* WHAT…Heavy snow and blowing snow expected. Total snow
accumulations of 8 to 20 inches, lowest amounts at sea level.
Northerly wind gusts as high as 50 to 65 mph. Visibility reduced
to one-half mile or less at times.
* WHERE…Eastern Aleutians.
* WHEN…From 4 AM Tuesday to 1 AM AKDT Thursday.
* IMPACTS…Travel could be very difficult. Areas of blowing snow
could significantly reduce visibility. Strong winds could result
in significant drifting of snow.
* ADDITIONAL DETAILS…Snow starting Tuesday morning picks up in
intensity throughout the day along with the gusty northerly winds.
The worst conditions look to be between Tuesday evening through
Wednesday evening before snow rates decrease. However, gusty
northerly winds, snow showers, and poor visibility could linger
into Thursday morning. Unalaska will likely see the worst
conditions and most snow accumulation with this storm. Akutan will
also see some snow, but warmer air looks to change precipitation
over to rain/snow mix potentially Tuesday afternoon and evening.
Nikolski will be cold enough for all snow but looks to be a little
too far west of the best moisture axis which will be over Unalaska.
