Special Weather Statement issued March 17 at 1:14PM AKDT by NWS Juneau AK

Effective: Tue March 17, 2026, 1:14 PM
Expires: Wed March 18, 2026, 12:00 PM

The low pressure system in the gulf will continue to push snow showers over SE AK through the week. With longer days, the southern panhandle is starting to see high temperatures increase into the high 30s to low 40s. Average snowfall accumulations should be around 1 to 3 inches per 24 hours, however due to the showery nature of the snow, accumulations will be highly variable with periods of melting in sunny breaks. Isolated areas and higher elevations could likely see higher snow amounts. The main impact from times of moderate snow will be lowered visibilities that could impact travel by air, land, and sea. Heaviest snow showers can quickly move over an area reducing visibilities to below one mile, with conditions quickly improving behind the shower.


Winter Weather Advisory issued March 17 at 3:56PM AKDT until March 18 at 10:00PM AKDT by NWS Juneau AK

Effective: Tue March 17, 2026, 3:56 PM
Expires: Wed March 18, 2026, 12:00 AM

...HIT OR MISS SNOW SHOWERS CONTINUE THROUGH THE WEEK... .The Winter Weather Advisories have been expanded in area and extended in time through Thursday morning as scattered to numerous bands snow showers are expected to continually push into the panhandle through the late week. Another organized band is likely to push through the area late Tuesday night through Wednesday morning. Snowfall accumulations of 6 to 10 inches are expected through Thursday, with some locally higher amounts possible. However, accumulations will be limited during the daytime due to warmer temperatures as we move into late March. In addition, snowfall accumulations will be widely variable across the advisory areas due to the hit or miss nature of the showers, however rates as high as 1 inch per hour will be possible within any heavier showers that repeatedly move over the same location. Advisories could be upgraded to short-fuse Winter Storm Warnings if heavier snow showers continue over the same area. * WHAT...Snow expected. Total snow accumulations of 2 to 4 inches. * WHERE...Prince of Wales Island. * WHEN...For the first Winter Weather Advisory, until 4 PM AKDT this afternoon. For the second Winter Weather Advisory, from 4 AM to 10 PM AKDT Wednesday. * IMPACTS...Travel could be very difficult. The hazardous conditions could impact the morning or evening commute. * ADDITIONAL DETAILS...Another heavier band of snow will move through late Tuesday night into Wednesday. Due to the showery nature of the snow, accumulations will be highly variable with periods of melting in sunny breaks. Highest accumulations expected at elevation and along interior roadways. Snow showers are expected to then continue through at least Thursday morning.

Slow down and use caution while traveling. People are urged to prepare their property before the onset of winter weather. For the latest road conditions, where available, call 5 1 1 or visit 511.alaska.gov.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
