Southeast Alaska Forecast Discussion National Weather Service Juneau AK 525 AM AKDT Tue Apr 22 2025

SHORT TERM
/Through Wednesday Night/...A weather system that brought rain to the Panhandle-mainly across the northern two- thirds-starting Monday evening and overnight will begin to ease later on Tuesday. Meanwhile, a new low-pressure system is forming over the Gulf of Alaska and will push a front into the northeastern Gulf and northern Panhandle. On Wednesday, the heaviest rainfall is expected in the northern Panhandle. Rainfall during the day is forecasted to range from a quarter to two-thirds of an inch, with similar but slightly lower amounts expected overnight. While flooding isn't a concern, these amounts are a bit above average for April, which is typically one of Southeast Alaska's drier months. Remnants of the low will linger in the Gulf, bringing continued showers Wednesday night into early Thursday.

LONG TERM
/Thursday through Monday/...For the late week and weekend dealing with the uncertainty of where the Wednesday Gulf low will track. There have been two main tracks depicted by operational models and the ensembles. One keeps the low in the NE gulf, stronger and longer, thus continuing Eastern Gulf winds and Panhandle shower activity well into Friday and possibly Saturday. The other track drops the low to the SE along the panhandle coast, with a faster drying trend for the northern regions and SE Gulf winds staying up.
For the morning operational models more lined up with the northerly track (ECMWF. NAM, Canadian), with GFS dropping to the south, but keeping the low intact will into Saturday. Run to run consistency with these models isn't helping and ensembles while not as diverse still are not exactly lined up. Keeping with a mostly cloudy chance of rain forecast with this uncertainty, for now. For the weekend a wide range of solutions for upstream features. Another surface low and associated front is expected in the western gulf and impacting SE AK Monday into Tuesday. If the low center remains further west it will be keep precip for the region but would not anticipate much in the way of elevated winds. Low forecast confidence is still the word, so expect details to change as hopefully a steadier trend develops.

AVIATION
/Until 12Z Wednesday/...Front draped over the panhandle will continue to bring showers and low CIGs to a majority of the panhandle Tuesday. CIGs range from around 3000 ft to below 1000 ft for some coastal communities, particularly the far southern panhandle this morning. Surface winds remain relatively light across the board with no expected LLWS for the period. Some improvement is likely through the day though MVFR conditions will dominate. Stronger front set to impact the panhandle Wednesday morning bringing more moderate to heavy rain to the outer coast, and LLWS primarily to the central and southern panhandle.

MARINE
Winds are expected to remain below 20 knots, and sea conditions in the outer waters will stay near or just under Small Craft Advisory levels until a new front moves through the eastern Gulf and approaches the Panhandle on Wednesday. This system will bring Gale-force winds to the northeastern Gulf of Alaska, with 25 to 30 knot winds-meeting Small Craft Advisory criteria-spreading out from that area into the rest of the eastern Gulf and the ocean entrances of the Inner Channels.

AJK WATCHES/WARNINGS/ADVISORIES
PUBLIC...None.
MARINE...Gale Warning for PKZ672.
Small Craft Advisory for PKZ643-644-651-652-662>664-671.
