A strong weather front with sub-tropical connections will sweep
into the gulf and Southeast Alaska Monday night during the last
hours of November. The upper level flow pattern will allow for a
slow eastward progression through the eastern gulf and panhandle.
A wave or two developing on the frontal band running north will
also stop eastward movement or even pull the front back westward
slightly. This results in the atmospheric river being very slow to
exit the forecast area.

The majority of the focus of the moisture streaming onshore is
aimed at the northeast gulf and northern panhandle. At this time
best precipitation is between a line from southern Baranof Island
to Endicott Arm westward to Icy Bay.

This has the looks of an exceptionally wet system that we will be
watching for potential flooding and the other hazards the that
accompany excessive rains, such as mudslides. Between Monday
evening and Thursday morning, 24-hour rain totals look to range
between 2 to 5 inches each day, or an event total between 5 and 11
inches potentially.

We will continue to monitor this potential dangerous storm and
coordinate with the River Forecast Center for future hydrological
