Active to minor storm (G1) conditions are expected throughout the day with a chance for a major geomagnetic storm level (G2). CME effects are expected to wane by the end of the day, replaced by the arrival of a positive polarity CH/HSS on August 29. Unsettled to active conditions are expected on August 29.
