Geomagnetic Storm Category G2 Predicted
August 26, 2026 4:36 PM UTC
Space Weather Message Code: WATA30 Serial Number: 280 Issue Time: 2026 Aug 26 1636 UTC WATCH: Geomagnetic Storm Category G2 Predicted Highest Storm Level Predicted by Day: Aug 27: G1 (Minor) Aug 28: G2 (Moderate) Aug 29: G2 (Moderate) THIS SUPERSEDES ANY/ALL PRIOR WATCHES IN EFFECT Comment: HSS on 27 + CMEs on 28-29. CORRECTED NOAA Space Weather Scale descriptions can be found at www.swpc.noaa.gov/noaa-scales-explanation Potential 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.
