Space Weather Message Code: WATA30Serial Number: 273Issue Time: 2026 May 13 0907 UTCWATCH: Geomagnetic Storm Category G2 Predicted Highest Storm Level Predicted by Day: May 14: None (Below G1) May 15: G2 (Moderate) May 16: G1 (Minor) THIS SUPERSEDES ANY/ALL PRIOR WATCHES IN EFFECT Comment:NOAA Space Weather Scale descriptions can be found atwww.swpc.noaa.gov/noaa-scales-explanationPotential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude.Induced Currents - Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms.Spacecraft - Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible.Radio - HF (high frequency) radio propagation can fade at higher latitudes.Aurora - Aurora may be seen as low as New York to Wisconsin to Washington state.
