A frontal boundary pushing into the western Bering and a second low east of the Kuril Islands and south of Attu affected the Kuskokwim Delta Coast, Nunuvak Island, Western Capes and Shemya April 2-3, 2024. The first low brought gusty winds, snow and low visibilities, along with cold air for this time of year, to the western and central Bering. A second low bombed out (with the surface low pressure decreasing more than 24 mb in 24 hours) as the low moved towards Attu and Shemya. By Tuesday afternoon, April 2 the pressure gradient force field spanned from St Matthew Island and Nunivak to Attu. This led to a small corridor of sustained hurricane force winds for the for the western Aleutian Islands, including Shemya.
