.SYNOPSIS...
Small Craft Advisory conditions continue as a strong cold front
moves across the coastal water tonight with breezy northwesterly
winds and elevated seas. Winds subside and shift to northerly on
Tuesday afternoon and then northeasterly by Wednesday as high
pressure shifts northeastward towards the Mid-Atlantic coast. This
strengthening high pressure center will wedge down the southeastern
seaboard later this week, creating another round of Small Craft
exercise caution conditions on Wednesday night and Thursday. Winds
and seas are expected to diminish by Friday afternoon.
