A Winter Storm Warning for snow means severe winter weather conditions will make travel very hazardous. If you must travel, keep an extra flashlight, food and water in your vehicle in case of an emergency.

* 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...Until 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 continues this morning and picks up in intensity throughout the day along with the gusty northerly winds. The worst conditions look to be between early this evening through Wednesday afternoon 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. With the storm tracking a little bit farther to the east, Akutan will see a longer period of snow before warmer air potentially works in to change precipitation over to rain/snow mix this evening into tonight. Nikolski will be cold enough for all snow but looks to be a little too far west of the moisture axis which will be over Unalaska.
