ESFAFC

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.
