AREAS AFFECTED : KETCHIKAN GATEWAY BOROUGH; ANNETTE ISLAND
Following a front bringing rain across the panhandle Sunday, a
fast developing low is expected to move into the SE gulf Monday
into Tuesday. This system is expected to bring enhanced rainfall
to the far southern panhandle, particularly Ketchikan and
Metlakatla. Model spread in the track of this feature suggests two
primary solutions, with the more impactful solution bringing the
low on a more northerly track, skirting the outer coast. The less
impactful solution would see the low be more progressive and not
track as far north before moving inland into Canada.
The more impactful solution would bring 24 hr totals of at least 1.0
to 2.5 inches of rainfall to Ketchikan and Metlakatla along with
strong breezes up to near gales (30 kt) into southern Clarence
Strait as well as the coastal waters from Dixon Entrance northward
to Cape Decision. Heaviest rainfall is expected along southerly
facing mountains. The less impactful solution would still see
periods of heavy rainfall with overall lower totals, along with
lower winds for Clarence Strait and the SE gulf. Rivers and lakes
may reach bank full conditions but no flooding is expected at this
time.
