Additional Comments

There remains a slight chance of ACTIVE periods early the first forecast interval due to a weak enhancement from a coronal hole high speed stream. There is also a chance for a glancing blow from weak a coronal mass ejection (CME) that left the Sun on 30 JUL. Should this CME arrive there may be a chance for some STORM G1 periods late in the first forecast interval. Solar wind parameters are then expected to return to ambient conditions through the second forecast interval.
