Flood Advisory issued June 20 at 5:33PM AKDT until June 22 at 10:00PM AKDT by NWS Anchorage AK

* WHAT…Flooding caused by snowmelt is expected.

* WHERE…the Yentna and Skwentna Rivers and other nearby
tributaries.

* WHEN…Until 1000 PM AKDT Sunday.

* IMPACTS…Minor flooding in low-lying and poor drainage areas.

* ADDITIONAL DETAILS…
– At 532 PM AKDT, Warm temperatures are resulting in rapid
snowmelt at higher elevations of the Western Alaska Range.
This is leading to higher water levels across much of the
Susitna Valley, especially along the Yentna and Skwentna
Rivers. This will lead to minor flooding in low lying areas
along these rivers this weekend. River levels will be highest
during the late afternoon and evening hours in response to
peak melting at the warmest time of day. Increasing cloud
cover this weekend through early next week, will lead to
gradual cooling of temperatures. Thus, snowmelt will lessen
by late Sunday and allow water levels to begin to fall.
