A series of systems will be advancing across the
panhandle beginning Saturday and continuing through the end of
next week, bringing widespread active weather back to Southeast
Alaska. Impactful snow is looking to focus over the northern
panhandle, prompting the issuance of a Winter Weather Advisory for
Yakutat and a Winter Storm Watch for Haines, Skagway, Gustavus,
and Juneau. For further information on the snow threat please
reference the winter statement for your area.
An atmospheric river becomes directed at the northern gulf coast
Monday, then shifts eastward across the panhandle Monday night
through Tuesday. This will bring significantly warmer temperatures
and heavy rainfall. The exception will be the upper elevations
where significant accumulations is possible. Gusty winds will also
accompany this feature. A brief lull on Wednesday will be
followed by another system and atmospheric river late in the week.
River rises are possible with these two systems, along with
ponding and runoff in some locations as water flows off of frozen
ground.
Rainfall totals at sea level look to remain near 2 to 4 inches
for both systems. However, 3 to 4 day totals could reach 5 to 7
inches, namely along the northern coast.
