Hydrologic Outlook
National Weather Service Anchorage AK
326 PM AKDT Thu Aug 27 2026

...ANOTHER ROUND OF SIGNIFICANT RAINFALL THROUGH SATURDAY WILL BRING
RIVER RISES AND LOCALIZED FLOOD POTENTIAL TO SUSITNA VALLEY...

Locations:

* Yentna and Skwentna River basins
* Rivers, creeks, and streams with headwaters along the western
  Talkeetna Mountains, including Moose Creek near Oilwell Road

Timing:

* Tonight through Saturday Evening. Heaviest rain tonight through
  Friday morning.

Rainfall:

* Widespread rainfall of 0.5 to 1.5 inches of rain is likely (60-70%)
  across the Susitna Valley late tonight through Saturday evening.
  Highest rain amounts will likely be in Susitna Valley north of
  Talkeetna (including Petersville), and in Hatcher Pass.

Hydrologic Concerns:

* Expect sharp rises on many small streams and rivers, including the
  Yentna at Lake Creek. River rises from this storm will likely be
  less than was observed following the Tuesday storm.

* 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.
