GOES19 >2 MeV electron flux will probably now remain at Moderate to High levels throughout much of this guidance period, as the high speed stream of CH98/+ gradually begins to wane. 

The associated 24 hour fluence will most probably remain above the Active (1e8 integrated pfu) threshold for much of the period, with a Slight Chance of becoming Very High (>1e9 integrated PFU). The reduction in confidence indicated in the probabilities is due to the uncertainty in the longevity of this event. This is supported by the REFM forecast.
