Marine
Winds over the coastal waters continue to ease. Will allow Exercise Caution headlines to drop out. While some elevated observation sites could stay just above 15 knots for a few hours, all should be below 15 knots prior to next forecast issuance. 35

AVIATION...North winds at all terminals with gusty winds up to 20 to 25 mph at NEW and MSY through late afternoon with winds tapering to less than 10 to 15 at NEW and MSY to light and variable at remaining TAF sites after 00z this evening. SKC will dominate sky conditions with VFR conditions prevailing the remainder of period.

Marine Discussion
Small Craft Advisory will expire at 6pm for the coastal waters. Offshore flow will continue to weaken through Saturday. High pressure will remain in place through the weekend. Surface High will move off the Carolina Coast by Sunday evening bringing a light return flow. Return flow will remain in place through early week until another arctic front moves through by the middle of next week. This will likely bring a minimum of Small Craft Advisory conditions to all waters once again.
