…ACCUMULATING SNOW FOR PARTS OF SOUTHEAST ALASKA…
.Moisture rich onshore flow aloft will be lifted by the Coastal
Mountains, resulting in another round of accumulating snowfall
for Yakutat. Greatest snow rates will be associated with a warm
push aloft. As air warms aloft, expect snow characteristic to
become increasingly wet and dense before fully transitioning to
rain in the afternoon.
A second system will arrive Tuesday and sweep northward through
Wednesday. As the system moves into the Haines area, colder
temperatures will result in accumulating snow, with the greatest
snowfall accumulations expected for the Haines Highway. Snowfall
diminishes Wednesday afternoon as temperatures warm.
* WHAT…Heavy snow possible. Total snow accumulations of 3 to 7
inches possible.
* WHERE…Haines Borough, especially along the Haines Highway
and Klukwan.
* WHEN…From late Tuesday night through Wednesday afternoon.
* IMPACTS…Travel could be very difficult.
* ADDITIONAL DETAILS…Snowfall rates will be greatest late
Tuesday night into early Wednesday morning. Rain will begin
mixing in by Wednesday afternoon as warmer air starts to move
north.
