.Synopsis for Hawaiian coastal waters...

A trough in the northwest offshore waters will continue to move

northwest as trade winds have begun to fill in across the coastal

waters from east to west. Trade winds will continue to strengthen

over the weekend as Tropical Storm Moke passes south of the state

through Sunday. However, seas greater than 10 feet will most

likely be over the eastern half of the coastal waters.
