.Synopsis for Hawaiian coastal waters...
Moderate to locally fresh trades will continue through the week

week. Moisture associated with a weak trough moving in on the
trade wind flow may bring a slight uptick in shower activity to
the coastal waters Tuesday into Wednesday. While the current

the Hawaiian coastal waters from the east, remnant moisture from
this system is expected to arrive potentially by Thursday, likely
bringing more showers.
