A fleet of Saildrone uncrewed surface vehicles is being deployed on a five-year mission to circumnavigate Antarctica, collecting continuous ocean and climate data in waters too remote and harsh for conventional research vessels. NOAA is involved in the effort, which aims to improve monitoring of the Southern Ocean's role in carbon uptake, heat storage and polar climate systems.

Forecasters at the National Oceanic and Atmospheric Administration are monitoring a winter storm expected to drop up to two feet of snow across three U.S. states by Monday. The system has prompted warnings as high pressure keeps skies clear in surrounding regions, and residents in affected areas are being urged to prepare for significant accumulation and travel disruption.

Forecasters at NOAA say multiple solar eruptions could trigger geomagnetic activity, pushing the northern lights as far south as the northern United States starting tonight. Skywatchers across northern states are being told to watch for auroras after dark. The alert has drawn wide attention as people check space weather forecasts for viewing chances.
