600 am akdt Thu Aug 20 2015

... Another round of rain and wind late Friday and Saturday...

A potent low pressure system and associated weather front will move
into the Panhandle late Friday and into Saturday. This will bring
another period of moderate to heavy rainfall and gusty winds to
Southeast Alaska. Total rainfall amounts will range from 1 to 3
inches. Southerly winds will increase Friday night and Saturday
with gusts of 30 to 45 mph over much of the area. Winds are
expected to begin to subside later Saturday and Sunday.

Moderate to heavy rainfall combined with strong winds will result
in an increased risk of mudslides. Area rivers... creeks and streams
will also rise as a result. Antecedent conditions combined with
significant rainfall could result in minor flooding.

NWS Forecaster Discussion




Southeast Alaska forecast discussion 
National Weather Service Juneau Alaska 
353 PM akdt Thursday Aug 27 2015 


Short term...the Panhandle is becoming gradually wetter as the 
day wears on. An upper level trough is dropping southeast from the 
Alaska Peninsula and is dragging what is left of an atmospheric 
river that was drawing significant tropical moisture into SW 
Alaska for the last two days. While the remains of this moisture 
stream are not as potent as when it was in the Bering, precipitable water values 
are still registering around 1 inch or 120 to 140 percent of 
normal across the Gulf. At the surface the upper trough is 
spinning up a surface low in the northern Gulf with a front that 
is spreading across the eastern Gulf. The initial heavy rain bands 
have been in Yakutat most of the morning and have just reached the 
northern Panhandle just after noon. These rain bands will spread 
into the central and southern Panhandle by this evening. 


Winds have also started to kick up across the northern Panhandle with 
gusts to 33 knots at Skagway, 39 knots at Eldred Rock, and gusts to 25 
knots at Juneau being the highest observed gusts so far. These winds 
will remain gusty through the evening but will gradually subside 
by late evening. The southern Panhandle will be the opposite as 
winds will be increasing this evening as the front approaches that 
area. As a result small craft advisories and a few strong wind 
headlines remains up in various areas of the Panhandle tonight. 


Into tomorrow the rain will be lightening up across the north but 
will be continuing and be heavy at times across the southern 
Panhandle as the front stalls. Areas from around Kake and Cape 
Decision eastward will see the brunt of the heavy rain on Friday with 
upwards of 2 to 3 inches expected through Friday afternoon. Winds 
will also remain gusty with small craft winds continuing for 
Clarence Strait tomorrow but they should remain below strong wind 
criteria. 


Behind the low, winds switch around to the north and with a cool 
high pressure system strengthening in the Yukon some outflow winds 
will be blowing out of the usual passes in the northern Panhandle. 
Expect winds to reach small craft criteria Friday morning but I do 
not expect anything higher as the pressure gradient is not that 
strong and the air mass in Canada is cool not cold plus the 
strongest part of it is over the Alaska interior farther west. 


Short range models were in good agreement through the period with 
only a few differences noted here and there. Generally used hi-res 
NAM for updates today. 


Long term.../ Friday night to Thursday / the short wave aloft 
that moved south to the Gulf of Alaska through Friday will help 
to open the closed low that had been persisting about 600 nm west 
of the Continental U.S. Coast around 43n. The newly reformed trough will be 
'open' early Saturday. The short wave feature is next expected to 
lift the southern end of the trough inland across the Pacific 
northwest through early Sunday morning. 


Another short wave moving southeast across western Alaska should 
reach the western Gulf early Sunday morning and be moving into the 
southeast Gulf by Sunday afternoon. Middle Range models solutions 
are beginning to converge on a more organized solution for Sunday 
however there remain some issues. It does looks like a low will move 
across the southern Panhandle Sunday and Sunday night. 


Do expect another burst of middle tropical moisture to work its way 
back into the Gulf in a round about way from the southern Bering 
Sea for the weekend. That moisture will be tapped for the Sunday 
feature to spread more rain over the southern Panhandle. Best 
rains may end up south of the Panhandle but will need to watch this 
to see if the low track could be little further north...in which 
case the southern Panhandle will get another soaking. For the moment 
quantitative precipitation forecast numbers are not that out of Ordinary for an early Fall storm 
feature. 


Building ridge aloft and at surface along roughly 160w will build 
east from the early part of the week to be over the Gulf by 
Wednesday night. Therefore the tapering off the precipitation and 
drier pattern middle week still looks very possible. 


The forecast adjustments to Sunday night were based on a blend of the 
European model (ecmwf) and NAM in mind. Confidence is good lowering to average headed 
into weekend. 




&& 


Hydrology...the moderate to heavy rainfall will make area rivers 
and streams rise over the next 24 hours. The taiya river and Montana 
creek have the possibility of reaching bankfull this evening as the 
initial front moves through but that is about it for the gaged 
rivers and streams. Smaller non-gaged streams may reach bankfull 
later tonight and tomorrow especially across the southern Panhandle 
as the front stalls. 


&& 


Ajk watches/warnings/advisories... 
public...strong wind until 10 PM akdt this evening for akz025. 
Strong wind until 4 PM akdt this afternoon for akz018. 
Marine...Gale Warning for pkz012. 
Small Craft Advisory for pkz011-013-022-031>036-041>043-051-052.
