UPDATE...update for 18Z TAF issuance

Only minor edits to the forecast today. Cooler with decreasing clouds across the panhandle as front exits the area and marine layer burns off near the coast. Warming trends for Sunday into early next week.

MARINE

Inside waters (Inner Channels):

With clearing skies in the inner channels, low pressure in Canada, and high pressure with a marine layer in the gulf, sea breezes and stronger thermal gradients will be the general flow for the next few days. Westerly breezes up to 25 knots in Peril Strait, Icy Strait, backside of Douglas Island will follow slightly delayed diurnal trends. Similarly in the southern half of the panhandle, northwesterlies up to 15 knots will persist in a diurnal trend.

Outside (Gulf and Coastal Waters): High pressure is to build in the Gulf of Alaska through Saturday, and remain over the area well into next week. Therefore, persistent northwesterlies along the coastline up to 20 knots will continue. Highest wind speeds are expected south of Cape Edgecombe, with wave heights possibly exceeding 8 ft by monday due to the persistent stronger winds and fetch length. Currently not represented in the forecast, as confidence is not high enough for persistent 20 knot winds. With these wind waves largely dictated by the wind speed, and confidence is not high enough, small craft advisories were not issued yet. Furthermore, expecting mostly good visibility greater than 2 miles, as the marine layer looks to remain around 1000 ft or greater.
