Winter Storm Watch

* WHAT...Moderate to heavy snowfall possible.

* WHERE...Anchorage and Eagle River (all elevations), East Turnagain Arm, Western Kenai Peninsula, Southern Kenai Mtns, Interior Kenai Peninsula, and Turnagain Pass.

* WHEN...From Saturday afternoon through late Sunday night.

* IMPACTS...Travel could be very difficult.

* ADDITIONAL DETAILS...Longwave troughing in the Bering Sea hedges east as inverted troughing in the Gulf of Alaska tracks west. A snow band will set up and stall over Anchorage/Kenai Peninsula tomorrow afternoon through Sunday bringing rounds of moderate to heavy snowfall. There is moderate uncertainty as to where the snow band will ultimately end up, resulting in lower confidence for snowfall amounts. Warmer temperatures filters in Sunday afternoon from east to west, transitioning snow to rain.

*Low/High end values are as follows:

- Anchorage/Eagle River & western Kenai Peninsula: 2-4" (Low end)/6-10" (High end). Higher elevations: up to a foot possible.

- Seward: 1-3" (Low end)/3-6" (High end).

- Turnagain Pass to Moose Pass: 7 to 11" possible.

- Portage: 9-11" with snowfall rates of up to 1" an hour.
