2 systems now and one more potentially in the Atlantic basin.
All Atlantic systems this year, though we are at I in the alphabet already, have been weak enough so far. Isaias a bit different, it exceeded the initial NHC speed predictions in very short order and even they are saying current wind speed estimate is probably conservative, but future forecast now seems downgraded a little again in the latest discussion (there were 80kt values previously)

Deep convection, with occasional overshooting cloud tops of -85C to
-90C just north of the center, has continued to develop during the
normal diurnal convective minimum period, which is quite impressive.
The most recent Air Force Reserve recon flight-level wind data,
along with ASCAT surface wind data, indicate that the inner-core and
outer wind field have both contracted in size. Furthermore, radar
data from the Bahamas and an 1810Z AMSR-2 microwave pass also
indicate that a small 10-nmi-wide mid-level eye is forming. The last
recon central pressure was 991 mb and the 700 mb height had
decreased by 30 meters since the earlier maximum height around
1230Z. These data indicate that Isaias is getting better organized.
The initial intensity remains 65 kt based on an earlier 700-mb
flight-level wind speed of 72 kt, which reduces to a 65-kt surface
wind speed using a 90-percent adjustment factor.
