These winds will quickly ease and become gentle across EE by the afternoon of the 06. More moderate Es will continue across Grids NN, OO, PP, QQ and RR. Swells are expected to build from N to S across Grids LL, KK, RR and QQ thru the 07, but will be mostly long period. The largest swells are expected to move across Grid EE, but will be long period (about 12-13 seconds) and will begin to abate by the evening of the 06/morning of the 07.
