SYNOPSIS

Key Messages:

- Strong winds in the northern panhandle will continue to decrease through the evening, with light rain possible for the rest of the panhandle overnight.

- Generally improving conditions expected with potential for a brief break into Saturday morning.

- A new gale force front will approach the southern panhandle Saturday night, increasing outflow winds through the inner channels Saturday as it approaches.

LONG TERM

/ Tuesday through Saturday / The remains of the Monday system will be pulling away to the NW Gulf and the remains of the weather front will be sweeping through the panhandle and NE gulf coast. The midrange solutions think that there will be a secondary system pulling to the far SE of Gulf of Alaska to Haida Gwaii with its associated rain and some wind. Wednesday is hinting at yet another system to push into the gulf that will usher in another fall storm to Southeast Alaska. Fall has decided to stay with the active weather pattern.

AVIATION.../Through 06z Sunday/

Showers continue across the area creating variable flight conditions for SE AK. Areas across panhandle, especially over the south, are starting to see more of a break in those showers with some areas seeing lowest cloud bases around 5000 ft or higher. As showers persist tonight some areas will continue to see a scattered deck, at times broken, around 1500 to 2500 ft. By late Saturday morning most areas are likely to have predominately VFR conditions. Just as that happens, another low will move northward toward the southern panhandle. This will not only bring rain and lowered clouds back to the area, it will also once again increase winds.

Winds currently have begun to relax across the area with the exception of Haines and Skagway where gusts to 30 to 40 kts will continue into early Saturday morning. Winds across the area will be below 10 kts before low moves NW and once again increases winds. This low will not only increase winds, it will also create a change in wind from southerly to northerly. Once again strongest winds will be over Skagway, but multiple areas will see wind speeds and gusts increase. LLWS is also likely over Prince of Wales Island Saturday afternoon and evening.

MARINE

Outside (Gulf and Coastal Waters): The low passing SW of Yakutat this evening will move east and gradually fill/weaken through morning. This will leave us with a broad southwesterly flow 20 kts or so by morning with 15 ft seas mostly a SW-SE swell. We see another low to gale force moving up out of the north Pacific tomorrow bringing another round of 25 to 35 kt sustained winds with higher gusts to the Dixon Entrance region by tomorrow afternoon. We continue with Gale Warnings for the Dixon Offshore zones starting tomorrow and those will possibly spread a bit further east to the southern Panhandle by Saturday night. Looking further out, the main thing to watch the next few days will be a stronger low moving up out of the north Pacific Monday. Most models bring this low down to around 955 mb as it strengthens/deepens over the central Gulf of Alaska Monday into Tuesday. This could mean storm force winds to the central and eastern Gulf of Alaska zones Monday into Tuesday. Stay tuned for further update. /Garmon

Inside (Inner Channels): The low moving west of Yakutat tonight will result in a gradual weakening of winds over the northern Panhandle overnight into Saturday, however as the low to the south moving up towards Haida Gwaii tomorrow deepens a bit, and the high over the Yukon strengthens a bit, we will see an increased northerly flow over the northern Panhandle north to south facing waters tomorrow afternoon and evening...and we have Small Craft Advisories for Saturday posted for those zones. To the south, the low moving up near Haida Gwaii on Saturday will result in an increased wind flow over Clarence Strait, hence the Small Craft Advisories there for tomorrow as well. 05/Garmon
