Additional Comments

The solar wind speed is slightly elevated relative to background levels. We anticipate a gradual return to background levels throughout the first and second forecast periods.
The arrival of a high-speed stream (HSS) from a recurrent trans-equatorial coronal hole is expected late in the third forecast period.
A large number of CMEs were observed lifting off the Sun over the weekend; however, we have not identified any Earth-directed component of concern thus far.
