Southeast Alaska Forecast Discussion National Weather Service Juneau AK 519 AM AKDT Mon Apr 28 2025

SHORT TERM
A near-gale force frontal system has moved into the eastern gulf early this morning and will bring precipitation and high winds to the panhandle through today. Up to 35 knot winds are expected in the eastern Gulf and channel entrances as the front moves through the area, with 25 to 30 knot winds possible through the inner channels and southern coastal land areas. Winds diminish through tonight as the low moves inland and the pressure gradient relaxes before the next system enters the gulf tomorrow. Total rainfall of 1 to 2 inches is expected for a majority of SEAK with peak values in southeastern regions. Ketchikan has already received 1.2 inches of rainfall within the past 6 hours. Temperatures remain near normal with lows in the lower 40s and highs in the lower 50s.
The active weather pattern will continue through the week with the next front expected to reach the outer coast of the panhandle by Wednesday.

LONG TERM
/Tuesday through Sunday/ SE AK weather for the long range will continue to be a cool wet pattern. Upper levels keeping either a low or trough over the region, mainly advancing from a main low anchored over the Bering.
While there are short periods of ridging tracking in there are just no foreseeable long or substantial breaks in the next week, and from CPC outlook likely the next two weeks. Tuesday rain showers are one of those few times that breaks in precip may occur as the previous low / front moves inland and a ridge moves in.
Tightening pressure gradient increasing NS channel winds. Onshore flow keeps some shower activity Tuesday with next low/front moving in that evening. For now parent low stays further west so winds along this front reaching gale force. Still some model differences on position and timing so not enough confidence to fully commit on details. EFI puts more heavy precip into the region with long fetch of moisture from the south. Hydrology concerns with this next batch of heavy rain, especially if the earlier system rivers rises remain elevated. Rain lasts into the weekend as the parent low reaches the Central AK Gulf. Little change to previous forecast as it either remained in line with new model runs or there is still enough spread in operational model that a national blend still covers the gist of the long range.
