...WINTER STORM WATCH IN EFFECT FROM LATE SATURDAY NIGHT THROUGH SUNDAY AFTERNOON... * WHAT...Heavy snow possible. Total snow accumulations of 6 to 8 inches possible passed mile marker 20. For Haines, amounts up to 2 to 4 inches. * WHERE...Haines Highway and Klukwan. * WHEN...From late Saturday night through Sunday afternoon. * IMPACTS...Travel could be very difficult. * ADDITIONAL DETAILS...Ahead of this low, northerly flow would pull cooler air into the area, which would support snow. And as the low tracks into Canada, we would expect winds to stay out of the west, allowing for cooler air to continue to get pulled in and keep the chances for snow in the forecast. But the southerly push of wind could usher in warmer air that would switch the snow to rain. So low confidence on the precip type forecast for now. But if the temperature profile can stay cold enough to support snow, heavy snow would be likely late Saturday night into Sunday morning. PRECAUTIONARY/PREPAREDNESS ACTIONS... Monitor the latest forecasts for updates on this situation. &&
