Event: Winter Weather Advisory
Area: Anchorage; Lower Matanuska Valley; Sutton / Upper Matanuska Valley
Severity: Moderate
Urgency: Expected
Certainty: Likely
Effective: 2026-10-20T04:52:00.000Z

* WHAT...Snow expected. Total snow accumulations between 2 and 6
inches, highest amounts near the mountains.

* WHERE...Lower elevations of Anchorage and the Matanuska Valley.

* WHEN...From 4 AM to 1 PM AKDT Tuesday.

* IMPACTS...Travel could be difficult. Be prepared for slippery
roads. Visibilities as low as one half mile possible, including
during the morning commute.

* ADDITIONAL DETAILS...Rain will intensify during the overnight hours
and change to  snow late tonight through early Tuesday morning,
with temperatures falling to near freezing. The heaviest snow and
highest accumulation will be near the mountains, from the lower
Anchorage Hillside to East Anchorage and up the Glenn Highway
corridor to Palmer and Sutton. Roads will start out wet and road
surface temperatures are still warm (in the upper 30s), but steady
moderate snow should be enough to lead to slushy accumulation,
especially along neighborhood roads. Snow will change back to rain
by late morning in south to west Anchorage, continue northward to
the Matanuska Valley in the afternoon. The exact timing of
changeover back to rain will greatly impact total snow amounts.
