Winter Storm Watch
URGENT - WINTER WEATHER MESSAGE
National Weather Service Juneau AK
135 PM AKST Thu Dec 4 2025
...SNOW FOR THE NORTHERN PANHANDLE THIS WEEKEND...
.A pattern change will bring colder temperatures and strong
outflow winds extending southward starting Friday night. Forecast
confidence is increasing that this pattern change, in combination
with prolonged moisture, will produce accumulating heavy snow for
the highways and communities of the northern panhandle, including
the Klondike and Haines Highways, as well as the cities of Haines
and Skagway. Forecast confidence is not high enough for warning
level snowfall moving toward Juneau and the Icy Strait Corridor,
though the forecast continues to be monitored and updated through
the week. Cold temperatures are expected to continue to spread
southward into early next week, increasing potential for a long
duration snowfall event.

mph. Wind chills falling to as low as 35 below zero by Sunday
morning.
* WHERE...Thompson Pass.
* WHEN...From Friday morning through Sunday morning.
* IMPACTS...Visibilities reduced to one quarter mile or less due to
snow and blowing snow. Travel could be very difficult. Frostbite
may occur in as little as 10 minutes on exposed skin.
* ADDITIONAL DETAILS...An arctic airmass will drive colder air and
strong winds through Thompson Pass beginning Friday. The
combination of snow already on the ground, along with additional
snowfall expected and strong gap winds, will likely lead to snow
and blowing snow that may severely reduce visibility. Snow is
likely to taper off starting Sunday morning. However, gusty winds
will persist.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
A Winter Storm Watch for blizzard conditions means there is a
potential for falling and/or blowing snow with strong winds and
extremely poor visibilities. This can lead to whiteout conditions
and make travel very hazardous.

352 PM AKST Wed Dec 3 2025
..POTENTIAL REMAINS FOR SIGNIFICANT LONG DURATION SNOW EVENT LATE
THIS WEEKEND...
Multiple systems look to move through the region this coming
weekend. Temperatures and snow levels are expected to steadily
fall starting on Saturday through the weekend over the northern
panhandle.
Current forecast confidence is not high enough for warning level
snowfall moving toward the NE Gulf Coast and the Icy Strait
Corridor, including Juneau, Gustavus, Hoonah, and Yakutat. This is
primarily due to the timing challenge of when the transition from
rain to snow occurs and the amount of resulting accumulating
snowfall expected thereafter. However, forecast confidence remains
high on this staying a longer duration event through the weekend
once snowfall starts, with snow and colder temperatures continuing
to move southward across the panhandle into early next week.
Stay tuned to the forecast over the coming days as forecast
confidence improves on the extent and timing of this system.
