Event narrative

Zone 24 has no snow measurements. Surrounding communities observed 4 to 8 inches of new snow.

Wider weather episode

A dissipating low pressure system was weakening over the central Gulf of Alaska on the afternoon of 11.23 as a secondary low began to rapidly develop well to the SW of Dixon Entrance. This second low developed to storm force and brought warm air and moisture over colder air at the surface over the northern Panhandle and Hyder. This center made landfall south of the Queen Charlotte Islands which allowed the arctic front to move south from Lynn Canal causing heavy snow for some areas of SE Alaska.
