&& .MARINE... High pressure continues to push into the region and the gradient along the coast continues to weaken along with the gradual ending of the cold advection. This all spells the weakening of the wind fields. So while the NE winds continue, but they will continue to diminish in intensity. Seas are also dropping as well with the relaxing wind field. So with this package will drop the sca headlines across the Lower Ches Bay, Currituck Sound and the 2 northern coastal zones. The remains sca flags will continue through 00z tonight and Midnight, but conditions may improve so that the advisories can be dropped early. The high becomes centered over western and central Virginia tonight and the high remains entrenched over the region through the remainder of the week into the weekend. There is a weak front that tries to move through the northern waters on Friday afternoon, which would turn the winds to the nw briefly and may kick winds up to the 10 - 15 kt range, but otherwise expect light winds and seas from Wednesday through the weekend. && .EQUIPMENT... The KAKQ radar will be down through Wednesday, October 18th for radome repairs. && .AKQ WATCHES/WARNINGS/ADVISORIES...
