopsis for Hawaiian coastal waters...
Winds will veer slightly to the northeast today as low pressure
northeast of the state weakens and moves farther away, while a
lingering north swell keeps seas elevated. Strong high pressure
will build northwest of the area during the second half of the
week, resulting in strong and gusty northeast trade winds over the
coastal waters. Another large north swell is expected to move
through the area beginning late Wednesday and continuing through
Thursday night.
