...SNOW AND FREEZING RAIN CONTINUE FOR THE NORTHERN PANHANDLE INTO MONDAY... .Snowfall and periods of freezing rain continue for much of the northern half of the panhandle from Juneau and Icy Strait corridor area northward. The rain snow line remains just south of the Icy Strait Corridor and Juneau. Snow totals have so far been around 15 to 40 inches across the northern panhandle. Some freezing rain has also been reported around Juneau, Gustavus and Yakutat. Through the day Monday, snowfall and freezing rain totals will diminish, but showers will continue to bring in additional periods of mixed precipitation, with heavier showers bringing more accumulating snow. Another surge of moisture may arrive Monday night, bringing more renewed snowfall rates with it. The rain/snow line wavers across the Icy Strait area through Tuesday. Please stay tuned to future updates on this impactful storm. * WHAT...Heavy mixed precipitation. Additional snow accumulations of 3 to 9 inches, with the higher totals out the road in Juneau, and ice accumulations of around one tenth of an inch. * WHERE...Glacier Bay and City and Borough of Juneau. * WHEN...Until 6 AM AKST Tuesday. * IMPACTS...Travel will be very difficult. The hazardous conditions could impact the morning or evening commute. * ADDITIONAL DETAILS...Additional accumulating snowfall totals will be highly variable. Expect less accumulating snow than in previous days across the area as precipitation becomes more convective in nature. The bulk of the additional snow accumulation will be where heavier showers move through, and out the road in Juneau. However, freezing rain will mix in at times on Monday throughout the area. Snowfall rates will pick up again late Monday night as a wave moves through, though this will be weaker than previous waves.

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. 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.
