Severe Weather Alert Descriptions

 Special Statement  Statement as of 2:41 PM AKDT on April 29, 2016


... Heavy rain and strong winds to impact the Panhandle this
weekend...

A stream of subtropical moisture from the North Pacific will
result in heavy rainfall over much of the area Saturday through
Monday. Rain will quickly spread across the Panhandle on Saturday
before concentrating over the southern Panhandle Saturday night.
On Sunday the heaviest rain bands will likely return
northward... potentially persisting through Monday. Two to four
inches of rainfall is expected across the region with locally
higher amounts. Current water levels are low on streams and rivers
in Southeast Alaska but significant rises are anticipated with
this event. Even though flooding is not expected at this time... any
threat of flooding will continue to be monitored.

Strong gusty winds will also occur with this storm especially on
Saturday across much of the Panhandle... and potentially for
Sunday and Sunday night as well... as a low travels northward
across the Gulf. Gusts of 40 to 50 mph will impact the coast while
40 mph gusts will affect portions of the interior Panhandle on
Saturday.

NWS Forecaster Discussion




Southeast Alaska forecast discussion 
National Weather Service Juneau Alaska 
425 am akdt Sat Apr 30 2016 


Short term...our storm force front advances quickly from the 
central Gulf and will bring wind and heavy rain to Southeast 
Alaska today. The strongest portion of the front will reach the 
northern Gulf by the afternoon affecting Yakutat with gusts up to 
40 miles per hour late this afternoon. The eastern portion of the front will 
be weakened by the terrain somewhat, but gradients across the 
central Inner Channels will be sufficient for solid small craft 
southeasterlies and for the southern Panhandle and Cross Sound for 
gales. 925 mb southeasterly jet of 40 to 55 knots impressively 
spreads across around 80 percent of the Panhandle with all but the 
far northern Inner Channels covered. For this reason, we have 
added strong wind headlines for many locations in the northern and 
central Panhandle that were not covered previously. Airport 
locations may not verify 40 miles per hour wind gusts, but in more exposed 
spots, it will be windy. In our recollection it has been many 
weeks since the Panhandle has experienced such a widespread wind 
event, although it must be noted that we are not expecting 
damaging high winds of 60 knots or greater. Nonetheless, there will 
likely be impacts. The front will stall over the central 
Panhandle tonight, and gradients and winds will relax...although 
ridging over the northern interior should push winds in Skagway 
and Lynn Canal higher Saturday night than Saturday itself. 


The other story continues to be the rain. Rain bands will be heavy 
at times today Panhandle-wide as the front initially pushes 
onshore. But as it stalls over the south tonight, the highest 
precipitable water will remain over Prince of Wales Island and the 
southern Inner Channels...therefore high rain rates will persist 
here while areas north and west of Petersburg and Kake should see 
lighter totals with widespread showers tonight. Naefs mean 
precipitable water fields boost confidence in higher rain amounts 
with values of 4 plus Standard deviations above normal for this 
time of year over the southern Panhandle. All told the northern 
Panhandle should receive anywhere between a half to 1.5 inches 
today, while the south will more than outdo the north with 1 to 3 
inches. Rivers and streams...especially over the south will rise 
significantly over the next 24 hours, especially tonight, but 
flooding is not expected. 


The only real change to the forecast was expanding the area of 
strong winds to Yakutat, Hoonah, Angoon, and Elfin Cove. We also 
moved up some of the onsets before noon in western portions of the 
Panhandle. Few changes needed. We will let the Special Weather Statement expire. Its 
message has been absorbed by the public and the time is nigh. The 
forecasts are stamped firmly with rain and strong winds. 
Confidence good to average. 


Long term...the front will be stalled over the southern Panhandle 
at the beginning of the extended range on Sunday morning. A wave of 
low pressure will develop and move into the eastern Gulf Sunday 
afternoon into Sunday night. The wave will then move inland near 
Yakutat early Monday. There remains timing differences with this 
wave as the NAM/GFS are 6-9 hours quicker than the European model (ecmwf). Based 
upon this opted to stay the course with the previous forecast which 
represented the NAM/GFS solution well. The wave will enhance 
rainfall rates again over the southern Panhandle Sunday afternoon 
and this heavy rain will progress northward reaching the northern 
Panhandle Sunday night into early Monday. Precipitable water values 
reach 1-1.1 inches which is 4 Standard deviations above normal for 
early may which indicates that heavy rain is indeed likely. Another 
period of gusty winds will accompany the wave especially as it 
moves inland early Monday with significant pressure rises occurring 
over the Panhandle. Rainfall totals are expected to range from 1-3 
inches for the Sunday through Monday morning time frame. 


The weather pattern will be much quieter after Monday with a 
surface ridge of high pressure building into the area and 
decreasing precipitation chances by middle week. Models indicate 
another front will move into the Gulf by late week. However there 
are differences in the strength of the ridge and how much eastward 
progress this front is able to make. 


Used the 00z NAM/GFS for updates through day 4 then continued with 
wpc guidance for the remainder of the forecast.
