Special Weather Statement issued March 16 at 6:40AM AKDT by NWS Anchorage AK

Effective: Sun March 16, 2025, 6:40 AM
Expires: Sun March 16, 2025, 2:00 PM

Strong northwesterly winds up to 40 mph have developed across Shelikof Strait. These winds are resuspending ash from the 1912 Katmai-Novarupta eruption, potentially causing haze and trace amounts of ash accumulation. The villages of Karluk and Larsen Bay are most likely to be impacted. Those in sensitive groups or with respiratory ailments are encouraged to avoid or reduce outdoor activity to avoid inhaling the ash. The winds will weaken and shift to the west later this afternoon, which should end ash resuspension.

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.
