El Nino impacts the storms in numbers but not the intensity of the storms that do form, is that correct?

Both, actually.  El Niņo makes conditions unfavorable for tropical development in the Atlantic, hence the lower numbers of storms, and those same unfavorable conditions also make it harder for storms that do develop to strengthen as fully as they might otherwise have been able to do.  There are exceptions, of course, but, in general, El Niņo results in fewer and overall weaker storms in the Atlantic.

Unless the El Nino is weak. There was actually a weak El Nino in 2004-2005, and we saw what kind of hurricane season 2004 was. Hurricane Andrew also came at the tail end of an El Nino, but that didn't stop it from rapidly intensifying and devastating south Florida 23 years ago, 5 days to the day. We'll have to wait and see what impact this El Nino might have on Danny.
