## extract

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

Locations:

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

Timing:

* Now through Wednesday (tomorrow) afternoon. Heaviest rainfall
expected from now through about midnight tonight.

Rainfall:

* The heaviest rain is ongoing. However, an estimated 1.5 to 2 inches
of rain have fallen along the Alaska Range and Talkeetna Mountains
so far today, with about 0.5 to 1 inches in Susitna Valley.
* Additional rainfall amounts of about 0.5 to 1.5 inches are forecast
from now through tomorrow afternoon.
* These rainfall totals likely won't be high enough for widespread
flooding, but smaller tributaries draining the Talkeetnas including
Willow Creek and the Little Susitna may 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.
