Marine Weather and Tide Forecast for Hyder, AK

SYNOPSIS...

Key Messages:

- Periods of moderate to heavy rain continue into Monday as a stronger system pushes from west to east across the panhandle.

- Slow drying trend from NW to SE next week; with widespread warmer weather and drier conditions likely late in the week and over the weekend.

SHORT TERM
/Through Tuesday night/
A strong front is currently draped along the outer coast of the panhandle, continuing moderate to heavy rainfall and gusty winds through Sunday afternoon and overnight. The northeastern gulf coast saw the brunt of the rain Sunday morning, receiving around 2 inches in the last 12 hours. The front is now moving inland up north, allowing the heaviest rain rates to begin to taper off through the afternoon. As of the time of writing, light rain has reached much of the northern and central panhandle and will continue to push east into the southern panhandle overnight. Winds are expected to flip southeasterly and increase as the front continues to push inland, but should largely decrease overnight.
QPF was bumped for Ketchikan and much of the interior panhandle along the coastal range, as the moisture plume looks to shift southeastward into the southern panhandle through Monday morning.
Expecting up to an inch for many locations along the interior panhandle the southern panhandle, reaching up to 1.5 inches for locations at higher elevations.

Rainfall will taper off overnight and through early Monday morning along the outer coast, but may linger for the interior panhandle into Tuesday. Onshore flow in the gulf will allow cloudy skies and isolated to scattered shower development to continue Monday into Tuesday, though mid-level moisture looks to get cut off through the latter half of Tuesday. Other notable changes made to the forecast was mainly centered around the high temperatures for today, as increased cloud cover combined with the approaching front has limited temperatures from reaching their full potential.
Highs in the high 50s to low 60s are expected through Tuesday, with lows in the mid to low 50s.

LONG TERM
/Wednesday through Sunday/
An area of high pressure will develop in the Gulf of Alaska, and this will lead to onshore flow and a general warming and drying trend for Southeast Alaska. Some cloud cover and shower activity is expected to remain given the onshore flow, and that looks to continue through next weekend.

Thursday night into early Friday, a weak low pressure will become an open wave and bring a chance for scattered showers to the Panhandle.
Right now, the system looks to be fairly weak and quick moving. A high pressure system will develop behind this low, and lead to diminishing rain chances and warming temperatures. Highs on Saturday and Sunday look to be in the low 70s with fairly light winds for most, but some stronger winds (15-20 kts) in the eastern Gulf where the high pressure will lead to a tighter pressure gradient.

AVIATION...Most of the heavier rainfall has ended across the area with many places reporting MVFR or VFR ceilings and Vis this evening. Yakutat remains the exception with IFR conditions of 600 ft ceilings and 1.25 mile vis. As of 9 am the main band of rainfall has settled over the southern panhandle from around Frederick Sound southward though some lighter rainfall is in the northern inner channels as well. There is another surge of rain coming for the south in the next few hours as a weak low moves NE along the front. This will likely lead to ceilings and vis dropping to MVFR if they are not there already overnight.
Otherwise most other areas may have to deal with some fog or low clouds overnight before improving tomorrow. Clouds will still linger Monday for most areas with MVFR ceilings likely being the norm for most of the day and into Monday night, but any lingering rainfall will be on a diminishing trend through the day. Some breezy surface winds this evening with some gusts to 25 kt in the northern inner channels and along southern Clarence Strait. Those winds will diminish by Monday morning and will then stay mostly low through the day.

MARINE...
Outside (Eastern Gulf and Coastal Waters): Improving Conditions after Sunday night, as a front moves east and into British Columbia by Monday. Current SE flow along the coast will weaken and turn out of the NW through Monday and Monday night. Winds will diminish down towards 10-15 kt, with seas likewise subsiding from 9-12 ft down towards 5-7 ft. By Tuesday, flow turns more W, with winds remaining around 10-15 kt. Swell will remain out of the S through the first half of the week, although the Sunday afternoon heights of 4-8 ft will diminish to 2-3 ft Monday and Tuesday.

By Thursday into Friday, a strengthening low level ridge will bring NW flow in the SE Gulf and Dixon Entrance up to 20-25 kt.

Inside (Inner Channels): Winds are increasing as an advancing system results in winds turning out of the S and ramping up to 15-20 kt through the remainder of the Sunday. On Monday, winds will slowly diminish back towards 10-15 kt (still out of the S), and the system departs Southeast Alaska into British Columbia.
Winds will continue to diminish down to 5-10 kt for most locations on Tuesday, with the exception of Lynn Canal (which will see S wind of 15-20 kt), and Clarence Strait (NW wind 10-15 kt).
