.SYNOPSIS...

Southerly swell have now abating with NW wind driven seas
becoming dominate sets across the nearshore waters. That said,
forecast still calls for enhanced seas through this evening in the
20-60NM waters until the NW regime gradually broadens during the
overnight hours. Still believe these conditions to fall below SCA
criteria by tonight. Hereafter onshore flow will return overnight
Tuesday into Wednesday morning.
