Urgency:
Future
Effective:
September 20, 2026 - 2:49am
Expires:
September 20, 2026 - 3:00pm
Description:
A series of low pressure systems 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 continues to be
possible.
* WHERE...The following area, Northern Inner Channels. This includes
the cities of Skagway and Haines.
* WHEN...Through late tonight.
* 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 light rain will continue Saturday evening before a
second, stronger system moves in for Saturday night into Sunday
morning bringing moderate to heavy rain fall. Rain showers will
then take over on Sunday that may bring occasional moderate to
heavy rainfall as well.
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.
Instruction:
Stay tuned to further developments by listening to your local radio,
television, or NOAA Weather Radio for further information.
Persons living along streams should stay alert and be prepared to
take action if a warning or advisory is issued, or flooding is
observed.
You should monitor later forecasts and be alert for possible Flood
Warnings. Those living in areas prone to flooding should be prepared
to take action should flooding develop.
