.Synopsis for Hawaiian coastal waters...
A ridge of high pressure will linger near the islands through
tonight. A giant northwest swell will build rapidly today, then
gradually decline on Sunday. A strong front is expected to move
down the island chain late Sunday and Monday. The front will
likely stall over the eastern half of the state initially, with
associated moisture drifting west later in the week as the front
gradually dissipates.
