Flood Watch issued September 18 at 2:52PM AKDT until September 21 at

A series of low pressures will move through the panhandle this
weekend bringing prolonged rain combined with high freezing levels to
increase ice melt on glacier river systems. The heavy rainfall and
associated runoff will produce significant river rises with the
potential of minor flooding.

* WHAT...Flooding caused by excessive rainfall is possible.

* WHERE...Including the following area, Northern Inner Channels. This
includes the cities of Skagway, White Pass, And Haines.

* WHEN...From late Saturday night through late Sunday night.

* IMPACTS...Excessive runoff may result in flooding of rivers,
creeks, streams, other low-lying areas and flood-prone locations.

* ADDITIONAL DETAILS...
- A series of lows will bring a prolonged period of rain combined
with warmer temperatures aloft allowing for any precipitation
falling into the region to remain as rain. Current thinking is
that the rain will continue this evening into Saturday before a
second, stronger system moves in for Saturday into Sunday.
Between the two systems, the flow is expected to remain onshore
keeping moisture moving into the area.

For the Skagway area, 24 hour precip looks to get up to 1 to 2
inches this weekend while the storm total amounts could be 2 to 4
inches. The Haines area is expected to see 0.75 to 1.5 inches in
24 hours while a storm total precipitation of 2 to 3.5 inches is
possible.
