Marine Weather and Tides
Emmonak, AK

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Discussion
An unsettled pattern will continue for the next few days along the
west coast while warm and relatively dry weather is expected for
much of the interior.

Aloft, at 500 mb, a 544 dam low centered over nunivak island will
slowly move to the west over the next few days. A ridge will
continue to build over the interior and arctic coast tonight into
Thursday. This ridge will be pushed to the east on Friday as a
low moves to to the north in gulf of alaska.

Central and eastern interior: warm temperatures are expected to
continue for Thursday with temperatures in many locations in the
tanana and yukon river valleys reaching the upper 70s, with some
locations reaching 80 degrees. Isolated afternoon and evening
thunderstorms are possible tomorrow across much of the interior as
a front moves north through the interior. Scattered thunderstorms
are possible tomorrow along a line from eagle to livengood where
the models are showing an area of higher instability with cape
values in excess of 1000 j kg along with negative LI values. Winds
tomorrow afternoon are expected to kick up in the alaska range as
a thermal trough just north of the range intensifies. Friday will
be cooler across most of the interior. Rain showers are expected
across much of the eastern interior on Friday, some of which
could be locally heavy; however, at this point there is not a lot
of consistency between the models in the placement and exact
timing of the heaviest precipitation.

West coast and western interior: a weather front will move north
across the west coast late tonight into Wednesday. This will bring
locally heavy rainfall to the yukon delta and lower yukon valley.

Scattered showers will continue on Friday.

North slope and brooks range: temperatures are expected to
continue to warm over inland areas with the ridge of high
pressure moving over the brooks range tomorrow. A shortwave will
move to the north on Friday. This will bring more rainfall to the
brooks range and cooler temperatures. Low level stratus and fog
is expected to continue along the coast.

Coastal hazard potential days 3 and 4... None.

Fire weather
A thermal trough will strengthen tomorrow over the tanana valley.

This will cause the winds to pick up on the north side of alaska
range. High temperatures tomorrow will be warmer with many
locations in the tanana and upper yukon valleys reaching reaching
into the 80s. Minimum relative humidity values will drop below 25
percent across much of the tanana valley. Red flag conditions are
expected in the vicinity of delta junction tomorrow afternoon. We
issued red flag warnings for zones 223 and 226 for Thursday in
anticipation of the hot, dry and windy conditions. A front will
bring isolated to scattered thunderstorms late tomorrow afternoon
and evening across much of the interior. This will likely bring a
lot of lightning activity to portions of the eastern interior
tomorrow evening. We issued red flag warnings in anticipation of
the lightning for Thursday evening for zones 220, 222 and 224.

Cooler and wetter conditions are expected on Friday behind the
front.

Hydrology
Warm temperatures aloft over the brooks range combined with heavy
rainfall over the last several days and additional rainfall
expected over the next couple days will produce significant rises
on rivers draining the brooks range and in particular the sag
river. Current forecasts keep the sag river below action stage,
but we will need to monitor closely as additional rain falls over
the brooks range. Recent heavy rainfall will keep many of the
smaller creeks and streams in the west coast and western interior
running high over the next few days.

Afg watches warnings advisories
Red flag warning for akz220-akz222-akz223-akz224-akz226.

Small craft advisory for pkz210-pkz220.

GOES Local Image of Alaska    EDIT
NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
