As Cyc stated, El Nino generally equals less hurricane activity, while La Nina usually causes increased hurricane activity. An El Nino will help increase wind shear (a big no-no for hurricane formation) over the tropical Atlantic, as well as supress the ITCZ (area of convection close to equator). A La Nina does the exact opposite; less shear and a more active ITCZ. Conversely, El Nino will increase the amount of high-latitude subtropical development, which is a big reason why we saw a lot of that occur last year. We typically see most of the activity occur in the low latitudes during a La Nina.
This year, we're in for neither of the two...or La Nina. So it's logical to thus expect more hurricane activity, especially in the low latitudes, this season. BUT, there are so many other factors that can, and have, canceled out ENSO. If all the other factors are inhibiting, 2003 could still be rather dull, even with a La Nina.
