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.

northern alaska forecast discussion

Discussion
Significant rainfall over the eastern interior beginning tonight
and continuing through Thursday morning will be the main forecast
concern through the memorial day weekend as rivers in the central
and eastern interior rise.

Aloft at 500 mb a deep longwave trough over alaska with an anchoring
527 dam low over the central gulf of alaska will sweep a series
of moisture laden shortwaves north and west out of the northeast
gulf of alaska into the southeastern interior, especially over
the good pastor, salcha, and chena river basins as well as the
eastern alaska range through Thursday.

Computer models continue to indicate storm rainfall totals of one
half inch to one and a half inches along a line from paxson to
delta junction and northeast to near eagle through Thursday
morning. Freezing levels are expected to be between 5 thousand and
6 thousand feet during the day and near 4 thousand feet at night.

Higher elevation snowpack is still significant with snow water
equivalent in excess of 3 inches at munson ridge east of
fairbanks. Expected rainfall combined with elevated freezing
levels and rapidly melting snowpack will produce significant rises
on small streams and rivers in the central and eastern interior
as well as the eastern alaska range into the memorial day weekend.

Will need to closely monitor rainfall and snowmelt and water
levels on rivers in the central and eastern interior. A flood
advisory has been issued for the chena river near milepost 38 on
chena hot springs road through Tuesday evening with gauge reports
indicating that the chena river is nearing minor flood stage.

River levels are likely to remain high through the week and into
the memorial day weekend. Those with holiday plans on or near
central or eastern interior rivers will need to closely monitor.

The shortwaves rotating northwest around the low in the central
gulf of alaska will stall over the central interior and will be
the focal point for showers as well as isolated thunderstorms
along an old crow to fort yukon to fairbanks to mcgrath line
Tuesday afternoon and evening. Some of these showers may produce
locally heavy rainfall.

Low ceilings and fog is expected on the north slope with east to
northeast winds around a large high pressure system to the north
of the state. Troughing over the west coast will bring periods of
clouds and Sun to the area. Isolated to scattered showers are
expected for the upper kuskokwim and middle yukon valleys.

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

Fire weather
Shower activity today will be mostly south and east of ruby.

Isolated thunderstorm activity today will primarily be along a
line from old crow to eagle to fairbanks to mcgrath. Lowest
relative humidity values will be around 30 percent Tuesday in the
yukon flats. Minimum relative humidity levels are expected to
remain in the 30s and 40s over the rest of the interior. Winds are
generally expected to be less than 15 mph through Wednesday.

Hydrology
Satellite imagery continues to indicate overflow flooding from
the sag river near dalton highway milepost 386, however local
reports indicate no impacts at this time, so will continue to
monitor the area.

Significant rainfall in excess of an inch and a half combined
with rainfall that occurred yesterday, high freezing levels and
still significant snowpack in the higher elevations of the eastern
interior will produce increased water levels on small streams and
rivers in the central and eastern interior through the memorial
day weekend. Those with holiday plans on or near central or
eastern interior rivers will need to closely monitor.

Afg watches warnings advisories
Flood advisory for akz222.

Heavy freezing spray warning for pkz230.

Small craft advisory for pkz225-pkz230.

Brisk wind advisory for pkz240.

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.
