...KUSKOKWIM RIVER BREAKUP FRONT LOCATION NEAR MOUTH OF JOHNSON
RIVER...

The River Watch team reports that the breakup front on the
Kuskokwim River is stalled at the mouth of the Johnson River, with
strong, intact ice extending downstream. Upstream ice is backing
up tightly to just below Napakiak, where water levels rose
Thursday afternoon, encroaching on low-lying roads and
structures. Minor flooding of these areas of Napakiak is likely.
Backwater from the ice jam is also elevating water levels upstream
to Bethel, reaching bankfull conditions and pushing water and ice
into Brown`s Slough. Above Bethel, ice runs thin out considerably
and the river now most likely ice free above Akiak.

NWS and the River Watch team will continue to reach out to local
community members for observations. To share any local
observations, please email anchorage.weather@noaa.gov.

Stay tuned for updates.
