Winter Weather Advisory

* 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.
