Weather alerts in Alaska

A strong storm system is expected to move into the northern half of the Alaska Panhandle and the northeast Gulf Coast tonight and continue through Tuesday. Beginning tonight for Haines, Skagway, and the two highways, periods of moderate to heavy rain will move over the area. Total rain accumulation are expected to be between 1.5-3.5 inches, with the heaviest rain late Tuesday morning into Tuesday afternoon. While substantial areal flooding is not expected at this time, isolated instances of minor ponding of water in low lying areas are possible. Furthermore, wet snow is possibly on the Klondike Highway near White Pass up to 3 inches through tonight, though warm surface temperatures may hinder these snow totals.

* 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.
