Forecaster summary - Issued 2018-11-30T00:04:15

The high energy electron flux (greater than 2 Mev) will start at background levels, but will increase during day 3 (3rd Dec) in response to the arrival of the HSS from CH53, reaching High flux levels (greater than 1000 pfu) during the diurnal peaks thereafter. The corresponding 24-hour fluence will start well below the High threshold, but is likely to show a rising trend during day 3 in response to the increasing flux levels, with the High fluence threshold (1e8 integrated pfu) likely to be breached during day 4 (3rd Dec).
