152 PM AKDT Mon Jun 22 2026

...HEAVY RAIN POSSIBLE FOR THE ALASKA RANGE ON TUESDAY...

...Locations Impacted...
Eastern Alaska Range South of Trims Camp-Northern Denali
Borough-Southern Denali Borough-Eastern Alaska Range North of Trims
Camp

A front is expected to move westward over the state throughout the
beginning of this week. As this front progresses, we are expecting
widespread rain showers and thunderstorms to begin Tuesday morning
for the eastern Alaska Range and spread west by Tuesday afternoon
during the time of heaviest rainfall with totals as high as 1" or
more in some locations. Heavy rain may result in rapid rising waters
along rivers/streams coming out of the Alaska Range over the Tanana
Valley. However, flooding is not expected due to the dry antecedent
conditions. If you are partaking in any recreational activities,
please remain weather aware. We will continue to keep you updated if
more information becomes available.

103 PM AKDT Mon Jun 22 2026

...SIGNIFICANT RAINFALL TUESDAY INTO EARLY WEDNESDAY WILL BRING
RIVER RISES AND LOCALIZED FLOOD POTENTIAL TO THE SUSITNA VALLEY...

Rainfall

* Susitna Valley: Widespread rainfall totaling 1 to 2 inches with
  the highest totals likely across the northern and western portions
  of the valley.

Hydrologic Concerns

* Expect sharp rises on many small streams and rivers. Many smaller
  streams will crest Tuesday night into Wednesday with larger rivers
  cresting Wednesday into Thursday such as the Skwentna and Yentna
  rivers.

* 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 bankful conditions.

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

Confidence and Next Steps

* Confidence is moderate to high that heavy rainfall will occur
  across portions of Southcentral Alaska, with the northern/western
  Susitna Valley receiving the heaviest rainfall. Confidence is also
  moderate regarding rainfall totals and placement of heaviest
  rainfall. If forecast rainfall totals increase, flood watches or
  warning may be needed.

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

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