## extract

Hydrologic Outlook — Hatcher Pass; Western Susitna Valley; Southern Susitna Valley; Central Susitna Valley; Northern Susitna Valley
Severity: Unknown. Certainty: Possible.
ESFAFC

Locations:

* Yentna and Skwentna River basins
* Rivers, creeks, and streams with headwaters along the western
Talkeetna Mountains.

Timing:

* First Round - Late Monday Night through Wednesday Morning
* Second Round - Late Thursday Night through Saturday Evening

Rainfall:

* Widespread rainfall of 0.5 to 1.5 inches of rain is likely (70-80%)
across the Susitna Valley late Monday Night through Wednesday
morning. The highest amounts are very likely (80%-90%) to occur
from Petersville east to Talkeetna and along the Talkeetna
Mountains to Hatcher Pass.

* Additional widespread rainfall of 0.5 to 1.5 inches of rain is
likely (60-70%) across the Susitna Valley late Thursday Night
through Saturday evening. There is a low chance (20-30%) for
rainfall amounts higher than 1.5" across far northern and western
Susitna Valley.

* There is a chance (20-30%) of an additional 0.1 to 0.2 inches of
rain with any lingering scattered showers Wednesday afternoon and
evening.

Hydrologic Concerns:

* Expect sharp rises on many small streams and rivers, including the
Yentna at Lake Creek.

* 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.
