GOES19 high‑energy (>2 MeV) electron flux has persisted at mainly High, with only a very brief drop out due to the CME impact on 25 Mar. This High flux is expected to persist for much of the period, only dropping out with any fast wind onset from CH34/+, most likely occurring on day 3-4 (28-29 Mar). 

The associated 24-hour electron fluence is expected to persisted at Active, with only a very slight decline likely continuing. This is supported by both MOSWOC REFM and 27-day recurrence. A more notable decline is then likely through day 4 (29 Mar) as a consequent of any flux drop out, however the timing and extent of this drop out remains low confidence.
