Hydrologic Outlook
National Weather Service Anchorage AK
259 PM AKDT Sun Sep 13 2026

...SIGNIFICANT RAINFALL BEGINNING MONDAY EVENING THROUGH WEDNESDAY
AFTERNOON FOR THE MATANUSKA AND SUSITNA VALLEYS...

Locations:

* Willow and Talkeetna
* Rivers, creeks, and streams with headwaters along the western
  Talkeetna Mountains

Timing:

* Monday evening through Wednesday afternoon. Heaviest rainfall
  expected through Tuesday evening.

Rainfall:

* Rainfall totals of 1 to 3 inches Monday through Wednesday likely
  won`t be high enough for widespread flooding, but smaller
  tributaries draining the Talkeetnas including Willow Creek and the
  Little Susitna will likely reach bankfull.

Hydrologic Concerns:

* Many lower locations along rivers such as gravel bars and other
  spots popular for camping and recreating may become inundated with
  water with rivers reaching bankfull conditions.

* Heavy rain may result in localized ponding in low-lying areas and
  locations with poor drainage.

Next Steps:

* Residents along area streams as well as river users and recreators
  should anticipate higher than normal water levels and are advised
  to monitor weather and river forecasts.

* Send weather or flooding reports to inws.ncep.noaa.gov/report/ or
  by calling 1-907-266-5127.

* Reports on river conditions may be sent to the river forecast
  center by calling 1-907-266-5160.
