Special Weather Statement issued September 12 at 11:26AM AKDT by NWS Juneau AK

Another front pushes into the panhandle early next week. Currently, there are two forecast solutions with one bringing the low pressure system closer to the panhandle allowing for more rain into the area, and the other keeps the low farther west. Although the first solution increases the chance for more rain, both forecast solutions bring rainfall totals to around 2 to 4 inches for many locations Monday through Wednesday, with locally higher amounts at the upper elevations. Freezing levels will still be high, around 6000 ft, allowing for extra melt near glacial systems. Due to heavy rainfall and elevated snow levels in combination with already saturated soils from previous rainfall, rises in area rivers and streams are expected. Stay tuned for updates on this next system through the weekend or visit weather.gov/juneau.

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.
