...HIT OR MISS SNOW SHOWERS CONTINUE INTO FRIDAY... .Snow showers from the Gulf of Alaska will continue through Friday morning at least. Additional snowfall accumulations of 3 to 7 inches are expected through Friday, with some locally higher amounts possible. A more organized area of showers is currently moving through the northern panhandle as of 3 pm Thursday, bringing heavier snow showers with visibilities down to less then a mile at times. However, accumulations will be limited during the daytime due to warmer temperatures as we are now into the latter half of March. In addition, snowfall accumulations will be widely variable across the area due to the hit or miss nature of the showers. Rates as high as 1 inch per hour and visibilities down to 1/2 mile or less will be possible within any heavier showers that repeatedly move over the same location. A relative lull in the heaviest bands of showers is likely for most areas later on Friday, but more snow will likely sweep into the panhandle for the weekend. * WHAT...Heavy snow. Additional snow accumulations of 4 to 7 inches. Visibilities reduced to 1/2 mile or less at times. * WHERE...Cape Fairweather to Lisianski Strait. * WHEN...Until 1 AM AKDT Friday. * IMPACTS...Travel will be difficult. * ADDITIONAL DETAILS...Heaviest snow showers are expected through Thursday night. Amounts could be highly variable.

If you must travel, keep an extra flashlight, food, and water with you in case of an emergency. People are urged to prepare their property before the onset of winter weather.

Additional snow accumulations of 3 to 5 inches. Visibilities reduced to 1 mile or less at times. * WHERE...Portions of Southeast Alaska. * WHEN...Until 4 AM AKDT Friday. * IMPACTS...Travel could be difficult. The hazardous conditions could impact the morning or evening commute. * ADDITIONAL DETAILS...Heaviest snow showers are expected during the day Thursday with the frequency gradually diminishing into Friday. Snow amounts could be highly variable with the higher amounts near the outer coast and near higher terrain. Skagway, the Klondike highway, and Sitka will see gusty winds to 40 mph Thursday evening with possible blowing snow on the Klondike highway.

...SNOW SHOWERS ON FRIDAY REPLACED BY ADVANCING SYSTEM SATURDAY... .Confidence is increasing on seeing a more significant round of snow this weekend as cold temperatures aloft remain in place and another round of moisture move in. There remains some uncertainty for snow accumulations at the surface as we are starting to see warmer day time temperatures into the mid to high 30s to around 40 due to increasing daylight and sun angle, however, temperatures aloft are still very favorable for accumulating snow amounts. If the heavier precipitation rates are significant enough to overcome the warmer surface temperatures, snow accumulations will be greater. But if the temperatures are able to overcome the precipitation rates, snowfall will be limited as it melts by the time it reaches the surface. This will need to be monitored for any changes in potential snow accumulation. The orientation of the low and where the showers move into the panhandle will also impact the snow amounts, with how northward and inland the heavier moisture will push and how organized the bands of snow are expected to be when moving through this weekend. * WHAT...Heavy snow possible. Total snow accumulations of 4 to 9 inches possible. Winds could gust as high as 40 mph. * WHERE...Skagway, Haines, Admiralty Island and Petersburg. * WHEN...From late tonight through Saturday evening. * IMPACTS...Travel could be very difficult and is discouraged. * ADDITIONAL DETAILS...During the daytime hours Friday, 1 to 4 new inches of snow are possible as snow showers continue to cycle through before a stronger system with additional snow accumulations arrives beginning late Friday night. Snow totals will be variable, as daytime heating may limit snowfall accumulation during daytime hours.

Monitor the latest forecasts for updates on this situation.
