In 1998 the first peak will be significant outburst from 1333 and 1366 trails (mostly from 133 trail). At 0 UT 17 November ZHR will rise to 200 meteors with brightness above average level. After that a very strong traditional maximum coinciding with maximum from 1965 trail will follow. At 14 UT 17 November activity will rise to 130-150 meteors on ZHR scale. Their brightness will be average or slightly below average. Finally, at 20 UT 18 November another small enhancement from 1333 trail is possible. Activity will rise to 30-40 meteors on ZHR scale, meteor brightness is average.

In 1999 a not very strong traditional maximum is expected, but it will sink in coming storm from 1899 trail (with addition from 1932 trail). At 2:42 UT 18 November 1899 trail will give a maximum of 2500 meteors on ZHR scale. Also, at 0:29 UT a submaximum from 1932 trail can appear. Meteor brightness during the storm will be a little below average. Another small outburst should happen at 18:59 UT 18 November. It will be connected with 1866 trail and ZHR will rise to about 50 meteors with brightness a little higher than average.

In 2000 several peaks are expected. The first will be background maximum of moderate intensity, but considering close comet 55P it can result in 40-45 meteors on ZHR scale. Then at 8:44 UT 17 November a maximum from 1932 trail will happen. Its intensity will be 250-300 meteors on ZHR scale, meteor brightness notably lower than average. The next outburst will be caused by 1733 trail. It will occur at 3:11 UT 18 November and activity will rise to 350 meteors on ZHR scale, brightness somewhat higher than average. Finally, at 7:20 UT 18 November a maximum from 1866 trail will take place. Its intensity will also be about 350 meteors on ZHR scale with brightness close to average level.
