The high energy electron flux remains at largely high levels following CH17 high speed stream. Now that solar winds have returned to background levels, it is likely the electron flux will slowly decrease through the period, although may still peak at high levels throughout. There is a chance that a CME from August 20 may yet arrive on day 1 (although some signals suggest this may have already happened with little impact). As such, electron flux levels may decrease for time, then rebound to similar levels. 

The electron fluence remains above the active threshold, and is expected to remain above on day 1. The fluence is likely to gradually decrease through the period, although it remains likely that it will remain above the Active threshold into day 2 (with a slightly reduced probability due to possible CME effects). There is continued, although reduced chance of breaching the Active threshold on days 3 and 4.
