...ACTIVE WET WEATHER POISED TO RETURN TO NORTHERN PANHANDLE...

There is increasing confidence in the mid and long range model
solutions that a pair of atmospheric rivers will track into eastern
half of the Gulf of Alaska and panhandle. The first feature will
spread in its moisture band ( 1 to 3 inches ) and warming into the
area Monday to Tuesday. Snow levels warming to around 3000 ft or
higher. Rainfall event totals through around Wednesday/Thursday are
4-6 inches while NE Gulf coast may be closer to 8 inches of
potential. Rain on top of new snow creating melt and run off will be
the forecast challenge with the first system.

The second feature is as strong or stronger and expected Thursday
and Friday. Snow levels will rise higher  (4000 to 5000 ft ) and
additional rain ( 2 to 4 inches more ) will add more snowmelt.
Streams will be rising quickly with the first system, and localized
flooding due to drainage issues are possible. Significant river
rises are more likely with this second event as the first event
primed the river and soil conditions to possible produce bankful to
flooding conditions.
