LONG TERM

The deep low forming in the gulf is currently moving northeast with models dropping as low as 970mb as the front reaches the outer coast. A weak atmospheric river will provide plenty of moisture to help fuel this system and bring an end to the nice weather we've been experiencing. This front will be accompanied by strong gales and sea heights possibly exceeding 18 ft off the coast in the eastern gulf. This system is expected to bring elevated winds to the inner channels, with the potential for gales near channel entrances. Temperatures will continue to rise through this system before slowly falling through the next week. Precipitation associated with this system will impact the panhandle through Saturday peaking overnight into Sunday and lingering through the beginning of the week. The northern and central coastal regions will experience the onset first, as well as the highest accumulated amounts as the front moves eastward. Yakutat is expected to receive the most precipitation with 1-3 inches through the weekend. The majority of impacts will occur Saturday afternoon, and the active pattern is expected to continue through the rest of the week.

AVIATION.../Until 00Z Friday/

CIG & VIS conditions will remain within the VFR flight category, & generally benign SFC winds are in store for Southeast Alaska through the TAF period. The only appreciable variation will be between sea and land breezes. LLWS values will remain benign through the period.

MARINE

With the weak pressure gradient, Inner Channel winds should remain largely around light breeze, perhaps occasionally reaching moderate breeze through Thursday night. Marine winds and waves are expected to remain on the quiet side until the end of the week when a gale force front is expected to move into the Gulf by Friday. Seas are expected to increase along the outer coast with this front with peaks near 20ft along the outer coast Friday night before winds decrease again.
