The high energy electron flux (greater than 2MeV)  is expected to start the period at Normal Background to Moderate levels, with a probable decreasing trend in activity. The corresponding 24-hour electron fluence is also likely to show a declining response.

The Met Office REF Model output continues to give a clear signal for a decline in activity over the next couple of days and this signal is accepted as it appears to offer sound guidance. The 27-day recurrence data indicates a slow decline until later on Day 1 (5 June) when levels then became mostly stable with no particular trend in evidence.
