UPDATE...Update to include the 18Z TAF issuance

Minor edits to the forecast this morning. Moderate to heavy snow is building into central panhandle with visibility down to a mile or less at Sitka, Kake, Petersburg and Wrangell. Warnings and advisories start times were bumped up as the heavier snow built in bit sooner.

MARINE

Outside (Gulf and Coastal waters): As of 0300 Sunday morning a sub gale force low was making landfall in the central region, driving westerly winds of moderate to fresh breezes for the eastern Gulf. Outflow was starting to dominate, with easterly winds of strong breezes starting to push out of major gaps/inlets along the coast. Seas state, choppy, with the primary wave energy out of the WSW and significant heights of 5 to 9 ft with a period less than 10 seconds. Moving through Sunday, northeasterly outflow continues to dominate major bays/inlets along the northern coast from Cross Sound toward Cape St. Elias. South of Cape Decision we will likely see onshore southwesterly winds of moderate to fresh breezes. A gale force low moves into the central gulf late Monday into Tuesday with winds turning southeasterly from Cape Edgecumbe south. This low will help tighten up the pressure gradient, with outflow winds increasing out of major inlets along the coast. Gale force conditions are likely in the vicinity of Cross Sound/Palma Bay and Dangerous River Monday into Tuesday.

Inside (Inner Channels): Northerly outflow winds remain the primary threat over the next 48 hours for the inside. Anticipate northerly outflow of at least strong breezes for areas along and north of the Icy Strait Corridor, with two distinct peaks of gale force conditions; the first being Sunday afternoon into Sunday night and the second, Tuesday, as a gale force low lifts into the central gulf. Strongest winds will be in Glacier Bay, Lynn Canal, and the four corners area. Mariners navigating these areas should be aware of fully developed seas of 8 ft in Lynn Canal moving south into Northern Chatham Strait, along with freezing spray. The secondary threat Sunday into Monday will be periods of heavy snow in the central Panhandle, especially near Angoon, Petersburg and Wrangell, reducing visibility to below 1 mile at times.
