southeast alaska forecast discussion
national weather service juneau ak
246 pm akdt Fri sep 22 2017

Short term Friday afternoon through Saturday night ... A weak
weather system will bring more rain to the southern panhandle
tonight while scattered to numerous showers continue elsewhere. As
the weak weather system moves off to the northeast tomorrow,
showers will be replaced by rain from the next front that will
arrive Saturday afternoon. This rain will encompass the entire
panhandle by early Saturday night and become heavy at times.

Storm totals from late Saturday afternoon through early Sunday
morning are currently forecast to range from 0.5 inches to
slightly more than 1 inch.

No significant winds associated with the weak weather system
tonight apart from a southeasterly winds to 20 kt in clarence
strait. Am also seeing southerly winds to 20 kts over lynn canal
owing to a stiff southerly pressure gradient over the far northern
inner channels. Winds over the eastern gulf will form up out of
the southeast late tonight and increase to small craft intensity
by Saturday afternoon.

No significant changes to most aspects of the previous forecast.

Did update pop to slow down the weak weather system tonight and
fine tune the timing of the Saturday night front. Adjustments to
qpf for similar reasons using a blend of 12z nam12 and a the
latest forecast from rfc. Overall forecast confidence is average,
trending above average.

Long term Sunday to Friday strong southwest flow from the
central pacific is moving onshore the british columbia coast,
catching the southern part of the panhandle on the northern edge
of the stream. There should be a wave trough moving inland late
Saturday to early Sunday for the panhandle. Another system with a
closed low will move to the haida gwaii area late Sunday night and
is expected to have a significant moisture pool with it and larger
rainfall totals.

For mid week a more general broad low should be lifting into the
west central gulf of alaska and stalling which should result in
continued troughs and weak fronts lifting onshore across the
panhandle, with there clouds and rain.

Overall a wet pattern should be expected for southeast alaska next
week.

Models solutions at the later stages, day 6 period and onward are
still having some consistency issues and the solutions were
wildly different so an ensemble solution was favored. We did
adjust winds towards the wpc solution in line with neighboring
office. Not many other changes were made to the long term grids.

Ajk watches warnings advisories
Public... None.

Marine... Small craft advisory for pkz042-043-051-052.

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.
