NASA Captures Rare Arctic Storm Over Alaska, Revealing Unstable Atmospheric Conditions
NASA satellites captured striking images of a rare arctic storm over southern Alaska, marking the end of winter 2026 with colder-than-average temperatures and heavy snowfall. The atmospheric instability was highlighted by the formation of 'cloud streets' over the Gulf of Alaska, a phenomenon where cold, dry air flows over warmer waters, creating long, parallel bands of clouds. This setup was driven by a low-pressure system over the Gulf and high pressure across eastern Russia and northern Alaska, pushing frigid Arctic air southeastward. The storm system, identified as a polar low, reached tropical storm-force winds, generating snow and thunderstorms near its center. The event is part of a broader pattern of persistent cold and stormy weather in Alaska, with more unsettled conditions expected as an atmospheric river approaches.
